cover mx25: NAND support

This patch series add support for NAND chips on the i.MX25 platform, using the recently merged support for this platform in the mxc_nand driver.

I tested this code on the i.MX25 PDK platform.

Should these patches be visible in the mxc-master of the imx/linux-2.6.git tree? I don't see them there.
