ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initialization

2008-11-21T10:02:04Z

Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM. Adjusted internal SRAM initialization to match updated user manual recommendation. OCM & ISRAM are now mapped as follows: physical virtual size ISRAM 0x4_0000_0000 0xE300_0000 256k OCM 0x4_0004_0000 0xE304_0000 64k A single TLB was used for this mapping.

ppc4xx: Added ppc4xx-isram.h for internal SRAM and L2 cache DCRs

2008-11-21T09:52:33Z

Added include/asm-ppc/ppc4xx-isram.h and moved internal SRAM and L2 cache DCRs from ppc440.h to this new header. Also converted these DCR defines from lowercase to uppercase and modified referencing modules to use them. Signed-off-by: Dave Mitchell Signed-off-by: Stefan Roese

ppc4xx: Clear all potentially pending exceptions in MCSR

2008-11-20T10:48:53Z

This is needed on Canyonlands which still has an exception pending while running relocate_code(). This leads to a failure after trap_init() is moved to the top of board_init_r(). Signed-off-by: Stefan Roese

ppc4xx: Generic architecture for xilinx ppc405(v3)

2008-10-24T15:26:09Z

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Stefan Roese

ppc4xx: Remove superfluous dram_init() call or replace it by initdram()

2008-06-03T18:22:19Z

Historically the 405 U-Boot port had a dram_init() call in early init stage. This function was still called from start.S and most of the time coded in assembler. This is not needed anymore (since a long time) and boards should implement the common initdram() function in C instead. This patch now removed the dram_init() call from start.S and removes the empty implementations that are scattered through most of the 405 board ports. Some older board ports really implement this dram_init() though. These are: csb272 csb472 ERIC EXBITGEN W7OLMC W7OLMG I changed those boards to call this assembler dram_init() function now from their board specific initdram() instead. This *should* work, but please test again on those platforms. And it is perhaps a good idea that those boards use some common 405 SDRAM initialization code from cpu/ppc4xx at some time. So further patches welcome here. Signed-off-by: Stefan Roese

ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.S

2008-06-03T18:21:49Z

This patch consolidates the 405 and 440 parts of the NAND booting code selected via CONFIG_NAND_SPL. Now common code is used to initialize the SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc. Only *after* running from this location, nand_boot() is called. Please note that the initsdram() call is now moved from nand_boot.c to start.S. I experienced problems with some boards like Kilauea (405EX), which don't have internal SRAM (OCM) and relocation needs to be done to SDRAM before the NAND controller can get accessed. When initdram() is called later on in nand_boot(), this can lead to problems with variables in the bss sections like nand_ecc_pos[]. Signed-off-by: Stefan Roese Acked-by: Scott Wood
