The #define USPRG0 aliases SPRN_USPRG, but it should refer to
SPRN_USPRG0. There is no register SPRN_USPRG on PowerPC.

Import U-Boot start-up code from version git-9407c3fc to include the
latest CPUs errata and make future U-Boot code inclusion easier. The
code import is limited to the currently supported CPUs P2020/MPC8544.

TLB support for the 85xx CPUs has been upgraded to support the MMUv2
page size definitions. This has been imported from U-Boot version
git-9407c3fc. This allows for future CPUs to make use of the new MMU
support.

Also the definition of MAX_MEM_MAPPED has been changed to avoid type
casting with "min" macro.

Definitions are added to support the mpc8544 sOC.

The function returning the I2C bus frequency is updated
to take into account the mpc8544 specific clock ratio.
A mininal GPIO API is added to enable and set the GPIO
out pins.

For the MPC85xx family of SOCs Linux expects any boot firmware
information to be passed in the first 64MiB of memory. This adds support
to ensure that the device tree is relocated to a valid location if it is
outside that address range.

For the other SOC family currently present in the ppc architecture, the
default is not to relocate as at Linux startup the virtual address
equals the physical address.

This adds support for populating derived properties of the mpc85xx SOC
which are not typically included in the dtb directly.

This update is based on U-Boot code from common/fdt_support.c
and arch/powerpc/cpu/mpc85xx/fdt.c - version git-2b26201.
