2012-11-23libpayload: Fix memalign() for fragmented alignment regionsNico Huber
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.

2012-11-08Refactor the endianness conversion functions and header files.Gabe Black
The endianness of an architecture is now set up automatically using Kconfig and some common code. The available conversion functions were also expanded to go to or from a particular endianness. Those use the abbreviation le or be for little or big endian. Built for Stumpy and saw coreinfo cbfs support work which uses network byte order. Used the functions which convert to little endian to implement an AHCI driver. The source arch is also little endian, so they were effectively (and successfully) inert.

2012-11-07libpayload: Make the symbols in memory.c weak so they can be overridden.Gabe Black
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.

2012-03-21Fix libpayload alloc() size and gcc pointer optimization problems.Marc Jones
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.

Adding -Os to the CFLAGS gains us about 25% smaller code (give or take).

Oh, well - add a quick strcpy() function and we're good.
