- Convert the non-relocation part of board_init_f to spl_board_init, turn on CONFIG_SPL_BOARD_INIT in the configs.
- Remove duplicated code.
- Add spl_boot_device() that returns the statically chosen boot device.

We move the spl_nand_load_image function to common/spl.  This will allow
for easier integration of SPL-boots-Linux code on other arches.

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
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.

This is an OMAP/related-specific function, move calling it to
spl_board_init() and turn on CONFIG_SPL_BOARD_INIT on the boards that
enabled NAND and didn't enable this already.

- Remove includes we don't need
- Switch some printf statements to puts
- Convert some printf statements to debug, introduce new puts statements
  - In most cases saying just "No mkimage signature, assuming
    u-boot.bin" or similar is sufficient.  This also means the non-DEBUG
    case doesn't need printf, in the core of SPL.
  - The other case here is that PLAIN_VERSION provided what we wanted
    already, so just use it.

Move the default omap/related-centric board_mmc_init to
arch/arm/cpu/armv7/omap-common/boot-common.c and move the type defines
to <asm/spl.h>.  Also use mmc->read_bl_len rather than MMCSD_SECTOR_SIZE
