MPC5200: workaround data corruption for unaligned local bus accesses

2010-06-23T00:09:20+00:00

The MPC5200 has a nasty problem that will cause silent data corruption
when performing unaligned 16 or 32 byte accesses when reading from the
local bus - typically this affects reading from flash. The problem can
be easily shown:

This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.

Tested on lite5200b and TQM5200S.

UBI: initialise update marker

The in kernel copy of a volume's update marker is not initialised from the
volume table. This means that volumes where an update was unfinnished will
not be treated as "forbidden to use". This is basically that the update
functionality was broken.

remove myself as a maintainer of several ARM boards

Since I haven't been actively maintaining these boards for a long while,
keeping myself as their maintainer makes no sense.

Makefile: always call date with LC_ALL=C set

2010-06-22T20:40:43+00:00

Ensure that date is called only with LC_ALL=C locale set to make dates
locale neutral thus preventing lurking of non-ASCII characters into
U-Boot binary.

ARM: Align stack to 8 bytes

2010-06-22T20:15:07+00:00

The ARM ABI requires that the stack be aligned to 8 bytes as it is noted
in Procedure Call Standard for the ARM Architecture:
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html

Unaligned SP also causes the problem with variable-length arrays
allocation when VLA address becomes less than stack pointer during
aligning of this address, so the next 'push' in the stack overwrites
first 4 bytes of VLA.
