* ppc4xx: 4xx_pcie: Change CFG_PCIE_MEMSIZE to 128MB on Yucca & KatmaiStefan Roese2007-10-31-1/+24
| | | | | | | | | | | | | | | | | 128MB seems to be the smallest possible value for the memory size for on PCIe port. With this change now the BAR's of the PCIe cards are accessible under U-Boot. One big note: This only works for PCIe port 0 & 1. For port 2 this currently doesn't work, since the base address is now 0xc0000000 (0xb0000000 + 2 * 0x08000000), and this is already occupied by CFG_PCIE0_CFGBASE. But solving this issue for port 2 would mean to change the base addresses completely and this change would have too much impact right now. This patch adds debug output to the 4xx pcie driver too.

| | | | | | | | These files were introduced with the IBM 405GP but are currently used on all 4xx PPC platforms. So the name doesn't match the content anymore. This patch renames the files to 4xx_pci.c/h. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (3)Stefan Roese2007-10-31-419/+223
| | | | | | | | | | | | | | | (3) This patch introduces macros like SDRN_PESDR_DLPSET(port) to access the SDR registers of the PCIe ports. This makes the overall design clearer, since it removed a lot of switch statements which are not needed anymore. Also, the functions ppc4xx_init_pcie_rootport() and ppc4xx_init_pcie_entport() are merged into a single function ppc4xx_init_pcie_port(), since most of the code was duplicated. This makes maintainance and porting to other 4xx platforms easier. Signed-off-by: Stefan Roese <sr@denx.de>

* [PPC440SPe] Improve PCIe configuration space accessGrzegorz Bernacki2007-09-07-31/+97
| | | | | | | | | | | | | - correct configuration space mapping - correct bus numbering - better access to config space Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the first device on the first bus. We now allow to configure up to 16 buses; also, scanning for devices behind the PCIe-PCIe bridge is supported, so peripheral devices farther in hierarchy can be identified.

* [PPC440SPe] Convert machine check exceptions handlingGrzegorz Bernacki2007-09-07-44/+37
| | | | | | | | | | | | | | | | Convert using fixup mechanism to suppressing MCK for the duration of config read/write transaction: while fixups work fine with the case of a precise exception, we identified a major drawback with this approach when there's an imprecise case. In this scenario there is the following race condition: the fixup is (by design) set to catch the instruction following the one actually causing the exception; if an interrupt (e.g. decrementer) happens between those two instructions, the ISR code is executed before the fixup handler the machine check is no longer protected by the fixup handler as it appears as within the ISR code. In consequence the fixup approach is being phased out and replaced with explicit suppressing of MCK during a PCIe config read/write cycle. Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
