* ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1Stefan Roese2008-06-03-414/+0
| | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-13/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Wolfgang Denk2008-05-21-863/+863
| | | | | | | | | | | 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. Signed-off-by: Wolfgang Denk <wd@denx.de>

* ppc4xx: Clean up 440 exceptions handlingGrzegorz Bernacki2007-06-15-0/+9
| | | | | | | | | | | | | | | | | | | | | | - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com> Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add NAND booting support for AMCC Acadia (405EZ) eval boardStefan Roese2007-06-06-0/+8
| | | | | | | | | | | | | | | | This patch adds NAND booting support for the AMCC Acadia eval board. Please make sure to configure jumper J7 to position 2-3 when booting from NOR, and to position 1-2 when booting for NAND. I also added a board command to configure the I2C bootstrap EEPROM values. Right now only 267MHz is support for booting either via NOR or NAND FLASH. Here the usage: => bootstrap 267 nor ;to configure the board for 267MHz NOR booting => bootstrap 267 nand ;to configure the board for 267MHz NNAND booting Signed-off-by: Stefan Roese <sr@denx.de>
