* spl: Move spl_board_load_image() into a generic headerSimon Glass2016-10-06-9/+0
| | | | | | | | | At present this is only used on ARM and sandbox, but it is just as applicable to other architectures. Move the function prototype into the generic SPL header. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

* spl: change return values of spl_*_load_image()Nikita Kiryanov2015-11-18-2/+8
| | | | | | | | | | | | | | | | | | | | | | | Make spl_*_load_image() functions return a value instead of hanging if a problem is encountered. This enables main spl code to make the decision whether to hang or not, thus preparing it to support alternative boot devices. Some boot devices (namely nand and spi) do not hang on error. Instead, they return normally and SPL proceeds to boot the contents of the load address. This is considered a bug and is rectified by hanging on error for these devices as well.

* arm: spl: Avoid setting up a duplicate global data structureSimon Glass2015-03-04-0/+2
| | | | | | | | | | | | This is already set up in crt0.S. We don't need a new structure and don't really want one in the 'data' section of the image, since it will be empty and crt0.S's changes will be ignored. As an interim measure, remove it only if CONFIG_DM is not defined. This allows us to press ahead with driver model in SPL and allow the stragglers to catch up.

* 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.
