* ppc4xx: Add Canyonlands NAND booting supportStefan Roese2008-03-15-1/+7
| | | | | | | | | | | | | | | 460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: interrupt.c reworkedStefan Roese2008-03-15-448/+141
| | | | | | | | This patch is a rework of the 4xx interrupt handling done while adding the 460EX/GT support. Interrupts are needed on 4xx for the EMAC driver. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | This patch changes the physical addess parameter from 32bit to 64bit. This is needed for 36bit 4xx platforms to access areas located beyond the 4GB border, like SoC peripherals (EBC etc.). Signed-off-by: Stefan Roese <sr@denx.de>

* PPC4xx (Sequoia): Fix Ethernet "remote fault" problemsMike Nuss2008-03-04-3/+2
| | | | | | | | | | | | | | Every now and then a Sequoia board (or equivalent hardware) had problems connecting to a Gigabit capable network interface. There were differences in the PHY setup between Linux and U-Boot. This patch fixes the problem. Apparently "remote fault" is being set, which signals to some devices (on the other end of the cable) that a fault has occurred, while other devices ignore it. I believe the RF bit was causing the issue, but I removed T4 also, to match up with Linux. Signed-off-by: Mike Nuss <mike@terascala.com>
* ppc4xx: EMAC: Fix 405EZ fifo size setup in EMAC_MR1Stefan Roese2008-03-02-2/+3
| | | | | | | | | The 405EZ only supports 512 bytes of rx-/tx-fifo EMAC sizes. But currently 4k/2k is configured. This patch fixes this issue. Thanks to Thomas Kindler <tkindler@lenord.de> for pointing this out. Signed-off-by: Stefan Roese <sr@denx.de>

| * 85xx: Don't icbi when unlocking the cacheKumar Gala2008-02-27-5/+2
| | | | | | | | | | | | | | | | | | There is no reason to icbi when invalidating the temporary stack in the d-cache. Its impossible on e500 to have the i-cache contain any addresses in the temp stack and it can be problematic in generating transactions on the bus to non-valid addresses.

| * Fix source for ECM error IVPRAndy Fleming2008-02-27-1/+1

| * Invalidate INIT_RAM TLB mappingsAndy Fleming2008-02-27-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0db37dc... (and some others) changed the INIT_RAM TLB mappings to be unguarded. This collided with an existing "bug" where the mappings for the INIT_RAM were being kept around. This meant that speculative loads to those addresses were succeeding in the TLB, and going out to the bus, where they were causing an exception (there's nothing at that address). The Flash code was coincidentally causing such a speculative load. Rather than go back to mapping the INIT RAM as guarded, we fix it so that the entries for the INIT_RAM are invalidated. Thus the speculative loads will fail in the TLB, and have no effect. Signed-off-by: Andy Fleming <afleming@freescale.com>

| * 86xx: Convert sbc8641d to use libfdt.Jon Loeliger2008-02-18-66/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the proper fix for a missing closing brace in the function ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com. The ft_cpu_setup() function in mpc8641hpcn.c should have been removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE, but was missed. Only, the sbc8641d was nominally still using it. It all got ripped out, and the funcality that was in ft_board_setup() was refactored to remove the CPU portions into the new file cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now.

But the 4xx NDFC already uses the SMC (Smart Media Card) ECC ordering, so this swapping in the HW ECC driver is bogus. This patch fixes this problem and now really uses the SMC ECC byte order.

This is not always true, and indeed on the ATNGW100, the refresh rate should really be 7.81 us. Add a refresh_period member to struct sdram_info and initialize it properly for both ATSTK1000 and ATNGW100. Out-of-tree boards will panic() until the refresh_period member is updated properly.
