SPL: Rework how we inform about un-headered images 2012-09-27T18:20:28+00:00 Tom Rini trini@ti.com 2012-08-27T21:58:28+00:00 4212098181ac91e14374c1207b1e98595f1cc717 First, remove the puts from the case where we don't have an mkimage header as this is somewhat common and intentional for no-arg target images. Second, rework the final switch statement in board_init_r to, in the case of !CONFIG_SPL_OS_BOOT be only about doing debug prints about if we know what the magic is or not (the CONFIG_SPL_OS_BOOT case is unchanged). Then we call jump_to_image_no_args(). This gives us the same behavior as before but with slightly smaller code. Signed-off-by: Tom Rini <trini@ti.com>

SPL: Add option to skip copying of the mkimage header 2012-09-27T18:20:27+00:00 Stefan Roese sr@denx.de 2012-08-27T10:50:58+00:00 022b4975c8dd304fa9f949594784f78601ae07c2 On some system (e.g. powerpc), the load-address and entry-point is located at address 0. So the current approach to load the image (payload) including the header to the address "load-address - 64" can't work here. This patch adds an flag to skip this copying including header to the SPL framework. By setting SPL_COPY_PAYLOAD_ONLY, only the playload will be copied. This will be used by the SPL NOR flash driver on powerpc. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Tom Rini <trini@ti.com>

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>

SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linux 2012-09-27T16:49:59+00:00 Tom Rini trini@ti.com 2012-08-22T22:31:05+00:00 6507f133f3201ed5fb22e4a3d73c33b47497539d 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>
