Subject: [PATCH] common/lcd: Add command for setting cursor within lcd-console
Sometimes we do not want redirect u-boot's console to screen but anyway we want
write out some status information out of a u-boot script to the display.
To define the specific position of the string to be written, we have to set
the cursor with "setcurs" before writing.
