Here are mine numbers on QtMoko:
kernel size:
old: 1 833 952
new: 1 660 364
boot time
old: 1min 58s
new: 1min 30s
+ wihout debug stuff there is also some more RAM and it seems it will be
possible to compile moredrivers config < 2MB and subjectively everything is
faster. So for me this optimazations are definitely useful.
Maybe we could remove all the stuff from gta configs and put them in another
small file (gta02_debug_config?) so that if anybody wants to compile with debug
options he can just copy paste this file into moredrives/packaging config and he
will easily end up with the same debug options as we have now in configs.
