* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-259/+526
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 1 of 2): * Rolls up a suite of changes to enable correct primordial stack and global data handling when the data cache is used for such a purpose for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS). * Related to the first, unifies DDR2 SDRAM and ECC initialization by eliminating redundant ECC initialization implementations and moving redundant SDRAM initialization out of board code into shared 4xx code. * Enables MCSR visibility on the 405EX(r). * Enables the use of the data cache for initial RAM on both AMCC's Kilauea and Makalu and removes a redundant CFG_POST_MEMORY flag from each board's CONFIG_POST value. - Removed, per Stefan Roese's request, defunct memory.c file for Makalu and rolled sdram_init from it into makalu.c. With respect to the 4xx DDR initialization and ECC unification, there is certainly more work that can and should be done (file renaming, etc.). However, that can be handled at a later date on a second or third pass. As it stands, this patch moves things forward in an incremental yet positive way for those platforms that utilize this code and the features associated with it.

* PPC4xx: Simplified post_word_{load, store}Grant Erickson2008-06-03-15/+11

* Big white-space cleanup.Wolfgang Denk2008-05-21-36/+36
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

| * ppc4xx: Pass PCIe root-complex/endpoint configuration to Linux via the fdtStefan Roese2008-04-25-0/+42
| | | | | | | | | | | | | | | | | | | | The PCIe root-complex/endpoint setup as configured via the "pcie_mode" environment variable will now get passed to the Linux kernel by setting the device_type property of the PCIe device tree node. For normal root- complex configuration it will keep its defaults value of "pci" and for endpoint configuration it will get changed to "pci-endpoint". Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Add dcache_enable() for 440Stefan Roese2008-04-22-0/+2
| | | | | | | | | | | | dcache_enable() was missing for 440 and the patch 017e9b7925f74878d0e9475388cca9bda5ef9482 ["allow ports to override bootelf "] behavior uses this function. Note: Currently the cache handling functions like d/icache_disable/enable() are NOP's on 440. This may be changed in the future. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Fix crash on sequoia with cache enabledAnatolij Gustschin2008-04-18-1/+3
| | | | | | | | | | | Currently U-Boot crashes on sequoia board in CPU POST if cache is enabled (CONFIG_4xx_DCACHE defined). The cache won't be disabled by change_tlb before CPU POST because there is an insufficient adress range check since CFG_MEM_TOP_HIDE was introduced. This patch tries to fix this problem.

* ppc4xx: Reconfigure PLL for 667MHz processor for PPC440EPxMike Nuss2008-03-27-1/+99
| | | | | | | | | | | | On PPC440EPx without a bootstrap I2C EEPROM, the PLL can be reconfigured after startup to change the speed of the clocks. This patch adds the option CFG_PLL_RECONFIG. If this option is set to 667, the CPU initialization code will reconfigure the PLL to run the system with a CPU frequency of 667MHz and PLB frequency of 166MHz, without the need for an external EEPROM.

* 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 (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>

| | | | | | | | | | | | | | | | | | | | | | The current ndfc HW ECC implementation swaps the first two ECC bytes. 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.

| | | | | | | | | | | | | | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | | | | | | | | | | | | | The privious 4xx POST implementation only supported storing the POST WORD in OCM. Since we need to reserve the OCM on LWMON5 for the logbuffer we need to store the POST WORD in some other non volatile location.
