Hi.
Current mips/mips/nexus.c code can't use most significant bit memory resource
device.
cfi0 at mem 0xffffffffbe000000-0xffffffffbfffffff on nexus0
nexus_alloc_resource: could not reserve resource for cfi0
device_attach: cfi0 attach returned 6

I check this problem then found my workaround at cfi_core.c. Thanks Adrian.
