set debug=foo,bar,baz

where "foo", "bar", "baz" are tags for which you want to enable debug
output or

set debug=all

to enable everything. You can also do

grub-install --debug-image=all

to set it from the earliest point in time possible.

You will need to check sources (look for grub_dprintf) to find out what
tags are in use.
