b7a6e2c9c3 mmc: remove hc_wp_grp_size from struct mmc if not needed
hc_wp_grp_size is needed only if hardware partitionning is used.
On ARM removing it saves about 30 bytes of code space.

e6fa5a5461 mmc: compile out erase and write mmc commands if write operations are not enabled
Also remove erase_grp_size and write_bl_len from struct mmc as they are
not used anymore. On ARM, removing them saves about 100 bytes of code
space in SPL.

cf17789e07 mmc: make optional the support for eMMC hardware partitioning
Not all boards have an eMMC and not all users have a need for this.
Allow to compile it out. By default it is still included.

723b43daec blk: Remove various places that do flush cache after read
All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.

The underlying drivers should be responsible for the cache operation.
Remove these codes completely.

This patch allows to show the EXT_CSD[179] partition_config

  U-Boot> mmc partconf 0
  EXT_CSD[179], PARTITION_CONFIG:
  BOOT_ACK: 0x0

cd3d48807d mmc: add bkops-enable command
Add new command that provides possibility to enable the
background operations handshake functionality
(BKOPS_EN, EXT_CSD byte [163]) on eMMC devices.

This is an optional feature of eMMCs, the setting is write-once.
The command must be explicitly taken into use with
CONFIG_CMD_BKOPS_ENABLE.

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.
