[U-Boot-Users] Re: [PATCH] Make System IO Config Registers board configurable on MPC83xx

[David Updegraff]

Now I wonder if a similar thing might be done in start.S, so that the 
[re] mapped size of flash complies with what is defined in the config 
file?  Either from flash size, or from the _PRELIM_* settings that are 
already there?  Instead of current status quo of hardwired to 8M flash size?
