* arm: spl: Provide for a board-specific loaderSimon Glass2015-02-16-0/+4
| | | | | | | | | | | Some boards have a special way of loading U-Boot that does not fit with the existing SPL code. For example sunxi uses an 'FEL' mode where U-Boot is loaded over USB. Add a CONFIG option and boot mode for this.

* arm: socfpga: Zap spl.h and ad-hoc related symsMarek Vasut2014-10-27-1/+1
| | | | | | | | | | | | | Switch to the common spl.h file and zap the arch/spl.h . Since the arch/spl.h contained various ad-hoc symbols, zap those symbols as well and rework the board configuration a little so it doesn't depend on them.

* spl: consolidate arch/arm/include/asm/arch-*/spl.hMasahiro Yamada2014-06-06-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch/arm/include/asm/spl.h requires all SoCs to have arch/arm/include/asm/arch-*/spl.h. But many of them just define BOOT_DEVICE_* macros. Those macros are used in the "switch (boot_device) { ... }" statement in common/spl/spl.c. So they should not be archtecture specific, but be described as a simpile enumeration. This commit merges most of arch/arm/include/asm/arch-*/spl.h into arch/arm/include/asm/spl.h. With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h will be merged, while I am not sure about OMAP and Exynos.

* Replace __bss_end__ with __bss_endSimon Glass2013-03-15-1/+1
| | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini2012-09-27-0/+5
| | | | | | | | | | | | | | 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>
* SPL: Move the omap SPL framework to common/splTom Rini2012-09-27-40/+0
| | | | | | | | | | | | | 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.
