* ppc4xx: Enable ECC on LWMON5Stefan Roese2008-03-27-70/+20
| | | | | | | | | | | Since all ECC related problems seem to be resolved on LWMON5, this patch now enables ECC support. We have to write the ECC bytes by zeroing and flushing in smaller steps, since the whole 256MByte takes too long for the external watchdog. Signed-off-by: Stefan Roese <sr@denx.de>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>

| * ppc4xx: Change LWMON5 to not use OCM for init-ram and POST anymoreStefan Roese2008-01-09-1/+1
| | | | | | | | | | | | | | This patch configures the LWMON5 port to use d-cache as init-ram and the unused GPT0_COMP6 as POST WORD storage. Signed-off-by: Stefan Roese <sr@denx.de>
* | PPC4xx: Remove sdram.h from board/lwmon5Larry Johnson2008-01-04-505/+0

* | PPC4xx: Use common code for LWMON5 board SDRAM supportLarry Johnson2008-01-04-337/+20

* Add definitions for 440EPx/GRx SDRAM controller to ppc440.hLarry Johnson2007-12-27-2/+2
| | | | | | | | | This patch adds the Denali SDRAM controller definitions to "ppc440.h". It also fixes two typos in the definitions, so the board-specific "sdram.h" files containing these definitions are also fixed to avoid compiler warnings. Signed-off-by: Larry Johnson <lrj@acm.org>

* | 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>
* ppc4xx: Add support for 2nd I2C EEPROM on lwmon5 boardStefan Roese2007-08-23-0/+27
| | | | | | | | | | | This patch adds support for the 2nd EEPROM (AT24C128) on the lwmon5 board. Now the "eeprom" command can be used to read/write from/to this device. Additionally a new command was added "eepromwp" to en-/disable the write-protect of this 2nd EEPROM. The 1st EEPROM is not affected by this write-protect command.

| | | | | | | | | | | | | | | | | | | | | | | | 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: Add matrix kbd support to lwmon5 board (440EPx based)Stefan Roese2007-08-21-13/+466
|/ | | | | | | | | This patch adds support for the matrix keyboard on the lwmon5 board. Since the implementation in the dsPCI is kind of compatible with the "old" lwmon board, most of the code is copied from the lwmon board directory. Signed-off-by: Stefan Roese <sr@denx.de>
