2012-09-27SPL: Add NOR flash booting supportStefan Roese
SPL NOR flash booting support is quite simple. Only copying of the images is needed. On MPC5xxx we need to make sure to only use the standard memcpy() implementation and not the MPC5xxx specific one. As the MPC5xxx version has some complexity which is not needed for this SPL booting. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: NAND: Move arch/arm/cpu/armv7/omap-common/spl_nand.c to common/splTom Rini
We move the spl_nand_load_image function to common/spl. This will allow for easier integration of SPL-boots-Linux code on other arches. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: Use image_get_xxx() functions to access header valuesStefan Roese

2012-09-27SPL: do not use fix value for u-boot sizeStefano Babic
If an u-boot image is not found, SPL thinks to load a bare u-boot.bin image with a maximum size of 200KB. Use CONFIG_SYS_MONITOR_LEN instead. Signed-off-by: Stefan Roese <stefan.roese@gmail.com> Signed-off-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini
In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer, clear the BSS and call board_init_r. We mark this as weak as some platforms may need to perform additional initalization at this point. We provide a gd that we know will be in a usable location, once the BSS has been cleared to help with this as well. Finally, we no longer call relocate_code so remove that from the armv7 version. Next, both board_init_f and jump_to_image_linux are going to be inherently arch-specific, so move these versions to arch/arm/lib/spl.c Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: Move the omap SPL framework to common/splTom Rini
Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much. Signed-off-by: Tom Rini <trini@ti.com>
