spl: change return values of spl_*_load_image()

2015-11-18T19:50:02+00:00

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.

arm: spl: Avoid setting up a duplicate global data structure

2015-03-04T19:55:04+00:00

This is already set up in crt0.S. We don't need a new structure and don't
really want one in the 'data' section of the image, since it will be empty
and crt0.S's changes will be ignored.

As an interim measure, remove it only if CONFIG_DM is not defined. This
allows us to press ahead with driver model in SPL and allow the stragglers
to catch up.

arm: spl: Provide for a board-specific loader

2015-02-16T19:15:06+00:00

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.

arm: socfpga: Zap spl.h and ad-hoc related syms

2014-10-27T01:26:24+00:00

Switch to the common spl.h file and zap the arch/spl.h . Since the arch/spl.h
contained various ad-hoc symbols, zap those symbols as well and rework the
board configuration a little so it doesn't depend on them.

spl: consolidate arch/arm/include/asm/arch-*/spl.h

2014-06-06T08:05:34+00:00

arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.

But many of them just define BOOT_DEVICE_* macros.

Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.

So they should not be archtecture specific, but be described as
a simpile enumeration.

This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.

With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

Replace __bss_end with bss_end

2013-03-15T20:13:54+00:00

Note this is a tree-wide change affecting multiple architectures.

At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.

Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linux

2012-09-27T16:49:59+00:00

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
