BTW it looks like it is impossible to override machtype= parameter from
the kernel command line configured in boot/grub/grub.cfg, since linux
code in loongson/common/machtype.c uses the first occurence of
"machtype=" in arcs_cmdline[]. Is this behaviour by design or by
accident? Is this linux' fault or grub's fault? One could change grub
to append machtype= rather than prepend it to the command line...
cheers,
David
