2008-03-15ppc4xx: Add Canyonlands NAND booting supportStefan Roese
460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>

2008-01-09ppc4xx: Add 44x cache locking to better support init-ram in d-cacheStefan Roese
This patch adds support for locking the init-ram/stack in d-cache, so that other regions may use d-cache as well Note, that this current implementation locks exactly 4k of d-cache, so please make sure that you don't define a bigger init-ram area. Take a look at the lwmon5 440EPx implementation as a reference. Signed-off-by: Stefan Roese <sr@denx.de>

2007-06-19[ppc4xx] Fix problem with NAND booting on AMCC AcadiaStefan Roese

2007-06-15ppc4xx: Clean up 440 exceptions handlingGrzegorz Bernacki
- 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>
2007-06-06ppc4xx: Add NAND booting support for AMCC Acadia (405EZ) eval boardStefan Roese
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>

2007-06-01ppc4xx: Add NAND booting support for AMCC Bamboo (440EP) eval boardStefan Roese
This patch adds NAND booting support for the AMCC Bamboo eval board. Since the NAND-SPL boot image is limited to 4kbytes, this version only supports the onboard 64MBytes of DDR. The DIMM modules can't be supported, since the setup code for I2C DIMM autodetection and configuration is too big for this NAND bootloader. Signed-off-by: Stefan Roese <sr@denx.de>

2007-03-08[PATCH] Update AMCC Luan 440SP eval board supportStefan Roese
The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR inititializition. This includes DDR auto calibration and support for different DIMM modules, instead of the fixed setup used in the earlier version. This patch also enables the cache in FLASH for the startup phase of U-Boot (while running from FLASH). After relocating to SDRAM the cache is disabled again. This will speed up the boot process, especially the SDRAM setup, since there are some loops for memory testing (auto calibration). Signed-off-by: Stefan Roese <sr@denx.de>
