2013-03-14libpayload: Generalize and redistribute timekeeping codeGabe Black
The timekeeping code in libpayload was dependent on rdtsc, and when it was split up by arch, that code was duplicated even though it was mostly the same. This change factors out actually reading the count from the timer and the speed of the timer and puts the definitions of ndelay, udelay, mdelay and delay into generic code. Then, in x86, the timer_hz and timer_get_raw_value functions which used to be in depthcharge were moved over to libpayload's arch/x86/timer.c. In ARM where there isn't a single, canonical timer, those functions are omitted with the intention that they'll be implemented by a specific timer driver chosen elsewhere.

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.

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.
