aea3d40d05 spl: Add a debug string before the jump to U-Boot
As a debug option, add positive confirmation that SPL has completed
execution. This can help with diagnosing the location of unexpected hangs.

070d00b8dc dm: spl: Allow device tree/driver model in board_init_f()
Add an spl_init() function that does basic init such that board_init_f() can
use simple malloc(), device tree and driver model. Each one is set up only
if enabled for SPL.

Note: We really should refactor SPL such that there is a single
board_init_f() and rename the existing weak board_init_f() functions
provided by boards, calling them from the single board_init_f().

db910353a1 arm: spl: Allow board_init_r() to run with a larger stack
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.

e860d012c4 spl: Change printf to puts for "Unsupported boot-device"
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.

18f26fdbd0 spl: Change debug to printf for "Unsupported boot-device"
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.

This patch enables the SPL framework to be used on powerpc platforms

timer_init() does not exist on PPC systems. The timer (decrementer) is

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.

7ac2fe2da2 OMAP: networking support for SPL
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.

4212098181 SPL: Rework how we inform about un-headered images
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.

6507f133f3 SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linux
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

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
