CBFS used to work only on memory-mapped ROM (all x86). For
platforms like ARM, the ROM may come from USB, UART, or SPI -- any
serial devices and not available for memory mapping.
The idea is to allow (1) using CBFS on platforms without
memory-mapped ROM (ex, ARM), and (2) reading CBFS from multiple
source
at the same time (ex, receive updates from USB or UART cable).
I can understand other memory types (and there are some weird access
patterns, we had that on some gigabyte board already).
I'm not quite as sure about UART as CBFS source.
I'm quite opposed against "live" updates.
Any use case I can envision (for updates or UART loading) is better
implemented as payload specific function (and totally separate from
CBFS), but maybe I just lack creativity.
So, what's your use case?
