board_init should fill out entries in
struct global_data.
See other board like lopgicpd/zoom1 as an example.
Make sure to include the machine id.

This should be conditional included if the video in included

The video patch has logic to fall back reading
if (penv == NULL) {
penv = getenv("videomode");
if ((i == 1) || (penv == NULL))
Should similar logic be added here ?

This should be added to the list of
