Subject: hdt: Adding vesa mode support
X-Git-Tag: syslinux-3.84-pre5~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e9af8d807c3ab7b1a880bb307454481fd9a7150e;p=platform%2Fupstream%2Fsyslinux.git

hdt: Adding vesa mode support

Impact: cli can now be turned into vesa

Using the "vesa" keyword at boot time, you can enable the vesa mode for
the cli.
