[PATCH V5 0/9] MPC85xx support

[Renaud Barbier]

This patchset splits the bigger patch [V4 2/4] to make it easier to read.

It includes the base MPC85xx infrastructure required for a minimal
boot target in 32 bit addressing mode using an e500v2 core.

Also support is added for a minimal Freescale P2020RDB platform with
driver support currently limited to NOR and serial port only.

Renaud Barbier (9):
  Initial Freescale 85xx Headers.
  Initial e500v2 start up code
  e500v2 traps and TLB support code
  85xx: LAW and LBC initialization
  85xx clocking support
  MPC85xx start-up support code
  Set _text_base to the firmware relocation address
  85xx core support build files
  Minimal P2020RDB platform support and configuration file
