* ppc4xx: Add Sequoia RAM-booting targetStefan Roese2009-06-12-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds another build target for the AMCC Sequoia PPC440EPx eval board. This RAM-booting version is targeted for boards without NOR FLASH (NAND booting) which need a possibility to initially program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000) configured to setup the SDRAM, this debugger can load this RAM- booting image to the target address in SDRAM (in this case 0x1000000) and start it there. Then U-Boot's standard NAND commands can be used to program the NAND FLASH (e.g. "nand write ..."). Here the commands to load and start this image from the BDI2000: 440EPX>reset halt 440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin 440EPX>go 0x1000000 Please note that this image automatically scans for an already initialized SDRAM TLB (detected by EPN=0). This TLB will not be cleared. This TLB doesn't need to be TLB #0, this RAM-booting version will detect it and preserve it. So booting via BDI2000 will work and booting with a complete different TLB init via U-Boot works as well. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Fixup chip-selects in dtb for NAND-booting SequoiaStefan Roese2009-04-16-2/+56
| | | | | | | | | | | | | | | | | | | | Currently the NOR & NAND support in Linux only works for the "standard" Sequoia, the version booting for NOR flash. The NAND-booting version has the chip-selects swapped. Here the chip-select mappings: "Standard" NOR-booting version: CS0 NOR CS3 NAND NAND-booting version: CS0 NAND CS3 NOR With this path the dtb gets fixed-up, so that the correct chip-select numbers are patched in the dtb enabling correct NOR & NAND support in Linux on the NAND-booting Sequoia version.

| | | | | | | | | | | | | | | | | | | | | | schematic. The Sequoia board has two UARTs in "4-pin" mode.

| * ppc4xx: Remove redundant ft_board_setup() functions from some 4xx boardsStefan Roese2008-07-13-21/+0
| | | | | | | | | | | | | | | | | | This patch removes some ft_board_setup() functions from some 4xx boards. This can be done since we now have a default weak implementation for this in cpu/ppc4xx/fdt.c. Only board in need for a different/custom implementation like canyonlands need their own version.

* | ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This 2nd patch now removes all UIC mask bit definition. They should be generated from the vectors by using the UIC_MASK() macro from now on. This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>

* [PATCH] Run new sequoia boards with an EBC speed of 83MHzJeffrey Mann2007-05-16-2/+8
| | | | | | | | | | | | | | | Because the Sequoia board does not boot with an EBC faster than 66MHz, the clock divider are changed after the initial boot process. This allows for maximum clocking speeds to be achieved on newer boards. Sequoia boards with 666.66 MHz processors require that the EBC divider be set to 3 in order to start the initial boot process at a slower EBC speed. After the initial boot process, the divider can be set back to 2, which will cause the boards to run at 83.333MHz. This is backward compatible with boards with 533.33 MHz processors, as these boards will already be set with an EBC divider of 2. Signed-off-by: Jeffrey Mann <mannj@embeddedplanet.com>
