New Revision: 5626
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5626

Log:
Same conversion as with resources from static arrays to lists, except
there is no free list.

Converting resource arrays to lists reduced the size of each device
struct from 1092 to 228 bytes.

Converting link arrays to lists reduced the size of each device struct
from 228 to 68 bytes.
