* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-107/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 2 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.

* Big white-space cleanup.Wolfgang Denk2008-05-21-23/+23
| | | | | | | | | | | 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: Update Kilauea CPLD configuration with USB PHY reset bitStefan Roese2008-01-14-7/+7
| | | | | | | | | Now that bit 29 is the USB PHY reset bit, update the Kilauea port to remove the USB PHY reset after powerup. The CPLD will keep the USB PHY in reset (active low) until the bit is set to 1 in board_early_init_f(). Signed-off-by: Stefan Roese <sr@denx.de>
* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-2/+2
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: Bring 4xx fdt support up-to-dateStefan Roese2007-12-13-0/+1
| | | | | | | | This patch update the 4xx fdt support. It enabled fdt booting on the AMCC Kilauea and Sequoia for now. More can follow later quite easily. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: 405EX: Correctly enable USB pinsStefan Roese2007-12-08-0/+7
| | | | | | | | This patch selects the USB data pins in the 405EX GPIO and MFC (multi function control) registers. This is done for the AMCC Kilauea and Makalu eval boards. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Kilauea: Add PCIe reset assertion upon power-upStefan Roese2007-11-30-9/+6
| | | | | | | | This manual PCIe reset triggering solves the problem seen with the Intel EPRO/1000 card, which was not detected (link not established) upon power-up reset. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Add AMCC Kilauea/Haleakala NAND booting supportStefan Roese2007-11-03-1/+148
| | | | | | | This patch adds NAND booting support for the AMCC 405EX(r) eval boards. Again, only one image supports both targets. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add initial AMCC Haleakala PPC405EXr eval board supportStefan Roese2007-10-31-3/+33
| | | | | | | | | | The Haleakala is nearly identical with the Kilauea eval board. The only difference is that the 405EXr only supports one EMAC and one PCIe interface. This patch adds support for the Haleakala board by using the identical image for Kilauea and Haleakala. The distinction is done by comparing the PVR. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Fix size setup in Kilauea DDR2 init routineStefan Roese2007-10-31-26/+26
| | | | | | | | | The size was initilized wrong. Instead of 256MB, the DDR2 controller was setup to 512MB. Now the correct values is used. This patch also does a little cleanup and adds a comment here. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Dynamic configuration of 4xx PCIe mode as root or endpoint modeStefan Roese2007-10-31-34/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for dynamic configuration of PCIe ports for the AMCC PPC4xx boards equipped with PCIe interfaces. These are the PPC440SPe boards Yucca & Katmai and the 405EX board Kilauea. This dynamic configuration is done via the "pcie_mode" environement variable. This variable can be set to "EP" or "RP" for endpoint or rootpoint mode. Multiple values can be joined via the ":" delimiter. Here an example: pcie_mode=RP:EP:EP This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2 as endpoint. Per default Yucca will be configured as: pcie_mode=RP:EP:EP Per default Katmai will be configured as: pcie_mode=RP:RP:REP Per default Kilauea will be configured as: pcie_mode=RP:RP Signed-off-by: Tirumala R Marri <tmarri@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable device tree support (fdt) on Kilauea per defaultStefan Roese2007-10-31-0/+14
| | | | | | | | | | | | | This patch enables the fdt support on the AMCC Kilauea eval board. Additionally now EBC ranges fdt fixup is included to support NOR FLASH mapping via the Linux physmap_of driver. This Kilauea port now support booting arch/ppc and arch/powerpc Linux kernels. The default environment "net_nfs" is for arch/ppc and "net_nfs_fdt" is for arch/powerpc. In the long run, arch/ppc support will be removed. Signed-off-by: Stefan Roese <sr@denx.de>
