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.
