2009-11-19ppc4xx: Consolidate pci_master_init() functionStefan Roese
This patch removes the duplicted implementations of the pci_master_init() function by introducing a weak default function for it. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
2009-11-19ppc4xx: Consolidate pci_pre_init() functionStefan Roese
This patch removes the duplicted implementations of the pci_pre_init() function by introducing a weak default function for it. This weak default has a different implementation for some PPC variants. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
2009-11-19ppc4xx: Consolidate pci_target_init() functionStefan Roese
This patch removes the duplicted implementations of the pci_target_init() function by introducing a weak default function for it. This weak default has a different implementation for 440EP(x)/GR(x) PPC's. It can be overridden by a board specific version (e.g. PMC440, korat).

2009-11-04fsl_pci_init_port end-point initialization is brokenEd Swarthout
commit 70ed869e broke fsl pcie end-point initialization. Returning 0 is not correct. The function must return the first free bus number for the next controller. fsl_pci_init() must still be called and a bus allocated even if the controller is an end-point.

2009-11-04Revert "ppc/85xx/pci: fsl_pci_init: pcie agent mode support"Kumar Gala
This reverts commit 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc. There isn't any need to modify the API for fsl_pci_init_port to pass the status of host/agent(end-point) status. We can determine that internally to fsl_pci_init_port. Revert the patch that makes the API change. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-10-2785xx: MP Boot Page Translation updatePeter Tyser
This change has 3 goals: - Have secondary cores be released into spin loops at their 'true' address in SDRAM. Previously, secondary cores were put into spin loops in the 0xfffffxxx address range which required that boot page translation was always enabled while cores were in their spin loops. - Allow the TLB window that the primary core uses to access the secondary cores boot page to be placed at any address. Previously, a TLB window at 0xfffff000 was always used to access the seconary cores' boot page. This TLB address requirement overlapped with other peripherals on some boards (eg XPedite5370). By default, the boot page TLB will still use the 0xfffffxxx address range, but this can be overridden on a board-by-board basis by defining a custom CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page remains in use while U-Boot executes. Previously it was only temporarily used, then restored to its initial value. - Allow Boot Page Translation to be disabled on bootup. Previously, Boot Page Translation was always left enabled after secondary cores were brought out of reset. This caused the 0xfffffxxx address range to somewhat "magically" be translated to an address in SDRAM. Some boards may not want this oddity in their memory map, so defining CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after the secondary cores are initialized. These changes are only applicable to 85xx boards with CONFIG_MP defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-10-08mpc512x: fix fixed_sdram() init code.Wolfgang Denk
Commit 054197ba and later fixes used an array to initialize some of the MDDRC parameters; however, the use of an array turned out to be a bad idea as it was not possible to correlate structure entries to array indices in readable and reliable way. Now we use a struct instead, which makes this self-explanatory. Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-10-07ppc4xx: Add PPC405EX(r) Rev D supportStefan Roese
Unfortunately some Rev D PPC405EX/405EXr PVR's are identical with older 405EX(r) parts. Here a list: 0x12911475 - 405EX Rev D with Security *and* 405EX Rev A/B witout Sec 0x12911473 - 405EX Rev D without Security *and* 405EXr Rev A/B with Sec Since there are only a few older parts in the field, this patch now changes the PVR's above to represent the new Rev D versions.

2009-10-03ppc: Remove reloc_off field from global_data structurePeter Tyser
Now that proper relocation is supported, the reloc_off field is no longer necessary. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We therefore increment XF_VERSION to 6 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-10-03ppc: Enable full relocation to RAMPeter Tyser
The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

2009-10-02ppc4xx: Merge PPC4xx DDR and DDR2 ECC handlingStefan Roese
This patch merges the ECC handling (ECC parity byte writing) into one file (ecc.c) for all PPC4xx SDRAM controllers except for PPC440EPx/GRx. This exception is because only those PPC's use the completely different Denali SDRAM controller core. Previously we had two routines to generate/write the ECC parity bytes. With this patch we now only have one core function left. Tested on Kilauea (no ECC) and Katmai (with and without ECC).

2009-09-24ppc/p4080: Add support for CoreNet style platform LAWsKumar Gala
On CoreNet based platforms the LAW address is split between an high & low register and we no longer shift the address. Also, the target IDs on CoreNet platforms have been completely re-assigned. Additionally, added a new find_law() API to which LAW an address hits in. This is need for the CoreNet style boot release code since it will need to determine what the target ID should be set to for boot window translation. Finally, enamed LAWAR_EN to LAW_EN and moved to header so we can use it elsewhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-24ppc/p4080: Add p4080 platform immap definitionsKumar Gala
The p4080 SoC has a significant amount of commonality with the 85xx/PQ3 platform. We reuse the 85xx immap and just add new definitions for local access and global utils. The global utils is now broken into global utils, clocking and run control/power management. The offsets from CCSR for a number of blocks have also changed. We introduce the CONFIG_FSL_CORENET define to distinquish the PQ3 style of platform from the new p4080 platform. We don't use QoirQ as there are products (like p2020) that are PQ3 based platforms but have the QoirQ name. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-09-24ppc/85xx: Fix LCRR_CLKDIV definesKumar Gala
For some reason the CLKDIV field varies between SoC in how it interprets the bit values. All 83xx and early (e500v1) PQ3 devices support: clk/2: CLKDIV = 2 clk/4: CLKDIV = 4 clk/8: CLKDIV = 8 Newer PQ3 (e500v2) and MPC86xx support: clk/4: CLKDIV = 2 clk/8: CLKDIV = 4 clk/16: CLKDIV = 8 Ensure that the MPC86xx and MPC85xx still get the same behavior and make the defines reflect their logical view (not the value of the field).

2009-09-08ppc/8xxx: Refactor code to determine if PCI is enabled & agent/hostKumar Gala
Refactor the code into a simple bitmask lookup table that determines if a given PCI controller is enabled and if its in host/root-complex or agent/end-point mode. Each processor in the PQ3/MPC86xx family specified different encodings for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-08ppc/85xx: Add a simple function to search the TLBKumar Gala
Allow us to search the TLB array based on an address. This is useful if we want to change an entry but dont know where it happens to be located. For example, the boot page mapping we use on MP or the flash TLB that we change the WIMGE settings for after we've relocated. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-0885xx: Add support for setting IVORs to fixed offset defaultsKumar Gala
In future Book-E implementations IVORs will most likely go away and be replaced with fixed offsets. The IVPR will continue to exist to allow for relocation of the interrupt vectors. This code adds support to setup the IVORs as their fixed offset values per the ISA 2.06 spec when we transition from u-boot to another OS either via 'bootm' or a cpu release.
