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.

ea8256f072 SPL: Port SPL framework to powerpc
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.

a759f1e0db SPL: make jump_to_image_no_args a weak symbol
Change jump_to_image_no_args() to a weak symbol to allow override by
SoC specific code.  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.  Pass in spl_image
as a parameter for the same reason.

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.

022b4975c8 SPL: Add option to skip copying of the mkimage header
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.

33d346464a SPL: Add NOR flash booting support
SPL NOR flash booting support is quite simple. Only copying of the

On MPC5xxx we need to make sure to only use the standard memcpy()
implementation and not the MPC5xxx specific one. As the MPC5xxx
version has some complexity which is not needed for this SPL
booting.

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
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

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL

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.
