* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | 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. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* ppc4xx: Remove superfluous dram_init() call or replace it by initdram()Stefan Roese2008-06-03-24/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sr@denx.de>
* ppc4xx: Complete remove bogus dflush()Stefan Roese2008-04-29-3/+3
| | | | | | | | | | Since the current dflush() implementation is know to have some problems (as seem on lwmon5 ECC init) this patch removes it completely and replaces it by using clean_dcache_range(). Tested on Katmai with ECC DIMM. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: program_tlb now uses 64bit physical addessStefan Roese2008-03-15-2/+0
| | | | | | | | This patch changes the physical addess parameter from 32bit to 64bit. This is needed for 36bit 4xx platforms to access areas located beyond the 4GB border, like SoC peripherals (EBC etc.). Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: HCU4/5. CleanupsNiklaus Giger2008-02-16-13/+19
| | | | | | | | | | | - Fix some coding style violations. - Use in/out_u16/32 where appropriate. - Use register names from ppc405.h. - Fix trace useage for Lauterbach. - Remove obsolete generation HCU2. - Renamed fixed_hcu4_sdram to init_ppc405_sdram.

| | | | | | | | | | - Moved some common code to nestal/common/nm_bsp.c. - Added support for the vxWorks EDR. - Enable trace for Lauterbach, if present. - Added support for POST. - Stylistic cleanups (multi-line comments/ enforce 80 colomn width) Signed-off-by: Niklaus Giger <niklaus.giger@netstal.com>
* ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese2007-10-31-1/+1
| | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>

| * lib_ppc: make board_add_ram_info weakKim Phillips2007-08-18-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | platforms wishing to display RAM diagnostics in addition to size, can do so, on one line, in their own board_add_ram_info() implementation. this consequently eliminates CONFIG_ADD_RAM_INFO.

* | PPC4xx:HCU4/5 cleanup ecc/sdram initNiklaus Giger2007-08-16-3/+12
|/ | | | | | | | | | Make ecc initialisation robust, as DDR2-ECC errors may be generated while zeroing the RAM. Return 16 bytes (a cacheline) less than the available memory, as the board and/or PPC440EPx might have problems accessing the last bytes. Signed-off-by: Niklaus Giger <niklaus.giger@netstal.com>
