* | spl: mmc: use block device number, not hard-coded 0Eric Nelson2015-12-14-3/+5
|/ | | | | | | | | | | In order to support boot from multiple devices through board_boot_order, it's necessary to use the block number of a device. The use of a hard-coded 0 for the device number also creates a need to re-order block devices for use in SPL like this: http://git.denx.de/?p=u-boot.git;a=blob;f=board/freescale/mx6slevk/mx6slevk.c;hb=HEAD#l195 Signed-off-by: Eric Nelson <eric@nelint.com>
* spl: mmc: Unify non/driver model spl_mmc_find_device()Simon Glass2015-12-05-32/+9
| | | | | | | | | | | | | | | | | | | It is risky to have two different functions with much the same code. Future authors may update one but not the other. It is hard to see which parts are the same and which are different. Unify the functions and drop the differences that are not really needed. Note that one puts() becomes printf() as Tom mentioned that this does not affect image size: https://patchwork.ozlabs.org/patch/537276/ Note: It would be better to have an empty printf() and avoid the #ifdef for CONFIG_SPL_LIBCOMMON_SUPPORT.

| | | | | | | | | | | | | | | | | | | | | | | 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.

* spl: mmc: add break statements in spl_mmc_load_image()Nikita Kiryanov2015-11-18-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original intention of the mmc load_image() function was to try multiple boot modes before failing. This is evident by the lack of break statements in the switch, and the following line in the default case: puts("spl: mmc: no boot mode left to try\n"); This implementation is problematic because: - The availability of alternative boot modes is very arbitrary since it depends on the specific order of the switch cases. If your boot mode happens to be the first case, then you'll have a bunch of other boot modes as alternatives. If it happens to be the last case, then you have none. - Opting in/out is tied to config options, so the only way for you to prevent an alternative boot mode from being attempted is to give up on the feature completely. - This implementation makes the code more complicated and difficult to understand. Address these issues by inserting a break statements between the cases to make the function try only one boot mode.

* malloc_simple: Add support for switching to DRAM heapHans de Goede2015-10-20-0/+12
| | | | | | | | | | | | | | | | | 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.

* arm: spl: Allow board_init_r() to run with a larger stackSimon Glass2015-03-04-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | 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.

* spl: Change printf to puts for "Unsupported boot-device"Stefan Roese2015-01-28-1/+1
| | | | | | | | | | | | | | 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.

* spl: spl_nor: surround Linux-load code with #ifdef CONFIG_SPL_OS_BOOTMasahiro Yamada2015-01-14-25/+39
| | | | | | | | | | | 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>
