a3774c1c3c spl: add serial download protocol (SDP) support
Add USB serial download protocol support to SPL. If the SoC started
in recovery mode the SPL will immediately switch to SDP and wait for
further downloads/commands from the host side.

b5c4d81b35 spl: fix Makefile for NOR, XIP and YMODEM
During the the conversion to $(SPL_TPL_), the SPL_ fragment was
left over for the NOR, XIP and YMODEM boot methods in SPL, making
these unselectable.

This commit fixes this by dropping the spurious 'SPL_' fragment
from each line.

f94e643ef9 spl: consistently use $(SPL_TPL_) to select features for SPL and TPL builds
To allow for a finer-grained control of features for TPL and SPL
builds all modules/boot-methods/etc. need to be consistently selected
based on the $(SPL_TPL_) macros.

This allows splitting the associated config-options in Kconfig: we
don't split the Kconfig options here and now, as this should happen on
an as-needed basis, whenever someone needs a feature/boot-method/etc.
in their TPL.

225d30b708 spl: add a 'return to bootrom' boot method
Some devices (e.g. the RK3368) have only limited SRAM, but provide
support for loading the next boot stage after our SPL performs basic
setup (e.g. DRAM).

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).

bcc1726a7b spl: add support to booting with ATF
ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation
about ATF at: https://github.com/ARM-software/arm-trusted-firmware

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.

ade8a1a6d3 drivers/mmc: move spl_mmc.c to common/spl
The mpc85xx repuires a special layout on the memory device that is
connected to the eSDHC controller interface. But the file spl_mmc.c
didn't handle this specfic case, there needs a special treatmen, in
the powerpc drictory. So, there is no longer to keep spl_mmc.c on
mpc85xx, CONFIG_SPL_FRAMEWORK is not set.

When CONFIG_SPL_MMC_SUPPORT is set and CONFIG_SPL_FRAMEWORK is not
set, there was an error in drivers/mmc/spl_mmc.c:

drivers/mmc/libmmc.o:(.got2+0x8): undefined reference to `spl_image'.

Now, the solution is to move the file "spl_mmc.c" to directory "common/spl".

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.

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.

47f7bcae8c SPL: Move the omap SPL framework to common/spl
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.
