malloc_simple uses a part of the stack as heap, initially it uses SYS_MALLOC_F_LEN bytes which typically is quite small as the initial stacks sits in SRAM and we do not have that much SRAM to work with. When DRAM becomes available we may switch the stack from SRAM to DRAM to give use more room. This commit adds support for also switching to a new bigger malloc_simple heap located in the new stack. Note that this requires spl_init to be called before spl_relocate_stack_gd which in practice means that spl_init must be called from board_init_f.

spl_relocate_stack_gd only gets called from arch/arm/lib/crt0.S which clears the bss directly after calling it, so there is no need to clear it from spl_relocate_stack_gd. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Simon Glass <sjg@chromium.org>
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

As we discussed a couple of times, negative CONFIG options make our life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ... and here is another one. Now, there are three boards enabling OF_CONTROL on SPL: - socfpga_arria5_defconfig - socfpga_cyclone5_defconfig - socfpga_socrates_defconfig This commit adds CONFIG_SPL_OF_CONTROL for them and deletes CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert the logic.

This patch introduces the option to boot from a MMC card parition with an offset. This can be done by using both defines together: define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION 1 define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR ((160 << 10) / 512) The example above loads the main U-Boot at offset 160KiB from the MMC partition 1.

As a debug option, add positive confirmation that SPL has completed execution. This can help with diagnosing the location of unexpected hangs. Signed-off-by: Simon Glass <sjg@chromium.org>
Add an spl_init() function that does basic init such that board_init_f() can use simple malloc(), device tree and driver model. Each one is set up only if enabled for SPL. Note: We really should refactor SPL such that there is a single board_init_f() and rename the existing weak board_init_f() functions provided by boards, calling them from the single board_init_f().
