Some recent stuff was added to the io/flash layer to support accesses to 
the RedBoot FIS entries using e.g. /dev/flash1, although I now notice it 
really needs extending for multiple entries. If you want something really 
simple that might do. Look at the configuration options for that package.

That doesn't support tagging of ascii/binary though, but you could make a 
local modification to yourself to include that in FIS fields i.e. 
redboot/current/include/fis.h along with extra magic in flashiodev_init.
