powerpc/helas403 linkcmd question

Hello Gene,

hmmm, I should know that because I adapted the 
ppc403 support to my helas403 board, but actually... 
I have no idea.

I guess, I used the first 64kByte for a debug 
monitor and therefore relocated the vectors a bit up 
in the memory map. The PPC4xx family has the ability 
to relocate the vectors on any 64k boundary.

I don't see any reason to leave it there, so feel 
free to remove the ".fill" section. Just make sure 
you move the ".vectors" section by 64k.

wkr,
Thomas.
