Compact Flash help

[s.balamurugan]

Hello all,

                    This is bala, I am using MPC8360  board and compact 
flash is connected via Local Bus Controller(UPM).
I have the following questions
what are the necessary document to be read for writting the driver for 
compact flash.
What is the relation between compact flash and PCMCIA and PC Card.
What are the CIS structure members.
What are the documents to be read to understand the full concept of 
Compact Flash.

                 Thank u

If you're REALLY interested in knowing everything about Compact Flash,
go here: http://www.compactflash.org/  You can download the spec, which
should help you sleep.

If you want to know how to interface Compact Flash to your Local Bus,
here's a good document.  I'm not intimately familiar with the 8360, but
unless Freescale has changed their LBC design, it should apply:

You shouldn't have to write your own driver for this.  I don't feel
totally comfortable giving you somebody else's code that isn't
necessarily finished, but since you could Google it yourself anyway,
here's a link to one that was put up for comment several months ago.  I
had no part in authoring it and have no idea where it stands regarding
inclusion in the kernel, so please treat it as experimental.  It will
require a bit of work on your part to understand how to specify platform
devices.
