d26cd57071 [POWERPC] New registration for common Xilinx Virtex ppc405 platform devices
Currently virtex support in mainline make use of the infrastructure in
arch/ppc/syslib/ppc_sys.c for registering common devices on virtex ppc405
platforms.  The ppc_sys.c code is not well suited to the dynamic nature of
FPGA designs and makes adding new board ports more complex.  This patch
adds a new listing of common devices which does not depend on the ppc_sys.c
infrastructure.

2b10caf380 [POWERPC] Rework Kconfig dependancies for Xilinx Virtex ppc405 platform
Reverse dependency order for Xilinx Virtex parts.  For these parts, It
makes more sense for boards/chips to specify which features they
provide instead of the features listing the parts they are implemented
in.  I think it also makes adding new board ports simpler.

70093cfde8 ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts
Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM.  As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.

This irritated or annoyed many users and distributors.  Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.

Therefore
  - remove the offending kernel config option
    IEEE1394_CONFIG_ROM_IP1394,
  - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
    loaded.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .

To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:

install ohci1394 /sbin/modprobe eth1394; \
                 /sbin/modprobe --ignore-install ohci1394

Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.

fd2f3bddae ieee1394: replace vmalloc by kmalloc in csr1212
The biggest chunk ever allocated by CSR1212_MALLOC is 1024 Bytes +
sizeof(struct csr1212_csr_rom_cache) big.  Most of the time much
smaller data structures are allocated.  Therefore vmalloc is a waste.

The one exception is csr1212_append_new_cache() which is called to
append a chunk of CSR1212_EXTENDED_ROM_SIZE + sizeof(struct
csr1212_csr_rom_cache) if the currently allocated ROM cache is too
small.  CSR1212_EXTENDED_ROM_SIZE is generously defined as 256 kBytes.
In SVN commit 1220, Steve Kinneberg lowered this to 2 kBytes in the
config_rom_2.4 branch.  This same commit also switched CSR1212_MALLOC
from kmalloc to vmalloc in the SVN trunk branch:

(It was actually 2 kB, not 8 kB.)
>   - Fix hpsb_allocate_and_register_addrspace() to not allocate space

>   - Fix problems in csr1212.c filling ConfigROM images when extend

I am now setting CSR1212_EXTENDED_ROM_SIZE to 2 kB minus the overhead of
struct csr1212_csr_rom_cache.  Note, this code path is not used by the
in-kernel drivers though.  raw1394 could trigger it, but the respective
libraw1394 functions don't exist yet.

Furthermore, userspace programs can replace the entire local ROM via
raw1394.  If kmalloc does not fulfill their needs --- well, tough luck.
I decree that nobody needs such huge extended ROMs.  (Extended ROMs are
defined by IEEE 1212 clause 7.7.18.  The spec does not impose
practically relevant restrictions on the size of extended ROM chunks.)

Another potentially demanding use of CSR1212_MALLOC is if external
FireWire devices come with Extended ROM entries.  If they are too big
for kmalloc (or have been too big for vmalloc) we just fail to read
their ROM.  This is quite unlikely though, to my knowledge.
