[U-Boot-Users] CF card in memory mapped mode without PCMCIA controller

[U-Boot-Users] CF card in memory mapped mode without PCMCIA controller

[Andriy Korud]

Hi,
I'm going to use CF card in memory-mapped mode (not true IDE because HS
is required), but without PCMCIA interface chip (necessary signals will
be software/glue-logic generated). 
Will U-Boot like this? Or, will it be difficult to port it to use such
mode? 
Maybe somebody has an example of such solution? 

Thank in advance,

Andriy:

I previously pointed you to the Sandburst Metrobox and Karef ports.  You 
had mentioned (on the linuxppc-embedded)
that you're using ppc4xx.  The SB Metrobox and karef are 440GX based boards.

We use FAT for loading the kernel, then the kernel mounts an ext3 
partition on the cf for its root fs.

Take a look at include/configs/METROBOX.h and board/sandburst/*
