The yeeloong and fuloong are based on Loongson-2 cpu platforms, They have
been discontinued. In future, The new products will switch to full
64-bit softwares
(from firmware to operating system).

The exist mips port is mips o32 ABI and for non UEFI platforms in
GRUB, This port is
for MIPS n64 ABI and UEFI platform. I think using a new cpu type
mips64 is better.
The code is clear for maintenance. ;)
