I tried this patch series on v3.7-rc7 with CONFIG_MACH_KZM9G_REFERENCE=y.
It boot up correctly with rootfs on SD card. It works good for following devices
- serial port on /dev/ttySC4
- SD card on /dev/mmcblk0
- micro SD card on /dev/mmcblk1
- eMMC on /dev/mmcblk2
I found /dev/i2c-0 seems not to work correctly. "i2cdump" command fails like this.
# i2cdump 0 0x40
No size specified (using byte-data access)
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0, address 0x40, mode byte
Continue? [Y/n]

I quited the command by ^C.
When I try the same on v3.7-rc7 without CONFIG_MACH_KZM9G_REFERENCE=y
"i2cdump" command does not time out and shows some data.
