* [ppc440SPe] Graceful recovery from machine check during PCIe configurationGrzegorz Bernacki2007-08-02-9/+57
| | | | | | | | | | | During config transactions on the PCIe bus an attempt to scan for a non-existent device can lead to a machine check exception with certain peripheral devices. In order to avoid crashing in such scenarios the instrumented versions of the config cycle read routines are introduced, so the exceptions fixups framework can gracefully recover.

* [ppc4xx] Separate settings for PCIe bus numbering on 440SPe rev.ARafal Jaworowski2007-08-02-3/+8
| | | | | | | | | This brings back separate settings for PCIe bus numbers depending on chip revision, which got eliminated in 2b393b0f0af8402ef43b25c1968bfd29714ddffa commit. 440SPe rev. A does NOT work properly with the same settings as for the rev. B (no devices are seen on the bus during enumeration). Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

| | | | | | | | | | | | | | | | | | | | The new function remove_tlb() can be used to remove the TLB's used to map a specific memory region. This is especially useful for the DDR(2) setup routines which configure the SDRAM area temporarily as a cached area (for speedup on auto-calibration and ECC generation) and later need this area uncached for normal usage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for calling a plattform dependant pci_pre_init() function for 405 boards. This can be used to move the current pci_405gp_fixup_irq() function into the board code. This patch also makes the CFG_PCI_PRE_INIT define obsolete. A default function with 'weak' attribute is used when a board specific pci_pre_init() is not implemented. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>

Please make sure to configure jumper J7 to position 2-3 when booting from NOR, and to position 1-2 when booting for NAND. I also added a board command to configure the I2C bootstrap EEPROM values. Right now only 267MHz is support for booting either via NOR or NAND FLASH.

| | | | | | | | | | | | | | | | | | | | 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>

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.
