I didn't find any functions used for which the documentation specifies to

The only Linux specific header <linux/fs.h> is needed for BLKGETSIZE,
document that.

This macro saves a few lines of code but is harder to read than the
equivalent code spelled out. IMHO the latter is more important, so
expand the macro everywhere and drop it.

While touching this also unbreak the strings used there for better
grepability.

Adding 'continue' option to:
gp create

write_reliability set

Partitioning commands are connected, register PARTITION_SETTING_COMPLETED
should not be written until all settings have been done.
The continue option enables writing more than one partitioning setting before
sealing settings.

Add commands to get and set write protect modes for the specified
areas of the user partition. The ability to set permanent write
protect is #ifdef'd with "DANGEROUS_COMMANDS_ENABLED" because
it has the ability to make the eMMC device and possibly the system
permanently unusable.

Adding support for field firmware update over multiple command ioctl.
As multiple command ioctl is supported only from kernel 4.4, this patch
should be used against kernel 4.4 and above.

Known issues:
- There is no support for Multiple Block write commands (CMD25) in existing
  IOCTL implementation
- In case MODE_OPERATION_CODES field is not supported by the device
  manual reset of the device/platform is required.
  The reset issue discussed in another email thread - " [RFC 0/6] mmc:
  Field Firmware Update"

mmc rpmb write-key <rpmb device> <key file>
  Program authentication key which is 32 bytes length and stored in the specified file.
  Also you can specify '-' instead of key file path and utility will read the key from stdin.
  BEWARE: key can be programmed only once!
  Example:
    $ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | mmc rpmb write-key /dev/mmcblk0rpmb -

mmc rpmb read-counter <rpmb device>
  Counter value for the <rpmb device> will be read to stdout.

mmc rpmb read-block <rpmb device> <address> <blocks count> <output file> [key file]
  Blocks of 256 bytes will be read from <rpmb device> to output file or stdout if '-'
  is specified instead of regular path. If key is specified - read data will be verified.
  Instead of regular path you can specify '-' and key will be read from stdin.
  Example:
    $ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | \
        mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block -
  or read the block without verification
    $ mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block

mmc rpmb write-block <rpmb device> <address> <256 byte data file> <key file>
  Block of 256 bytes will be written from data file to <rpmb device>.
  Also you can specify '-' instead of key file path or data file and utility will read the
  data from stdin.
  Example:
    $ (awk 'BEGIN {while (c++<256) printf "a"}' | echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH) | \
      mmc rpmb write-block /dev/mmcblk0rpmb 0x02 - -

bit; once this bit is set there are many other parameters in
EXT_CSD which can no longer be set.
