2010-07-26powerpc/8xxx: Enable DDR3 RDIMM supportyork
Enabled registered DIMMs using data from SPD. RDIMMs have registers which need to be configured before using. The register configuration words are stored in SPD byte 60~116 (JEDEC standard No.21-C).

2010-07-26powerpc/p4080: Add support for initializing SERDESKumar Gala
Add support for initializing the SERDES blocks on CoreNet style QoriQ devices and the p4080 specific SERDES tables to know which actual componetns are enabled. Additionally, split out the Frame Manger (FMAN) into its specific ethernet ports instead of gross level of the full FMAN.

2010-07-26fdt: Add function to alloc phandle valuesKumar Gala
If we are creating reference (handles) to nodes in a device tree we need to first create a new phandle in node and this needs a new phandle value. So we search through the whole dtb to find the max phandle value and return the next greater value for a new phandle allocation.

2010-07-24usb_storage.c: change progress output in debug() messageWolfgang Denk
The dots printed by common/usb_storage.c as progress meter corrupt the output for example of "fatls usb" commands like this: => fatls usb 0 . <<==== here 29 file.001 29 file.002 29 file.003 29 file.004 29 file.005 29 file.006 29 file.007 29 file.008 29 file.009 29 file.010 29 file.011 29 file.012 29 file.013 29 file.014 29 file.015 29 file.016 . <<==== here 29 file.017 29 file.018 29 file.019 ...

2010-07-24FAT32: fix broken root directory handling.Wolfgang Denk
On FAT32, instead of fetching the cluster numbers from the FAT, the code assumed (incorrectly) that the clusters for the root directory were allocated contiguously. In the result, only the first cluster could be accessed. At the typical cluster size of 8 sectors this caused all accesses to files after the first 128 entries to fail - "fatls" would terminate after 128 files (usually displaying a bogus file name, occasionally even crashing the system), and "fatload" would fail to find any files that were not in the first directory cluster. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-07-24FAT32: fix support for superfloppy-format (PBR)Wolfgang Denk
"Superfloppy" format (in U-Boot called PBR) did not work for FAT32 as the file system type string is at a different location. Add support for FAT32. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-07-24usb_storage.c: initialize device typeWolfgang Denk
The device type was left uninitialized which caused later tests against DEV_TYPE_UNKNOWN to fail. In the result, "usb part" would attempt to print information about non-existent devices like this: => usb part print_part of 0 Partition Map for USB device 0 -- Partition Type: DOS Partition Start Sector Num Sectors Type 1 0 2031616 f8 print_part of 1 ## Unknown partition table print_part of 2 ## Unknown partition table print_part of 3 ## Unknown partition table print_part of 4 ## Unknown partition table => By initializing the type as DEV_TYPE_UNKNOWN we avoid all the "Unknown partition table" messages. [Note: the "print_part of ?" messages is left over debug code that will be removed in another patch.] Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Remy Bohmer <linux@bohmer.net>
2010-07-24cmd_usage(): simplify return code handlingWolfgang Denk
Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too. Signed-off-by: Wolfgang Denk <wd@denx.de>

2010-07-23ppc4xx: Add ECC status info to machine-check exception for IBM DDR2 coreStefan Roese
Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: Add "ecctest" command to test/simulate ECC errorsStefan Roese
This patch adds the "ecctest" command to test and simulate ECC errors (single bit and/or double bit) while running from SDRAM. Currently only the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT). This is done by copying and calling functions, modifying the SDRAM controller operation mode, in internal SRAM/OCM. For correctable ECC errors (single bit) only the status will be printed since the DDR2 controller doesn't provide the faulting address: => ecctest 1000000 1 Using address 01000000 for 1 bit ECC error injection ECC: Correctable error Uncorrectable ECC errors (double bit) will also display the faulting address: => ecctest 1000000 2 Using address 01000000 for 2 bit ECC error injection ECC: Uncorrectable error at 0x0001000000 To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST in the board config header. Tested on katmai and t3corp. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: DDR/ECC: Use correct macros to clear error statusStefan Roese
Use the correct macro instead of the hardcoded 0x4c to clear the ECC status in the 440/460 DDR(2) error status register after ECC initialization. Also the non-440 parts (405EX(r) right now) and the IBM DDR PPC variants (440GX) use a different registers to clear this error status. Use the correct ones. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: Only define DDR2 registers for the correct PowerPC variantsStefan Roese
Make sure that some SDRAM/DDR2 registers are only defined for the PPC variants really implementing those registers. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: Add CONFIG_DDR_RFDC_FIXED to allow board specific RFDC valuesStefan Roese
Using this define, a board can define an opimized RFDC value and use the auto calibration code to "tune" the remaining DDR2 controller calibration register. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: T3CORP fixes and updatesStefan Roese
This patch fixes some problems for the T3CORP board. Here the list of the changes: - Add 600-67 and 677 CPU frequency setting to chip_config command - Define CONFIG_DDR_RFDC_FIXED on t3corp: While using the "normal" auto calibration code, sometimes values for RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang upon relocation, while running from SDRAM). With this optimized RFDC value we can force this register and use the auto-calibration code to setup the remaining calibration registers. - Increase sizes of FPGA chips selects - EBC timing updated OEN=3 for 66 MHz EBC speed - Change ext. IRQ2 setup to level-low active - Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the chip busy status. This is now used instead of the data toggle method which is used historically by default in the common CFI driver. With this change a problem with not written data is solved on this board, where a 32 byte block of data is still erased instead of filled with the correct content after these commands: => erase 0xfc100000 +0x1000000 .................................................................... done Erased 128 sectors => cp.b 0x100000 0xfc100000 0x1000000 Copy to Flash... done => cmp.b 0x100000 0xfc100000 0x1000000 byte at 0x00d0d6c0 (0x00) != byte at 0xfcd0d6c0 (0xff) Total of 12637888 bytes were the same Signed-off-by: Stefan Roese <sr@denx.de>

2010-07-22i2c: soft_i2c: add simple GPIO implementationMike Frysinger

2010-07-20powerpc/85xx & 86xx: Rework ft_fsl_pci_setup to not require aliasesKumar Gala
Previously we used an alias the pci node to determine which node to fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to find the node to update. Additionally, we replace the code in each board with a single macro call that makes assumes uniform naming and reduces duplication in this area. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-20fdt: Add fdt_node_offset_by_compat_reg helperKumar Gala
Given a compatible string and physical address try and find a node that matches. This is useful when we want to find a specific device node to update (for example if we have multiple PCI nodes we can use the physical address to distinguish them when trying to update the device tree).

2010-07-20fdt: Add fdt_translate_address to convert reg node to cpu phys addrKumar Gala
This code is extracted out of the Linux Kernel code from arch/powerpc/kernel/prom_parse.c. We maintain some of the same structure to support multiple bus types even though we only have one in the current code. In the future we might want to translate across a PCI bus and thus it will be easier to add that functionality back in.
