I fixed several typos in the Kconfig help, so ended up rewording it a
little. Your patches are good but please can you take a little more
time to read them before sending? Also please use "U-Boot"
consistently instead of u-boot, U-BOOT, etc. I am not claiming to be
perfect here either - in fact I am quite bad with typos sometimes. But
a read through will often reduce their number.

Fixed, and:

Applied to u-boot-rockchip, thanks!
