ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1

2008-06-03T18:21:53+00:00

This patch removes all SDRAM related defines from the PPC4xx headers
ppc405.h and ppc440.h. This is needed since now some 405 PPC's use
the same SDRAM controller as 440 systems do (like 405EX and 440SP).

It also introduces new defines for the equipped SDRAM controller based on
which PPC variant is used. There new defines are:

used on 405GR/CR/EP and some Xilinx Virtex boards.

used on 440GP/GX/EP/GR.

used on 440EPx/GRx.

used on 405EX/r/440SP/SPe/460EX/GT.

ppc4xx: Enable Primordial Stack for 40x and Unify ECC Handling

2008-06-03T18:20:50+00:00

This patch (Part 1 of 2):

* Rolls up a suite of changes to enable correct primordial stack and
  global data handling when the data cache is used for such a purpose
  for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).

* Related to the first, unifies DDR2 SDRAM and ECC initialization by
  eliminating redundant ECC initialization implementations and moving
  redundant SDRAM initialization out of board code into shared 4xx
  code.

* Enables MCSR visibility on the 405EX(r).

* Enables the use of the data cache for initial RAM on
  both AMCC's Kilauea and Makalu and removes a redundant
  CFG_POST_MEMORY flag from each board's CONFIG_POST value.

  - Removed, per Stefan Roese's request, defunct memory.c file for
    Makalu and rolled sdram_init from it into makalu.c.

With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

Big white-space cleanup.

2008-05-20T22:14:08+00:00

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

ppc4xx: 405EX: Correctly enable USB pins

2007-12-08T13:47:34+00:00

This patch selects the USB data pins in the 405EX GPIO and MFC (multi
function control) registers. This is done for the AMCC Kilauea and
Makalu eval boards.

ppc4xx: Enable 440 GPIO init table CFG_440_GPIO_TABLE for 405 platforms

2007-11-15T13:23:55+00:00

- Rename CFG_440_GPIO_TABLE to CFG_4xx_GPIO_TABLE
- Cleanup of the 4xx GPIO functions
- Move some GPIO defines from the cpu headers ppc405.h/ppc440.h into gpio.h

ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xx

2007-10-31T20:20:50+00:00

This patch moves some common 4xx macros and the PPC405_SYS_INFO/
PPC440_SYS_INFO structure into the common ppc4xx.h header.

Lot's of other macros are good candidates to be consolidated this way
in the future.
