* NAND: Rename DEBUG to MTDDEBUG to avoid namespace pollution.Scott Wood2008-07-09-3/+7
| | | | | | | | | This is particularly problematic now that non-NAND-specific code is including <nand.h>, and thus all debugging code is being compiled regardless of whether it was requested, as reported by Scott McNutt <smcnutt@psyent.com>. Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During 83xx setup the "System I/O configuration register high" gets overwritten with user defined value if CFG_SICRH is defined. Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH must keep their reset value regardless of configuration. On my board (using RGMII) those bits are set after reset - yet it's unclear where they come from. The patch keeps both bits on MPC834x and MPC8313.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-5/+5
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code.

| * | ppc4xx: Remove superfluous dram_init() call or replace it by initdram()Stefan Roese2008-06-03-8/+8

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 <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the common 4xx ECC code really usable on 440GP style platforms. Since the IBM DDR controller used on 440GP/GX/EP/GR is not register compatible to the IBM DDR/2 controller used on 405EX/440SP/SPe/460EX/GT we need to make some processor dependant defines used later on by the driver.

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/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.SStefan Roese2008-06-03-126/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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[].

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.
