Current code allows up to 3 MBR partitions without extended one.
If more than 3 partitions are required, then extended partition(s)
must be used.
This commit allows up to 4 primary MBR partitions without the
need for extended partition.
Add mbr test unit. In order to run the test manually, mmc6.img file
of size 12 MiB or greater is required in the same directory as u-boot.
Test also runs automatically via ./test/py/test.py tool.
Running mbr test is only supported in sandbox mode.

These two functions are basically identical, just call the blk_*()
functions from disk_blk_*() functions. The only difference is that
the disk_blk_*() functions have to use parent block device as the
udevice implementing block device operations.
Add documentation on what those functions really do. The documentation
is not wrong even though it likely does look that way. The write/erase
functions really do not take into account the partition offset. This
will be fixed in the next patch.

The disk_blk_read() can be simplified using blk_read(), the only
things which needs to be handled are the read offset based on the
partition properties, and the block device ops which are coming
from the parent udevice, not the partition udevice.
The later is currently not implemented correctly as far as I can
tell, since the current code extracts block device descriptor from
the parent udevice which is OK, but extracts block device operations
from the partition udevice, which does not seem OK.
Switching to the blk_read() fixes that too.
The dev_get_blk() usage is simplified using UCLASS_PARTITION check.
Add non-confusing documentation what this really does.
Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
if (device_get_uclass_id(dev) == UCLASS_PARTITION) is always
true, because this disk_blk_read() function calls dev_get_blk()
above and checks its return value for non-NULL. The dev_get_blk()
performs the same device_get_uclass_id(dev) check and returns NULL
if not UCLASS_PARTITION. Drop the duplicate check.

Since commit 56670d6fb8 ("disk: part: use common api to lookup part
driver") part_get_info_by_name_type() ignores the part_type parameter
used to restrict the partition table type.
omap_mmc_get_part_size() and part_get_info_by_name() are the only
consumers.
omap_mmc_get_part_size() calls with part_type = PART_TYPE_EFI because at
the time of implementation a speed up could be gained by passing the
partition table type. After 5 years experience without this restriction
it looks safe to keep it that way.
part_get_info_by_name() uses PART_TYPE_ALL.
Move the logic of part_get_info_by_name_type() to part_get_info_by_name()
and replace the function in omap_mmc_get_part_size().

Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.
With that we support two primary use-cases:
- Being able to "distro boot" from a RAM disk. I.e., from an image
where the kernel is stored in /boot of some filesystem supported
by U-Boot.
- Accessing filesystems not located on exact partition boundaries,
e.g. when a filesystem image is wrapped in an FIT image and stored
in a disk partition.

This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.
It is only for SPL that we have two cases:
- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
use blk_legacy.c
Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.
