mtd-19990809 including readonly DiskOnChip driver.

[David Woodhouse]

I've updated the MTD package to include the modifications and new drivers made
by Jason Gunthorpe, and also the current version of my DiskOnChip and NFTL
code. 

It's available at:
	ftp://ftp.linux-mtd.infradead.org/pub/mtd/mtd-19990809.tar.gz

It should contain working drivers for:
	slram		- uncached system memory
	doc1000		- The old DiskOnChip 1000 and ISA flash cards.
	doc2000 	- DiskOnChip2000 (not yet Millennium)
	octagon-5066	- Memory-mapped flash found on a Single Board Computer
	vmax301 	- Likewise.

The devices are presented to the user by default as a character device. 
However, three block devices are available:
	
	ftl		- The original FTL filesystem, as used by PCMCIA
	nftl		- The new (NAND) FTL system, for the DiskOnChip
	mtdblock	- Direct block device access to the MTD

For some reason, the mtdblock_request routine seem to never be called. I'm 
obviously doing something stupid, so I'll let one of you tell me why that is :)

Also included is Jason's FFS2 implementation. The bootloader stuff is also 
present, but commented out in the top-level Makefile because I haven't yet 
upgraded my as86. I'd prefer it if we could make this work without 
bleeding-edge utilites. Jason, is that possible?

Soon, I'm intending to merge Alexander Larsson's 'flash.diff' for onboard 
CFI-compliant memories. Volunteers to do that would be appreciated, because it 
would let me concentrate on completing the DiskOnChip and NFTL code.

Happy Hacking.
