Re: [U-Boot] [PATCH 2/2] board/b4qds: VID support

The fuse status register provides the values from on-chip voltage ID efuses programmed at the factory. These values define the voltage requirements for the chip. u-boot reads FUSESR and translates the values into the appropriate commands to set the voltage output value of an external voltage regulator.

B4860QDS has a PowerOne ZM7300 programmable digital Power Manager which is programmed as per the value read from the fuses.

Reference for this code is taken from t4qds VID implementation.
