Add a new 'pci enum' command which re-enumerates the PCI buses.  This
command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful
in boards with FPGAs connected via PCI/PCIe, boards that support PCI
hot-plugging, or during PCI debug.

Also enable the 'pci enum' command for X-ES's Freescale-based boards.

If a NOR flash is write protected it can not be initialized/detected so
add the ability for boards to skip NOR initialization on bootup.  A
board can skip NOR initialization by implementing the
board_flash_wp_on() function.

Some OSes require that secondary cores not be initialized when they
are booted (eg VxWorks).  By default when U-Boot is compiled with the
CONFIG_MP option all secondary cores are brought out of reset and held
in spinloops.  Setting the "mp_holdoff" environment variable to 'yes'
or '1' will cause U-Boot to leave secondary cores in their default
state.

The memory test is performed after DDR initialization when U-boot stills runs
in flash and cache. On recent mpc85xx platforms, the total memory can be more
than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a
sliding TLB window. After the testing, DDR is remapped with up to 2GB memory
from the lowest address as normal.

If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for
further debugging.

The device tree (fdt) must always exist in within the bootmap (usually the
first 16MB of RAM).  If it doesn't, then boot_relocate_fdt() will allocate
an LMB region in the bootmap and copy the fdt into that region.  It will
also increase the size of the fdt.

If the fdt is already in the bootmap, then previously the memory was just
reserved.  There was no contingency if the reservation failed, however.

By always allocating an lmb region and copying/resizing the fdt into that
region, the code is simplified and the memory region is always allocated
properly.

Also change the types of some variables to avoid some typecasts.

Last commit 3831530da was intended
"explicitly specify FAT12/16 root directory parsing buffer size, instead
of relying on cluster size". Howver, the underlying function requires
the size of the buffer in blocks, not in bytes, and instead of passing
a double sector size a request for 1024 blocks is sent. This generates
a buffer overflow with overwriting of other structure (in the case seen,
USB structures were overwritten).
