2010-07-25Blackfin: jtag-console: add debug markersMike Frysinger
While we're in here, add some useful debug points. We need custom debug statements because we need the output to only go to the serial port. If we used the standard debug helpers, the output would also go to the stdout (which would be the jtag console) and make it hard to figure out what is going where exactly.

2010-07-25Blackfin: jtag-console: robustify against missing peerMike Frysinger
If the other side isn't listening, we should reset the state to ignore the whole message and not just the part we missed. This makes it easier to connect at any time to the jtag console without worrying about the two sides getting out of sync and thus sending garbage back and forth.

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>
2010-07-21powerpc/85xx: Rework P1022 SERDES is_serdes_configured supportKumar Gala
Move serdes init until after we are in ram so we can keep track of a global static protocal map for the particular serdes config we are in. This makes is_serdes_configured() much simplier and not constantly reading registers to determine if a given device is enabled based on the protocol.

On QorIQ CoreNet based devices we have a global clocking block. We want to keep track of SYSCLK frequency as it is what is used to derive all other frequencies in the SoC Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-20powerpc/85xx: Use fdt_node_offset_by_compat_reg for clock-frequency updatesKumar Gala
Move to using fdt_node_offset_by_compat_reg to find the node offsets we want to update instead of using aliases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
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>
2010-07-20powerpc/86xx: Move PCI/PCIe address defines into common immap_86xx.hKumar Gala

2010-07-16powerpc/85xx: Move p1022ds slot code into board fileKumar Gala

2010-07-16fsl: add LAW target to fsl_pci_info structureTimur Tabi
Add the LAW target (enum law_trgt_if) to the fsl_pci_info structure, so that we can capture the LAW target for a given PCI or PCIE controller. Also update the SET_STD_PCI_INFO and SET_STD_PCIE_INFO macros to assign the LAW_TRGT_IF_PCI[E]_x macro to the LAW target field of the structure. This will allow future PCI[E] code to configure the LAW target automatically, rather than requiring each board to it for each PCI controller separately.

2010-07-16powerpc/85xx: Add support for link stack & STAC on e5500Kumar Gala

2010-07-16mpc85xx: tlb.c cleanupsBecky Bruce
Extract the operation to read a tlb into a function - we will need this later to print out the tlbs, and there's no point in duplicating the code. Create a TSIZE_TO_BYTES macro to deal with the conversion from the MAS field to an actual size instead of duplicating this in code. There are a few misc other minor cleanups.

2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.
