That's 123KiB which is definitely enough. For now we need to put 15KiB data there, but if we include NPE-C microcode at a later date there should still be room :)

Anyone got a preference for where we put the microcode in flash?

I propose that it go in the last block of flash, after the FIS
directory, but before the Sercomm trailer.

Slugimage denotes this as the "Payload" area (see
http://www.nslu2-linux.org/wiki/Info/LastBlockMemoryMap for details).

I propose the start of the currently defined Payload area be used for
NPE microcode.

What is the maximum size that we need? The unused payload area is
currently 0x1eff0 byte long.

should both add the functionality to APEX *and* put the firmware into
flash so that the kernel can load it as well.
