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.

- 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.

When storage devices contain files larger than the embedded RAM, it is
useful to be able to read these files by chunks, e.g. for a software
update to the embedded NAND Flash from an external storage device (USB
stick, SD card, etc.).

Hence, this patch makes it possible by adding a new FAT API to read
files from a given position. This patch also adds this feature to the
fatload command.

This implements the following:

part uuid mmc 0:1
  -> print partition UUID
part uuid mmc 0:1 uuid
  -> set environment variable to partition UUID
part list mmc 0
  -> list the partitions on the specified device

"part uuid" can be useful when writing a bootcmd which searches all
known devices for something bootable, and then wants the kernel to
use the same partition as the root device, e.g.:

part uuid ${devtype} ${devnum}:${rootpart} uuid
setenv bootargs root=PARTUUID=${uuid} ...

The MSDOS/MBR partition table includes a 32-bit unique ID, often referred
to as the NT disk signature. When combined with a partition number within
the table, this can form a unique ID similar in concept to EFI/GPT's
partition UUID.

This patch generates UUIDs in the format 0002dd75-01, which matches the
format expected by the Linux kernel.

Each EFI partition table entry contains a UUID. Extend U-Boot's struct
disk_partition to be able to store this information, and modify
get_partition_info_efi() to fill it in.

The implementation of uuid_string() was derived from the Linux kernel,
tag v3.6-rc4 file lib/vsprintf.c function uuid_string().

Enhance get_partition_info_efi() to range-check the partition number.
This prevents invalid partitions being accessed, and prevents access

Rework get_device_and_partition() to:
a) Implement a new partition ID of "auto", which requests that U-Boot
   search for the first "bootable" partition, and fall back to the first
   valid partition if none is found. This way, users don't need to
   specify an explicit partition in their commands.
b) Make use of get_device().
c) Add parameter to indicate whether returning a whole device is
   acceptable, or whether a partition is mandatory.
d) Make error-checking of the user's device-/partition-specification
   more complete. In particular, if strtoul() doesn't convert all
   characters, it's an error rather than just ignored.

The resultant device/partition returned by the function will be as
follows, based on whether the disk has a partition table (ptable) or not,
and whether the calling command allows the whole device to be returned
or not.

(D and P are integers, P >= 1)

D
D:
  No ptable:
    !allow_whole_dev: error
    allow_whole_dev: device D
  ptable:
    device D partition 1
D:0
  !allow_whole_dev: error
  allow_whole_dev: device D
D:P
  No ptable: error
  ptable: device D partition P
D:auto
  No ptable:
    !allow_whole_dev: error
    allow_whole_dev: device D
  ptable:
    first partition in device D with bootable flag set.
    If none, first valid paratition in device D.

Note: In order to review this patch, it's probably easiest to simply
look at the file contents post-application, rather than reading the
patch itself.

This patch introduces function get_device(). This looks up a
block_dev_desc_t from an interface name (e.g. mmc) and device number
(e.g. 0). This function is essentially the non-partition-specific
