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.

2015-02-16arm: spl: Provide for a board-specific loaderSimon Glass
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.

2015-01-28spl: Change printf to puts for "Unsupported boot-device"Stefan Roese
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. Lets change the printf back to puts so that Microblaze is fixed again. The only drawback is that the detected boot-device number will not be printed. But this message alone should be helpful enough to get an idea where the boot process is broken.

2015-01-14spl: spl_nor: surround Linux-load code with #ifdef CONFIG_SPL_OS_BOOTMasahiro Yamada
If CONFIG_SPL_NOR_SUPPORT is defined, spl_nor_load_image() requires spl_start_uboot(), CONFIG_SYS_OS_BASE, CONFIG_SYS_SPL_ARGS_ADDR, CONFIG_SYS_FDT_BASE to be defined even if users just want to run U-Boot, not Linux. This is inconvenient. This patch is following the codying style of common/spl/spl_nand.c. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-11-23spl: Change debug to printf for "Unsupported boot-device"Stefan Roese
We had the problem on an AM33xx platform, that SPL detected an unsupported boot-device. But since this message is a debug message it took a bit of time to really know, where the hangup in SPL resulted from. So let's change this debug message to a printf and also print the detected boot-device that is not supported. This makes debugging of such cases much easier.
