[ECOS] help compiling redboot : linker problem !!!!

[Thomas TESTASECCA <thomas dot testasecca at etictelecom dot com>]

hi all,

I work on a cdb89712 evaluation board to embedd a linux kernel (armlinux 
kernel 2.4.rmk2.rayl1)
previously i used hermit bootloader, but it don't supports booting from 
cramfs, jffs2 .... so i decided to
port redboot to my target (it seems relatively easy because 7212 & 7211 
are supported, flash driver is present (28f320b3) ....)
Ok, so firstly i decided to compile for the edb7212, you know just to 
see how it works ....
But i've got a problem : the linker complains about overlapping segments 
.... (this is the rodata which overlaps others), it complains about "no 
memeory region specified for xxxxxxx", and relocation truncated ......

this is what i do :
ecosconfig new ecb7xxx
ecosconfig import edb7212_redboot_ROM.ecm
ecosconfig tree
make

and the result :
