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>
2007-06-01NAND: Add hardware ECC support to the PPC4xx NAND driver ndfc.cStefan Roese
This patch adds hardware ECC support to the NDFC driver. It also changes the register access from using the "simple" in32/out32 functions to the in_be32/out_be32 functions, which make sure that the access is correctly synced. This is the only recommended access to SoC registers in the current Linux kernel. Signed-off-by: Stefan Roese <sr@denx.de>

2007-04-18ppc4xx: Add output for bootrom location to 405EZ portsStefan Roese
Now 405EZ ports also show upon bootup from which boot device they are configured to boot: U-Boot 1.2.0-gd3832e8f-dirty (Apr 18 2007 - 07:47:05) CPU: AMCC PowerPC 405EZ Rev. A at 199.999 MHz (PLB=133, OPB=66, EBC=66 MHz) Bootstrap Option E - Boot ROM Location EBC (32 bits) 16 kB I-Cache 16 kB D-Cache Board: Acadia - AMCC PPC405EZ Evaluation Board Signed-off-by: Stefan Roese <sr@denx.de>
2007-04-12ppc4xx: Fix i2c divisor calcularion for PPC4xxJeffrey Mann
This patch fixes changes the i2c_init(...) function to use the function get_OPB_freq() rather than calculating the OPB speed by sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is specific per processor. The prior method was not and so was calculating the wrong speed for some PPC4xx processors.

2007-03-31ppc4xx: Update 44x_spd_ddr2 code (440SP/440SPe)Stefan Roese
Fix a bug in the auto calibration routine. This driver now runs more reliable with the tested modules. It's also tested with 167MHz PLB frequency (667MHz DDR2 frequency) on the Katmai. Signed-off-by: Stefan Roese <sr@denx.de>

This patch adds support for the new AMCC 405EZ PPC. It is in preparation for the AMCC Acadia board support. Please note that this Acadia/405EZ support is still in a beta stage. Still lot's of cleanup needed but we need a preliminary release now. 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>

2007-03-07[PATCH] Fix AMCC 44x SPD SDRAM init code to support 2 DIMM'sStefan Roese
This patch fixes a problem that occurs when 2 DIMM's are used. This problem was first spotted and fixed by Gerald Jackson <gerald.jackson@reaonixsecurity.com> but this patch fixes the problem in a little more clever way. This patch also adds the nice functionality to dynamically create the TLB entries for the SDRAM (tlb.c). So we should never run into such problems with wrong (too short) TLB initialization again on these platforms. As this feature is new to the "old" 44x SPD DDR driver, it has to be enabled via the CONFIG_PROG_SDRAM_TLB define. Signed-off-by: Stefan Roese <sr@denx.de>

2007-03-01[PATCH] Update AMCC Katmai 440SPe eval board supportStefan Roese
This patch updates the recently added Katmai board support. The biggest change is the support of ECC DIMM modules in the 440SP(e) SPD DDR2 driver. Please note, that still some problems are left with some memory configurations. See the driver for more details. Signed-off-by: Stefan Roese <sr@denx.de>

2007-02-20[PATCH] PPC4xx: Add 440SP(e) DDR2 SPD DIMM supportStefan Roese
This patch adds support for the DDR2 controller used on the 440SP and 440SPe. It is tested on the Katmai (440SPe) eval board and works fine with the following DIMM modules: - Corsair CM2X512-5400C4 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM) This patch also adds the nice functionality to dynamically create the TLB entries for the SDRAM (tlb.c). So we should never run into such problems with wrong (too short) TLB initialization again on these platforms. Signed-off-by: Stefan Roese <sr@denx.de>
2007-02-20[PATCH] PPC4xx: Split 4xx SPD SDRAM init routines into 2 filesStefan Roese
Since the existing 4xx SPD SDRAM initialization routines for the 405 SDRAM controller and the 440 DDR controller don't have much in common this patch splits both drivers into different files. This is in preparation for the 440 DDR2 controller support (440SP/e). Signed-off-by: Stefan Roese <sr@denx.de>
2007-02-20[PATCH] PPC4xx: Add support for multiple I2C bussesStefan Roese
This patch adds support for multiple I2C busses on the PPC4xx platforms. Define CONFIG_I2C_MULTI_BUS in the board config file to make use of this feature. It also merges the 405 and 440 i2c header files into one common file 4xx_i2c.h. Also the 4xx i2c reset procedure is reworked since I experienced some problems with the first access on the 440SPe Katmai board. Signed-off-by: Stefan Roese <sr@denx.de>
2007-02-02[PATCH] Correctly display PCI arbiter en-/disabled on some 4xx boardsStefan Roese
