* ppc4xx: acadia: Add fdt support and fix section overlap problemStefan Roese2008-05-08-1/+1
| | | | | | | | | | | | | This patch adds fdt (flattened device tree) support to the AMCC Acadia eval board. This increases the image size and it doesn't fit anymore into 256kByte. Since we didn't want to remove features from the configuration, we decided to increase the U-Boot image size (add one flash sector). Also changed the default environment definition to make it independent of such changes. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Canyonlands: Init SATA/PCIe port correctlyStefan Roese2008-04-02-12/+34
| | | | | | | | | Canyonlands (460EX) shares the first PCIe interface with the SoC SATA interface. This usage can be configured with the jumper J6. This patch correctly configures the SATA/PCIe PHY for SATA usage when this jumper is installed. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Canyonlands: Print SATA/PCIe configuration and board revisionStefan Roese2008-03-28-3/+39
| | | | | | | | | Canyonlands (460EX) shares the first PCIe interface with the SoC SATA interface. This usage can be configured with the jumper J6. This patch displays the current configuration upon bootup and changes the PCIe init loop, to only initialize the availabel PCIe slots. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Correctly pass phyiscal FLASH base address into dtbStefan Roese2008-03-27-1/+1
| | | | | | | | | The routine ft_board_setup() configures the EBC NOR mappings for the Linux physmap_of driver. Since on 460EX/GT we remap the FLASH from 0x4.fc00.0000 to 0x4.cc00.0000 because of the max. 16MByte boot-CS problem, we need to pass the corrected address here too.

* ppc4xx: Add AMCC Glacier 406GT eval board supportStefan Roese2008-03-27-9/+16
| | | | | | | | | | | | | | This patch adds support for the AMCC Glacier 460GT eval board. The main difference to the Canyonlands board are listed here: - 4 ethernet ports instead of 2 - no SATA port - no USB port Currently EMAC2+3 are not working. This will be fixed in a later release.

* ppc4xx: Add USB OHCI support to AMCC Canyonlands 460EX eval boardStefan Roese2008-03-15-0/+17

* ppc4xx: Add Canyonlands NAND booting supportStefan Roese2008-03-15-17/+179
| | | | | | | | | | | | | | | 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>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-19/+19
| | | | | | | | | | | | | | | | | | | 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: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setupStefan Roese2008-01-05-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On Katmai the complete auto-calibration somehow doesn't seem to produce the best results, meaning optimal values for RQFD/RFFD. This was discovered by GDA using a high bandwidth scope, analyzing the DDR2 signals. GDA provided a fixed value for RQFD, so now on Katmai "only" RFFD is auto-calibrated.

* ppc4xx: Enable hardware-fix for PCI/DMA errata on AMCC 440SP/SPe boardsStefan Roese2007-12-06-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the hardware-fix for the PCI/DMA errata's 19+22 by setting the FIXD bit in the SDR0_MFR register. Here a description of the symptoms: Problem Description ------------------------------ If a DMA is performed between memory and PCI with the DMA 1 Controller using prefetch, and as a result uses a special purpose buffer selected by the PCIXn Bridge Options 1 Register (PCIXn_BRDGOPT1[RBP7] - bits 31-29), the first part of the transfer sequence is performed twice. The PPC440SPe PCI Controller requests more data than was needed such that in the case of enforce memory protection, a host CPU exception can occur. No data is corrupted, because data transfer is stopped in the PCI Controller. Prefetch enable is specified by setting DMA Configuration Register (I2O0_DMAx_CFG[DXEPD] - bit 31) to 0. Behavior that may be observed in a running system --------------------------------------------------------------------------- 1. DMA performance is decreased because of the double access on the PCI bus interface. 2. If an illegal access to some address on the PCI bus is detected at the system level, a machine check or similar system error may occur. Workarounds Available ---------------------------------- 1. Do not program prefetch. Note that a prefetch command cannot be programmed without selecting a special purpose buffer. 2. To avoid crossing a physical boundary of the PCI slave device, add 512 bytes of address to the PCI address range. This patch was originally provided by Pravin M.

* 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 CONFIG_4xx_DCACHE compile options to enable cached SDRAMStefan Roese2007-10-31-0/+4
| | | | | | | | | | | | | | This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files and to the Sequoia TLB init code. Now the cache can be enabled on 44x boards by defining CONFIG_4xx_DCACHE in the board config file. This option will disappear, when more boards use is successfully and no more known problems exist. This is tested successfully on Sequoia and Katmai. The only problem that needs to be fixed is, that USB is not working on Sequoia right now, since it will need some cache handling code too, similar to the 4xx EMAC driver.

* 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: Fixed offset of refresh rate type for Bamboo on-board DDR SDRAMEugene O'Brien2007-10-31-2/+2
| | | | | | | | | | | | | This patch also adds a note to the fixed DDR setup for Bamboo NAND booting: Note: As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM modules are still plugged in. So it is recommended to remove the DIMM modules while using the NAND booting code with the fixed SDRAM setup!
