Subject: common/lcd: Add command for writing to lcd-display
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1b7caf1123facf67816b03675952a5c700d0db9e;p=u-boot.git

common/lcd: Add command for writing to lcd-display

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.

So we cannot use the normal "echo ....", instead we write explicitly using
"lcdputs ..." for writing to the actual cursor position on LCD.
