Blackfin: turn off caches when self initializing
When bootstrapping ourselves on the fly at runtime (via "go"), we need to
turn off the caches to avoid taking software exceptions. Since caches
need CPLBs and CPLBs need exception handlers, but we're about to rewrite
the code in memory where those exception handlers live, we need to turn
off caches first.
This new code also encourages a slight code optimization by storing the
MMR bases in dedicated registers so we don't have to fully load up the
pointer regs multiple times.

fsl_ddr: Don't use full 64-bit divides on 32-bit PowerPC
The current FreeScale MPC-8xxx DDR SPD interpreter is using full 64-bit
integer divide operations to convert between nanoseconds and DDR clock
cycles given arbitrary DDR clock frequencies.
Since all of the inputs to this are 32-bit (nanoseconds, clock cycles,
and DDR frequencies), we can easily restructure the computation to use
the "do_div()" function to perform 64-bit/32-bit divide operations.
On 64-bit this change is basically a no-op, because do_div is
implemented as a literal 64-bit divide operation and the instruction
scheduling works out almost the same.
On 32-bit PowerPC a fully accurate 64/64 divide (__udivdi3 in libgcc) is
over 1.1kB of code and thousands of heavily dependent cycles to compute,
all of which is linked from libgcc. Another 1.2kB of code comes in for
the function __umoddi3.
It should be noted that nothing else in U-Boot or the Linux kernel seems
to require a full 64-bit divide on my 32-bit PowerPC.

Rather than allow a board to choose which version to support, NXID v0 is
now considered deprecated. The EEPROM code is updated to support only
NXID v1, but it can still read EEPROMs formatted with v0. In these cases,
the EEPROM data is loaded and the CRC is verified, but the data is stored
into a v1 data structure. If the EEPROM data is written back, it is
written in v1 format. This allows existing v0-formatted EEPROMs to
continue providing MAC addresses, but any changes to the data will force

Fix build problems caused by "_end" -> "__bss_end__" rename
Commit 44c6e65 "rename _end to __bss_end__ broke building of a large
number of systems (at least all PowerPC?):
libstubs.o: In function `app_startup':
examples/standalone/stubs.c:197: undefined reference to `__bss_end__'
The rename should not be done for the files in the
examples/standalone/ directory, as these are not using the code from
start.S, but do their own BSS clearing, and either use their own
linker scripts or the ones provided by the compilers.

powerpc/85xx: Handle PCIe initialization requires for P1021 class SoCs
The P1011, P1012, P1015, P1016, P1020, P1021, P1024, & P1025 SoCs require
that we initialize the SERDES registers if the lanes are configured for
PCIe. Additionally these devices PCIe controller do not support ASPM
and we have to explicitly disable it.

cfi_flash: fix bug with flash banks with different sector numbers
The function find_sector() does not take into account if the flash bank
has changed since the last call. This could lead to illegal accesses inside
and beyond the flash_info_t info strcture. For example if the current
flash bank has less sectors than the last used flash bank.
This patch adds two cheks. One that insures, that the current sector does
not exceed the allowed maximum (which is always a good idea). And one that
checks if the current access is to the same flash bank as the last access.
If not, the search loop will start with sector 0.
