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> |
