Again it needs to spend a little more time on the list to give others a fair chance at review.

Also I see it involves I2c so even though the change seems simple enough it should go through u-boot-i2c or I should atleast wait for some time for an ACK from Heiko.

I've applied such patches(e.g NAND, I2c and net related stuff)  but only after the respective custodians are OK with it
