Currently the
cablesel |= (sb->ide0_80pin_cable << 28) |
(sb->ide0_80pin_cable << 20) |
(sb->ide1_80pin_cable << 12) |
(sb->ide1_80pin_cable << 4);
in vt8237r_ide.c ends up doing
cablesel |= 0xfffffff0;
(with both bits set to 1) which is probably not the intended result. ;)
After a short discussion on irc the consensus was to change the
bitfields to u8 as it's probably not worth it using bitfields here.
