Subject: common/lcd: Add command for setting cursor within lcd-console
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=d38d0c6a33c0ef087e030ca1731e485e854c05fa;p=u-boot.git

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.
