[U-Boot-Users] porting u-boot: to what extent must the flash.c / u-boot.lds be customized?

[Peter Asemann]

I've been asked to measure the approximate time I'll need to finish 
porting u-boot.

I have developed optimistic beliefs about most of the things I still 
need to do, but I almost didn't touch the flash.c and the u-boot.lds yet.

Is it probable I'll be able to "copy&paste"-program most of the flash.c 
because I'll use rather often used AMD AM29LV320D chips?
Is the u-boot.lds difficult to modify?
