Re: RedBoot: fis delete won't erase

fis delete no longer needs to erase the flash as fis free now uses the
FIS directory to determine free space. Erasing the flash twice (once
for fis delete and then again for fis create) is also unnecessary.
I'll look at this when I'm back in my office, but in reality, it
doesn't really matter to be extra thorough - the "erase" routines
are optimized to check for erased data and avoid touching the device
if the segment is already blank.
Hmm. I definately remember it erasing it twice. (investigates further)
It seems that checking for erased blocks is broken in my local tree.
Still, not doing an erase in fis delete would allow you to recover from
a botched fis delete command. Not that I do that very often... :P
