Embedded device command line partition
Embedded device command line partition parsing
=====================================================================
Read block device partition table from command line.
The partition used for fixed block device (eMMC) embedded device.
It is no MBR, save storage space. Bootloader can be easily accessed
Support for reading the block device partition table from the command line.
It is typically used for fixed block (eMMC) embedded devices.
It has no MBR, so saves storage space. Bootloader can be easily accessed
by absolute address of data on the block device.
Users can easily change the partition.

When used with Renesas SDHI hardware, the following compatibility strings
configure various model-specific properties:
"renesas,sh7372-sdhi": (default) compatible with SH7372
"renesas,r8a7740-sdhi": compatible with R8A7740: certain MMC/SD commands have to
wait for the interface to become idle.

Reference clock source is determined by the value, which is holded
in CKSEL bits in TMR_CTRL register. "fsl,cksel" property keeps the
value, which will be directly written in those bits, that is why,
according to reference manual, the next clock sources can be used:

input is used for this purpose);
