Subject: [PATCH] ARM: Add Winbond/Nuvoton NUC93X Platform support
Dear Russell,
The previous nuc932 support patches have been discarded by me and
because it belongs to
another SoCs series named nuc93x,at present, which included nuc931 and
nuc932, I think it is
better to create a new mach-nuc93x,So I made the patch,and request your
advice.Thanks!
