2016-09-18spl: Print from which mmc slot spl is trying to bootHans de Goede
On some sunxi boards (and presumably also non sunxi boards) u-boot can be either loaded from a sdcard in a micro-sd slot, or from eMMC. Print which MMC spl tries to boot from, to help debugging. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-01-13arm: move gd handling outside of C codeAlbert ARIBAUD
As of gcc 5.2.1 for Thumb-1, it is not possible any more to assign gd from C code, as gd is mapped to r9, and r9 may now be saved in the prolog sequence, and restored in the epilog sequence, of any C functions. Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().

2015-11-18spl: change return values of spl_*_load_image()Nikita Kiryanov
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.

2015-10-20malloc_simple: Add support for switching to DRAM heapHans de Goede
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.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.

2015-03-04arm: spl: Allow board_init_r() to run with a larger stackSimon Glass
At present SPL uses a single stack, either CONFIG_SPL_STACK or CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and environment) require a lot of stack, some boards set CONFIG_SPL_STACK to point into SDRAM. They then set up SDRAM very early, before board_init_f(), so that the larger stack can be used. This is an abuse of lowlevel_init(). That function should only be used for essential start-up code which cannot be delayed. An example of a valid use is when only part of the SPL code is visible/executable, and the SoC must be set up so that board_init_f() can be reached. It should not be used for SDRAM init, console init, etc. Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new address before board_init_r() is called in SPL. The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

Microblaze currently doesn't use printf in SPL. So this one line was the only reference to it and resulted in the printf functionality to be pulled in. Exceeding the 4k size limit.
