c4d660d4d0 dm: mmc: Allow disabling driver model in SPL
At present if U-Boot proper uses driver model for MMC, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.

Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By
default these follow their non-SPL versions, but this can be changed by
boards which need it.

At present erase is not suported with CONFIG_DM_OPS. Add it so that MMC
devices can be erased.

d2d9bdfcf9 spl: saveenv: adding saveenv support in SPL
By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.

Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.

c0c76ebae3 mmc: Move tracing code into separate functions
Move this code into separate functions so that it can be used from the uclass
also. Add static inline versions for when the option is disabled.

c40704f4b1 mmc: Move MMC boot code into its own file
Rather than having an #ifdef in the main mmc.c file, control this feature
from the Makefile by moving the code into its own file.

correct function signature to avoid a build warnings in SPL. Fix this.

Add support for enabling CONFIG_BLK with MMC. This involves changing a
few functions to use struct udevice and adding a MMC block device driver.

c40fdca6b7 dm: mmc: Move the device list into a separate file
At present the MMC subsystem maintains its own list of MMC devices. This
cannot work with driver model, which needs to maintain this itself. Move the
list code into a separate 'legacy' file. The core MMC code remains, and will
be shared with the driver-model implementation.

4101f68792 dm: Drop the block_dev_desc_t typedef
Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long
and causes 80-column violations, rename it to struct blk_desc.

7c4213f6a5 block: pass block dev not num to read/write/erase()
This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

da61fa5f42 mmc: don't support write & erase for SPL builds
For SPL builds this is just dead code since we'll only need to read.
Eliminating it results in a significant size reduction for the SPL
binary, which may be critical for certain platforms where the binary
size is highly constrained.
