* arm: spl: Allow board_init_r() to run with a larger stackSimon Glass2015-03-041-0/+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.

* arm: spl: Provide for a board-specific loaderSimon Glass2015-02-161-0/+5
| | | | | | | | | | | 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 Roese2015-01-281-1/+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: Change debug to printf for "Unsupported boot-device"Stefan Roese2014-11-231-1/+3
|/ | | | | | | | | | | | | | 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.

* SPL: Port SPL framework to powerpcStefan Roese2012-12-051-0/+16
| | | | | | | | | | | | | This patch enables the SPL framework to be used on powerpc platforms and not only ARM. timer_init() does not exist on PPC systems. The timer (decrementer) is initialized and enabled in interrupt_init() here. And currently interrupt_init() is called after relocation to SDRAM. Since the only powerpc SPL implementation (a3m071) doesn't need a timer, let's remove this timer_init() call for PPC systems. Signed-off-by: Stefan Roese <sr@denx.de>

This is required by tegra because the SPL runs on a different CPU from the image it is loading, so tegra specific initialization is required to start the host CPU.

* OMAP: networking support for SPLIlya Yanok2012-10-011-0/+9
| | | | | | | | | | | | | | This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

* SPL: Rework how we inform about un-headered imagesTom Rini2012-09-271-5/+2
| | | | | | | | | | | | First, remove the puts from the case where we don't have an mkimage header as this is somewhat common and intentional for no-arg target images. Second, rework the final switch statement in board_init_r to, in the case of !CONFIG_SPL_OS_BOOT be only about doing debug prints about if we know what the magic is or not (the CONFIG_SPL_OS_BOOT case is unchanged). Then we call jump_to_image_no_args(). This gives us the same behavior as before but with slightly smaller code. Signed-off-by: Tom Rini <trini@ti.com>

* SPL: Add option to skip copying of the mkimage headerStefan Roese2012-09-271-4/+17
| | | | | | | | | | | | | | | On some system (e.g. powerpc), the load-address and entry-point is located at address 0. So the current approach to load the image (payload) including the header to the address "load-address - 64" can't work here. This patch adds an flag to skip this copying including header to the SPL framework. By setting SPL_COPY_PAYLOAD_ONLY, only the playload will be copied. This will be used by the SPL NOR flash driver on powerpc. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | 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 Rini2012-09-271-0/+224
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. Signed-off-by: Tom Rini <trini@ti.com>
