+Voltage ID and VDD override
+--------------------
+T4240 has a VID feature. U-boot reads the VID efuses and adjust the voltage
+accordingly. The voltage can also be override by command vdd_override. The
+syntax is
+
+vdd_override <voltage in mV>, eg. 1050 is for 1.050v.
+
+Upon success, the actual voltage will be read back. The value is checked
+for safety and any invalid value will not adjust the voltage.
+
+Another way to override VDD is to use environmental variable, in case of using
+command is too late for some debugging. The syntax is
+
+setenv t4240qds_vdd_mv <voltage in mV>
+saveenv
+reset
+
+The override voltage takes effect when booting.
+
+Note: voltage adjustment needs to be done step by step. Changing voltage too
+rapidly may cause current surge. The voltage stepping is done by software.
+Users can set the final voltage directly.

+
+
+Next, the ubifsmount command allows you to access filesystems on the

+
+=> help ubifsmount
+ubifsmount - mount UBIFS volume
+
+Usage:

+UBIFS: media format: w4/r0 (latest is w4/r0)

+
+Note that unlike Linux, U-Boot can only have one active UBI partition
+at a time, which can be referred to as ubi0, and must be supplied along

+
+
+And the ubifsload command allows you to load a file from a UBI
+filesystem:
+
+
+=> help ubifsload
+ubifsload - load file from an UBIFS filesystem
+
+Usage:
+ubifsload <addr> <filename> [bytes]

+
+
+Finally, you can unmount the UBI filesystem with the ubifsumount
+command:
+

+ubifsumount - unmount UBIFS volume
+
+Usage:
+ubifsumount - unmount current volume

+
+- interrupts: The interrupt number to the cpu.
+
+Required Board Specific Properties:
+
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+- samsung,bus-width: The width of the bus used to interface the devices
+ supported by DWC_mobile_storage (SD-MMC/EMMC/SDIO).
+ . Typically the bus width is 4 or 8.
+- samsung,timing: The timing values to be written into the
