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.

2013-03-13libpayload: Make whether or not there's an IO address space configurableGabe Black
Default it to no to be consistent with the other architecture wide options (endianness), and turn it on explicitly for x86 and PowerPC.

2012-11-09libpayload: Add an option to skip console initialization on startup.Gabe Black
A payload may want to decide whether it uses certain input/output consoles, or that it wants support for outputing to a particular device but not to use that device as a console. This change adds a config option which skips the call to console_init in start_main.

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.
