Nico Huber 3665ace13d libpayload: Remove unused FLAG_USED from memory allocator
The FLAG_USED bit in the memory allocator's header type was never
read. This removes it to save one bit for the region size so we can
have heaps of up to 32MiB.

Nico Huber 7a32e88f12 libpayload: Fix memalign() for fragmented alignment regions
Found a bug in the memory allocator ;-)

If the total free space in an alignment region is large enough for an
allocation but fragmented, such that there is no contiguous, sufficient
large, free space in the region, memalign() was looking at the same
region again and again in an endless loop. The advancing to the next
region was just missing.

Marc Jones ccee6256b4 Fix libpayload alloc() size and gcc pointer optimization problems.
The previous commit was incomplete and missed setting the entire
alloc area.

There are also additional problems with gcc optimizations of the
pointer math. The "auto" casting by gcc wouldn't return warnings,
but it was causing the optimization to be incorrect. We are now
very explicit in the casting in the pointer math.

Marc Jones 987e883e6a Make libpayload alloc() memory pointers volatile
gcc4.6.2 was optimizing the libpayload alloc() function and failing to
reload a pointer after the memory had been manipulated by a pointer in
the inlined function setup(). Change the pointer type to volatile
and now pass it to the setup() function. Also clean up the
declaration so that it isn't cast a bunch times in the function.

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 :-)

Patrick Georgi d385ed29b9 This change adds PPC support to libpayload, and hooks it up in the build
process.
The PPC support is still stubbed, with commented out x86 code as guide
line for an implementor.

Jordan Crouse 24a0404759 libpayload: Fix malloc allocation
Apparently the previous version worked on luck.  Fix the allocation
and add parens to better guide the compiler.  Also, halt() if 
the heap is poisoned (like by an overrun).  Finally, fix calloc()
so that it actually works.
