85xx: Reworked initial processor init

2008-01-17T08:04:53+00:00

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.

85xx: Move LAW init code into C

2008-01-17T05:21:55+00:00

Move the initialization of the LAWs into C code and provide an API
to allow modification of LAWs after init.

Board code is responsible to provide a law_table and num_law_entries.

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

Stop using immap_t on 85xx

2007-12-12T04:34:20+00:00

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.

Stop using immap_t for cpm offset on 85xx

2007-12-12T04:34:19+00:00

In the future the offsets to various blocks may not be in same location.
Move to using CFG_MPC85xx_CPM_ADDR as the base of the CPM registers
instead of getting it via &immap->im_cpm.

Fix minor 85xx warnings

2007-08-14T06:39:14+00:00

Some patches had inserted warnings into the build:
* mpc8560ads declared data without using it
* cpu_init declared ecm and immap without using it in all CONFIGs
* MPC8548CDS.h had its default filenames changed so that they contained
  "\m" in the paths.  Made the defaults not Windows-specific (or
  anything-specific)
