Julius Werner dbadb1dd63 libpayload: Reorder default memcpy, speed up memset and memcmp
The current default memcpy first copies single bytes to align the
amount, then copies the rest as full words. In practice, the start of a
buffer is much more likely to be word-aligned then the end, and aligned
word access are usually more efficient. This patch reorders those
accesses to first copy as many full words as possible and then finish
the rest with byte accesses to optimize this common case.

This fixes a data abort when using USB on ARM without CONFIG_GPL. Due to
some limitations of how DMA memory is set up in coreboot on ARM, it
currently does not support unaligned accesses. (This could be fixed with
a more complicated patch, but it's usually not an issue... unless, of
course, your memcpy happens to be braindead).

Also add word-aligned accesses to memset and memcmp while I'm at it, and
make memcmp's return value standard's compliant.

Ronald G. Minnich c1ee8641cb libpayload: make functions static that are unused outside memory.c
The default_ functions in memory.c are only used to initialize a weak
variable.  They should not be used outside memory.c. Make them
invisible.

Remove the declaration from libpayload.h. For real this time.

Gabe Black c324794cb0 libpayload: Make the symbols in memory.c weak so they can be overridden.
The implementations for various stdlib functions in libc/memory.c are very
generic and should work under just about any circumstances. They are
unfortunately also very slow. This change makes them weak symbols so that
faster versions can be defined on a per architecture basis which will
automatically take the place of the slow versions.

Stefan Reinauer 14e2277962 Since some people disapprove of white space cleanups mixed in regular commits
while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)

Jordan Crouse 96f57aee0a libpayload: Fix the memcpy functions
There was a bit of confusion in the memcpy functions - we could simplify
things slightly without having to revert to 8 bit copies on a 32 bit
system.
