<br>we can conclude that it uses ata-generic SATA/PATA controlelr driver which controls PCI-based IDE-controller where we can plug in our CF card...Am I right???<br>But in our design we don't use any controller we directly connects CF card to local bus where UPM controls it..<br>
Can you please explain how the interface is implemented in MPC8349..<br><br><pre class="done" id="97/0b/e6e9411e1792a01199c69b29f9235db64018_3/0"><br></pre><br><div class="gmail_quote">On Mon, Aug 2, 2010 at 7:18 PM, <a href="mailto:linuxppc-dev@lists.ozlabs.org">linuxppc-dev@lists.ozlabs.org</a> wrote:<br>

</div>CF IDE support was already implemented for MPC8349EmITX boards<br>
with a bit of help from UPM (User-Programmable Machine), so<br>
you can do the same for MPC8360.<br>
<br>
UPM is programmed in U-Boot, u-boot/include/configs/MPC8349ITX.h<br>
(CONFIG_SYS_BR3_PRELIM stuff), and<br>
u-boot/board/freescale/mpc8349itx/mpc8349itx.c (UPMATable).<br>
<br>
For linux part, see arch/powerpc/boot/dts/mpc8349emitx.dts (pata<br>
node), and drivers/ata/pata_of_platform.c.<br>
<br>
For HW side, you can find MPC8349EmITX schematics on Freescale<br>
site (last time I checked, no registration was required).<br>
