Subject: video: Correct setting of cursor position
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9e95e909f6a6f9d17555d0ae1967fb3c6375b110;p=u-boot.git

video: Correct setting of cursor position

The ANSI codes are not correctly handled at present, in that the
requested X position is added to the current one.

Correct this and also call vidconsole_entry_start() to start a new text
line.
