Applying MTD to 2.2.x kernel, with more info

Tue Aug 14 09:02:57 EDT 2001

Hi again,

sorry to bother you again. The patch help me to go a little further, but it
does not compile all the way through ... I have added the compile output
after my message ...

An other question, do you know wich option I have to set to support this
flash :

	Flash STMicroelectronics Part number M58LW064A150N1T, package
TSOP-56
	manufacturer code = 0x20h
	device code = 0x17h

For the moment its not the important part ... I have to be able to compile
the kernel with MTD support after that I will find wich params I need to
make it to work ... but for the moment I cant compile the driver. For the
moment I have added the CFI support and I have set the debug level to 3
thats all.

If you can see it, but it's not there, it's virtual. 
If you can't see it, but it is there, it's hidden. 
It you can't see it and it isn't there, it's gone.
