Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards. This makes the code easier to read and more flexible.
Delete pixis.h, because none of the exported functions were actually being
used by any other file. Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.
Remove some unnecessary #includes.
Make 'pixis_base' into a macro, so that we don't need to define it in every
function.
Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.
Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.
Replace ulong/uint with their spelled-out equivalents. Remove unnecessary
typecasts, changing the types of some variables if necessary.
Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets. No current boards appears to need this feature.
Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD.
Apparently, "pixis_reset altbank" has never worked on this board.

After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly. This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.
On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way. If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation. The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).
Currently we are limited to power of two sized DDR since we only use a
single bat. If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.
