[U-Boot-Users] MPC83xx: CF in True IDE mode

[Yogi]

Is there support for CF access in true IDE mode for
83xx with Reiser File system ?
Thanks
Yogi

You are asking two different questions. I dont know if u-boot  
supports reiserfs.  As far as CF access in true IDE mode how are you  
planning on connecting CF to the 83xx?

The basic IDE support in u-boot provides enough functionality for CF  
to work on 83xx.

Hi Yogi,

ReiserFS should be no problem since it is supported by u-boot.

For CompactFlash using TrueIDE-Mode you'll need an IDE/ATA interface, which is 
not natively present on MPC834x processors. There's a LocalPlusBus with wich 
you can do standard memory mapped CF access. The "CF storage" cards do 
support this mode also. But it will require some glue-logic.


regards,
Andr?

[U-Boot-Users] MPC83xx: CF in True IDE mode

[Joao, Nuno]

	We're using a CF card in TrueIDE mode, on a board with u-boot
	and MPC8541E.

	A CPLD maps the CF bus (only the signals needed for IDE mode)
	into MPC's memory map; this makes the "IDE physical" interface.
	UPM machines are used for the accesses timing. 2 chipselects
	are also used, one for the "normal" register file and another
	for the "alternative register file".

	u-boot's "ide" command is used; it was only changed in the
	register access routines, because of different address
	calculation and endianess.

	You have to be careful when interfacing the CF card (or any
	IDE device) with the MPCs. Keep in mind that register 0 (the
	data register) is accessed at address 0 and is 16 bit wide;
	the remaining registers are accessed in the next consecutive
	addresses (1, 2, ...), but are 8 bit wide.

	Best Regards
