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.

d435793229 Handle Asynchronous DDR clock on 85xx
The MPC8572 introduces the concept of an asynchronous DDR clock with
regards to the platform clock.

Introduce get_ddr_freq() to report the DDR freq regardless of sync/async
mode.

04db400892 Stop using immap_t on 85xx
In the future the offsets to various blocks may not be in same location.
Move to using CFG_MPC85xx_*_ADDR as the base of the registers
instead of getting it via &immap.

f59b55a5b8 Stop using immap_t for guts offset on 85xx
In the future the offsets to various blocks may not be in same location.
Move to using CFG_MPC85xx_GUTS_ADDR as the base of the guts registers
instead of getting it via &immap->im_gur.

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).
