I have it as,

#define CFG_BOOTMAPSZ    ( 8 << 20 )    /* Initial
Memory map for Linux */

I have linux-2.4.22 from www.ppckernel.org, is there
any kernel configuration I need to add ?

I got one prebuilt ramdisk from ftp.denx.du
"sime-ramdisk.PPCBoot" and this worked fine. But it
dosent have any utilities that I would like to use.

I am also trying to use busybox-0.60.5 but when I
build a ramdisk out of that the kernel dosent
recognise that.

Warm Regards
Raghu.
