Just saw this commited. It makes Cubieboard2 fully useable so far.
Kernel rebuild with fs on ahci:
(...)
ld -T ldscript --warn-common -nopie -S -o bsd ${SYSTEM_HEAD} vers.o ${OBJS}
text data bss dec hex
3744040 139412 479308 4362760 429208
25m50.10s real 17m18.26s user 1m28.06s system
Just as a comparison, it takes around 20 min on Wandboard with fs on nfs and
around 23 min on BeagleBone Black with fs also on nfs.
Thank you.
