8716318057 85xx: Reworked initial processor init
Reworked the initial processor initialzation sequence:
* introduced cpu_early_init_f that is run in address space 1 (AS=1)
* Moved TLB/LAW and CCSR init into cpu_early_init_f()
* Reworked initial asm code to do most of the core init before TLBs

The main reasons for these changes are to allow handling of 36-bit phys
addresses in the future and some of the issues that will exist when we
do that.

There are a few caveats on what can be initialized via the LAW and TLB
static tables:
* TLB entry 14/15 can't be initialized via the TLB table
* any LAW that covers the implicit boot window (4G-8M to 4G) must map to
  the code that is currently executing.

 * set_tlb() - write a tlb entry
 * invalidate_tlb() - invalidate a tlb array
 * disable_tlb() - disable a variable size tlb entry
 * init_tlbs() - setup initial tlbs based on static table

We should be able to use the same code on 86xx as well.

b8ec238503 85xx: add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

2146cf5682 Reworked FSL Book-E TLB macros to be more readable
The old macros made it difficult to know what WIMGE and perm bits
were set for a TLB entry.  Actually use the bit masks for these items
since they are only a single bit.

Also moved the macros into mmu.h out of e500.h since they aren't specific
to e500.

d111d6382c Empirically set cpo and clk_adjust for mpc85xx DDR2 support
This patch is against u-boot-mpc85xx.git of www.denx.com

Setting cpo to 0x9 for frequencies higher than 333MHz is verified on
both MPC8548CDS board and MPC8568MDS board, especially for supporting
533MHz DDR2.

Setting clk_adjust to 0x6(3/4 late cycle) for MPC8568MDS board is for
DDR2 on all current board versions especially ver 1.92 or later to bring
up.

39980c610c MPC85xx BA bits not set for 3-bit bank address DIMM
The current implementation does not set the number of bank address bits
(BA) in the processor. The default assumes 2 logical bank bits. This
works fine for a DIMM that uses devices with 4 internal banks (SPD
byte17 = 0x4) but needs to be set appropriately for a DIMM that uses
devices with 8 internal banks (SPD byte17 = 0x8).

61a21e980a 85xx start.S cleanup and exception support
From: Ed Swarthout <Ed.Swarthout@freescale.com>

Support external interrupts from platform to eliminate system hangs.
Define CONFIG_INTERRUPTS board configure option to enable.
Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC.

Remove extra cpu initialization redundant with hardware initialization.
Whitespace cleanup.

Define and use _START_OFFSET consistent with other processors using
ppc_asm.tmpl

Move additional code from .text to boot page to make room for
exception vectors at start of image.

Handle Machine Check, External and Critical exceptions.

Fix e500 machine check error determination in traps.c

TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.
