Re: Blob boot from Compact Flash (ext2fs)

So, are you saying that the code for the Sharp boards got integrated
already?  If so, I'd really appreciate a snapshot from CVS.

A common mistake.  The uboot code is much much worse.

Good to know.  I rewrote the memory initialization code once already.
I'll do so again as soon as I can get something running on the
KEV7A400.
