"Standard" Practice for config of SanDisk compact pci memory for 405gp ppc

[Laurent Mohin]

Hello Jerry,

I think the easiest way to control a Sandisk compact flash card is in true
IDE mode.
We developed our own custom board based around a 405GP (or 405GPr) chip and
an intel 82371 Southbridge. The southbridge provides 2 IDE interfaces on
which you can attach the Compact flash socket.
You will then find all you need in U-boot to load the kernel and file
system from the compact flash.

Our hardware guy is tells me that the SanDisk can be placed
in one of three modes:

1) PC Card Memory Mode
2) PC Card I/O Mode
3) True IDE Mode

The device is going on a custom ppc 405GPr board.

He is also asking me how the device will be accessed

1) on bytes
2) on words
3) or both

I am not much of a hardware person, so I am not even certain if the
question I am asking makes sense.

The main goal is to use u-boot to bootstrap and initialize the board,
and to load the linux kernel/file system from the compact flash.

Does anyone have a reference design for a ppc based SBC with a
san-disc like part on it that runs Linux?

If not, is there a "standard" configuration the the compact flash
is placed on the bus?

Kindest Regards,

Jerry
