Yes, we resolved this problem.
First of all there was problem with ramdisk - it should have a header.
We used this makefile to generate proper ramdisk.
initrd.mk:
STAGING_DIR=.
TARGET_DIR=root
#############################################################
#
# make an initrd image - assumes all the tools are available
#
#############################################################
# this comes from the u-boot project!!
MKIMAGE=/usr/bin/mkimage
MNTPOINT:=$(STAGING_DIR)/mnt
$(MNTPOINT):
mkdir -p $(MNTPOINT)
#############################################################
#
# Build the ramfs root filesystem image
#
#############################################################
ramdisk.image.gz: $(TARGET_DIR) $(MNTPOINT)
dd if=/dev/zero of=ramdisk.img bs=1024 count=2048
/sbin/mkfs.ext2 -N 500 ramdisk.img -F
sudo mount -o loop ramdisk.img $(MNTPOINT)
cp -R $(TARGET_DIR)/* $(MNTPOINT)
sudo umount $(MNTPOINT)
cat ramdisk.img | gzip -9 -c > ramdisk.image.gz
rm -f ramdisk.img
initrd: ramdisk.image.gz
$(MKIMAGE) -n 'Simple Ramdisk Image' \
-A ppc -O linux -T ramdisk -C gzip \
-d ramdisk.image.gz initrd
rm -f ramdisk.image.gz
Call it "make -f initrd.mk initrd"
You should get a initrd file as output of this makefile - this what you
want. You just need to pick up a mkimage from u-boot project.
Also you should pass clocks in HZ. For this make sure that you have
undefined in u-boot clocks_in_*mhz* environment variable. Use printenv
in u-boot to make sure it is not present.
When you will get to the point when you start a busybox (if you use one)
then it could stuck if /dev has no all nodes required.
Hopefully this helps.
