Russell King	07a496de4c	ARM: omap2: remove unnecessary boot_lock ... The boot_lock is something that was required for ARM development platforms to ensure that the delay calibration worked properly. This is not necessary for modern platforms that have better bus bandwidth and do not need to calibrate the delay loop for secondary cores. Remove the boot_lock entirely.

Nishanth Menon	2f8b5b2183	ARM: DRA7/OMAP5: Enable ACTLR[0] (Enable invalidates of BTB) for secondary cores ... Call secure services to enable ACTLR[0] (Enable invalidates of BTB with ICIALLU) when branch hardening is enabled for kernel. On GP devices OMAP5/DRA7, there is no possibility to update secure side since "secure world" is ROM and there are no override mechanisms possible. On HS devices, appropriate PPA should do the workarounds as well.

Tony Lindgren	351b7c4907	ARM: omap2+: Revert omap-smp.c changes resetting CPU1 during boot ... Commit 3251885285 ("ARM: OMAP4+: Reset CPU1 properly for kexec") started unconditionally resetting CPU1 because of a kexec boot issue I was seeing earlier on omap4 when doing kexec boot between two different kernel versions. This caused issues on some systems. We should only reset CPU1 as a last resort option, and try to avoid it where possible. Doing an unconditional CPU1 reset causes issues for example when booting a bootloader configured secure OS running on CPU1 as reported by Andrew F. Davis <afd@ti.com>. We can't completely remove the reset of CPU1 as it would break kexec booting from older kernels. But we can limit the CPU1 reset to cases where CPU1 is wrongly parked within the memory area used by the booting kernel. Then later on we can add support for parking CPU1 for kexec out of the SDRAM back to bootrom. So let's first fix the regression reported by Andrew by making CPU1 reset conditional. To do this, we need to: 1. Save configured AUX_CORE_BOOT_1 for later 2. Modify AUX_CORE_BOOT_0 reading code to for HS SoCs to return the whole register instead of the CPU mask 3. Check if CPU1 is wrongly parked into the booting kernel by the previous kernel and reset if needed Fixes: 3251885285 ("ARM: OMAP4+: Reset CPU1 properly for kexec") Reported-by: Andrew F.

Nishanth Menon	c0053bd50a	ARM: OMAP5 / DRA7: Introduce workaround for 801819 ... Add workaround for Cortex-A15 ARM erratum 801819 which says in summary that "A livelock can occur in the L2 cache arbitration that might prevent a snoop from completing. Under certain conditions this can cause the system to deadlock. " Recommended workaround is as follows: Do both of the following: 1) Do not use the write-back no-allocate memory type. 2) Do not issue write-back cacheable stores at any time when the cache is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it is implementation defined whether cacheable stores update the cache when the cache is disabled it is not expected that any portable code will execute cacheable stores when the cache is disabled. For implementations of Cortex-A15 configured without the “L2 arbitration register slice” option (typically one or two core systems), you must also do the following: 3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111 So, we provide an option to disable write streaming on OMAP5 and DRA7. It is a rare condition to occur and may be enabled selectively based on platform acceptance of risk. Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3] is set to 0. Based on ARM errata Document revision 18.0 (22 Nov 2013) Note: the configuration for the workaround needs to be done with each CPU bringup, since CPU0 bringup is done by bootloader, it is recommended to have the workaround in the bootloader, kernel also does ensure that CPU0 has the workaround and makes the workaround active when CPU1 gets active. With CONFIG_SMP disabled, it is expected to be done by the bootloader. This does show significant degradation in synthetic tests such as mbw (https://packages.qa.debian.org/m/mbw.html) mbw -n 100 100|grep AVG (on a test platform) Without enabling the erratum: AVG Method: MEMCPY Elapsed: 0.13406 MiB: 100.00000 Copy: 745.913 MiB/s AVG Method: DUMB Elapsed: 0.06746 MiB: 100.00000 Copy: 1482.357 MiB/s AVG Method: MCBLOCK Elapsed: 0.03058 MiB: 100.00000 Copy: 3270.569 MiB/s After enabling the erratum: AVG Method: MEMCPY Elapsed: 0.13757 MiB: 100.00000 Copy: 726.913 MiB/s AVG Method: DUMB Elapsed: 0.12024 MiB: 100.00000 Copy: 831.668 MiB/s AVG Method: MCBLOCK Elapsed: 0.09243 MiB: 100.00000 Copy: 1081.942 MiB/s Most benchmarks are designed for specific performance analysis, so overall usecase must be considered before making a decision to enable/disable the erratum workaround.

Lennart Sorensen	999f934de1	ARM: omap5/dra7xx: Enable booting secondary CPU in HYP mode ... If the boot loader enables HYP mode on the boot CPU, the secondary CPU also needs to call into the ROM to switch to HYP mode before booting. The firmwares on the omap5 and dra7xx unfortunately do not take care of this, so it has to be handled by the kernel. This patch is based on "[PATCH 2/2] ARM: OMAP5: Add HYP mode entry support for secondary CPUs" by Santosh Shilimkar <santosh.shilimkar@ti.com>, except this version does not require a compile time CONFIG to control if it should enable HYP mode or not, it simply does it based on the mode of the boot CPU, so it works whether the CPU boots in SVC or HYP mode, and should even work as a guest kernel inside kvm if qemu decides to support emulating the omap5 or dra7xx.

Paul Gortmaker	8bd26e3a7e	arm: delete __cpuinit/__CPUINIT usage from all ARM users ... The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

While waking up CPU from off state using clock domain force wakeup, restore the CPU power state to ON state before putting CPU clock domain under hardware control. Otherwise CPU wakeup might fail. The change is recommended for all OMAP4+ devices though the PRCM weakness was observed on OMAP5 devices first. As a result of weakness, lock-up is observed inside the hardware state machine of local CPU PRCM and results are UN-predictable as per designers. In software testing, we have seen hard-locks most of the time where system gets frozen. With power domain state restored, system behaves correctly. So update the code accordingly.

'Workaround for ROM bug because of CA9 r2pX gic control' register change disables the gic distributor while the secondary cpu is being booted. If a localtimer interrupt on the primary cpu occurs when the distributor is turned off, the interrupt is lost, and the localtimer never fires again. Make the primary cpu wait for the secondary cpu to reenable the gic distributor (with interrupts off for safety), and then check if the pending bit is set in the localtimer but not the gic. If so, ack it in the localtimer, and reset the timer with the minimum timeout to trigger a new timer interrupt.

Santosh Shilimkar	ff999b8a09	ARM: OMAP4460: Workaround for ROM bug because of CA9 r2pX GIC control register change. ... On OMAP4+ devices, GIC register context is lost when MPUSS hits the OSWR(Open Switch Retention). On the CPU wakeup path, ROM code gets executed and one of the steps in it is to restore the saved context of the GIC. The ROM Code GIC distributor restoration is split in two parts: CPU specific register done by each CPU and common register done by only one CPU. Below is the abstract flow. ............................................................... - MPUSS in OSWR state. - CPU0 wakes up on the event(interrupt) and start executing ROM code. [..] - CPU0 executes "GIC Restoration:" [...] - CPU0 swicthes to non-secure mode and jumps to OS resume code. [...] - CPU0 is online in OS - CPU0 enables the GIC distributor. GICD.Enable Non-secure = 1 - CPU0 wakes up CPU1 with clock-domain force wakeup method. - CPU0 continues it's execution. [..] - CPU1 wakes up and start executing ROM code. [..] - CPU1 executes "GIC Restoration:" [..] - CPU1 swicthes to non-secure mode and jumps to OS resume code. [...] - CPU1 is online in OS and start executing. [...] - GIC Restoration: /* Common routine for HS and GP devices */ { if (GICD != 1) { /* This will be true in OSWR state */ if (GIC_SAR_BACKUP_STATE == SAVED) - CPU restores GIC distributor else - reconfigure GIC distributor to boot values. GICD.Enable secure = 1 } if (GIC_SAR_BACKUP_STATE == SAVED) - CPU restore its GIC CPU interface registers if saved. else - reconfigure its GIC CPU interface registers to boot values. } ............................................................... So as mentioned in the flow, GICD != 1 condition decides how the GIC registers are handled in ROM code wakeup path from OSWR. As evident from the flow, ROM code relies on the entire GICD register value and not specific register bits. The assumption was valid till CortexA9 r1pX version since there was only one banked bit to control secure and non-secure GICD. Secure view which ROM code sees: bit 0 == Enable Non-secure Non-secure view which HLOS sees: bit 0 == Enable secure But GICD register has changed between CortexA9 r1pX and r2pX. On r2pX GICD register is composed of 2 bits. Secure view which ROM code sees: bit 1 == Enable Non-secure bit 0 == Enable secure Non-secure view which HLOS sees: bit 0 == Enable Non-secure Hence on OMAP4460(r2pX) devices, if you go through the above flow again during CPU1 wakeup, GICD == 3 and hence ROM code fails to understand the real wakeup power state and reconfigures GIC distributor to boot values. This is nasty since you loose the entire interrupt controller context in a live system. The ROM code fix done on next OMAP4 device (OMAP4470 - r2px) is to check "GICD.Enable secure != 1" for GIC restoration in OSWR wakeup path. Since ROM code can't be fixed on OMAP4460 devices, a work around needs to be implemented. As evident from the flow, as long as CPU1 sees GICD == 1 in it's wakeup path from OSWR, the issue won't happen. Below is the flow with the work-around. ............................................................... - MPUSS in OSWR state. - CPU0 wakes up on the event(interrupt) and start executing ROM code. [..] - CPU0 executes "GIC Restoration:" [..] - CPU0 swicthes to non-secure mode and jumps to OS resume code. [..] - CPU0 is online in OS. - CPU0 does GICD.Enable Non-secure = 0 - CPU0 wakes up CPU1 with clock domain force wakeup method. - CPU0 waits for GICD.Enable Non-secure = 1 - CPU0 coninues it's execution. [..] - CPU1 wakes up and start executing ROM code. [..] - CPU1 executes "GIC Restoration:" [..] - CPU1 swicthes to non-secure mode and jumps to OS resume code. [..] - CPU1 is online in OS - CPU1 does GICD.Enable Non-secure = 1 - CPU1 start executing [...] ............................................................... With this procedure, the GIC configuration done between the CPU0 wakeup and CPU1 wakeup will not be lost but during this short windows, the CPU0 will not receive interrupts. The BUG is applicable to only OMAP4460(r2pX) devices. OMAP4470 (also r2pX) is not affected by this bug because ROM code has been fixed.

Tony Lindgren	dbc0416104	ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+ ... As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.
