You dont have to modify the kernel for that. When configuring (menu
config) the kernel in the general setup
set the kernel command line to root=/dev/flash3 or something like that.
This way you dont
have to use any ramdisk as initrd. kernel will crib that it doesnot find
initrd but will continue.
Take a look at the mtd drivers or the flash_mem.h in drivers/block ,
depending on what version
of the kernel you are using for flash partitioning. For ex I use 2.4.0
test8 rm2 np2,
my flash partition is as follows, 256K (blob), 768K (kernel), rest
(ext2). So my command line will be
root = /dev/flash2. Hope this helps.
