[En-Nut-Discussion] UROM file system and RAM vs Flash allocation on AT91SAM

Hi all,

>From the Atmel AT91SAM Internet Radio Application Note re uromfs: 
"Unlike the 8-bit AVR implementation, for which it had
been designed initially, the 32-bit ARM version is not yet able to directly
read the file contents
from flash memory. Thus, the complete file system of about 7 Kbytes needs to
be copied to RAM
during runtime initialization." 

Does this draw-back still exist or do newer UROM drivers support reading
from Flash in-place?
