+ Read or write the extended CSD register of a MMC device.
+
+ Usage: extcsd dev [-r | -i index [-r | -v value -y]]
+
+ Options:
+ -i field index of the register
+ -r print the register as raw data
+ -v value which will be written
+ -y don't request when writing to one time programmable
fields
+ __CAUTION__: this could damage the device!
