[U-Boot-Users] Newbie... still stuck with RAM disk

[Luke Fimmerzane]

Finally got access to hardware again. So here's the full o/p from my ARM 
target.
Still trying to get a root file system on a RAM disk. Without any success.
Here's o/p from my booting.... Again apologies if its in-appropriate. I'm 
absolutely stuck!

The RAM disk is programmed into FLASH at 0x8200000. The kernel is tftpeed to 
RAM at 0x30300000

my bootargs are root=/dev/ram

A couple of questions before I'm roasted.......

-> Do I need CONFIG_SETUP_MEMORY_TAGS enabled
-> Do I need CONFIG_INITRD_TAG enabled
-> Should CONFIG_DEVFS_FS be enabled in kernel?
-> Should CONFIG_DEVFS_MOUNT be enabled in kernel
-> When running mkimage for RAM disk what relevance are load and entry 
addresses. My
'Karim Yaghmour' book says not needed.
-> Do I need to specify 'initrd='
-> Do I need to specify 'initrd_start='

Sorry for appearing dumb but there are so many combinations...... and I have 
already tried so many
my head is spinning.

Thanks,
Luke
