This adds support for the Freescale COM Express P2020 board. This board is similar to the P1_P2_RDB, but has some extra (as well as missing) peripherals.

Unlike all other mpc85xx boards, it uses a watchdog timeout to reset. Using the HRESET_REQ register does not work.

This board has no NOR flash, and can only be booted via SD or SPI. This procedure is documented in Freescale Document Number AN3659 "Booting from On-Chip RAM (eSDHC or eSPI)." Some alternative documentation is provided in Freescale Document Number P2020RM "P2020 QorIQ Integrated Processor Reference Manual" (section 4.5).

The CCSR relocation issue is solved by Timur's 5 part patchset containing the patch "powerpc/85xx: resize the boot page TLB before relocating CCSR".

This patch is checkpatch clean using the checkpatch and configuration file provided in the patch from Joe Hershberger titled "tools: checkpatch.pl from Linux added to tools".

Changes v2 -> v3: - re-enable CCSR relocation

Changes v1 -> v2: - fix checkpatch warnings - remove all references to NAND - update to top of tree U-Boot - remove CCSR relocation (top of tree code doesn't work)
