b13120d23b Blackfin arch: fix bug - crashes in tcp_v4_send_reset
Michael says that some bugs are crashes in tcp_v4_send_reset.
There's a missing clobber of "CC" in our checksum assembly
statement; fixing this makes the generated code look much saner.

dd3dd384df Blackfin arch: rewrite dma_memcpy() and dma in/out functions
- unify all dma in/out functions (takes ~35 lines of code now)
- unify dma_memcpy with dma in/out functions (1 place that touches MDMA0
  registers)
- add support for 32bit transfers
- cleanup dma_memcpy code to be much more readable
- irqs are disabled only while programming MDMA registers rather than
  the entire transaction

6f985294f7 Blackfin arch: fix bugs in linker script when using upstream binutils
Fix a few problems I discovered when building a kernel with upstream CVS
binutils.

We have to add the NOTES macro to our linker script, since a kernel
built with --build-id is otherwise unable to boot.  Last time NOTES was
added, it broke things, but the definition of the macro has changed not
to rely on parts of the linker script that aren't present on Blackfin.

I also noticed that _l2_lma_start does not point into the kernel image,
but rather somewhere in L1/L2 space, which seems unintended.  Also, when
the L2 section was added to the linker script, the part following it which
computes then length of the init section was not updated.
