Hi, I use ppcboot to booting linux ,but linux cann't go on when malloc some memory.My board is FADS860T, it has 4M DRAM(in physical 0---3fffff) and 4M SDRAM(in physical address is 03000000-033fffff),when ppcboot run up,i use bdi command find it tell me total memory is 8M which is from 0 to 7fffff.i think ppcboot maped two memory block into one continuous memory block(are i right?).when ppcboot boot linux it pass bdi to linux, so i don't know whether linux kernel understand the memory 0---7fffff is actualy two memory block which is 0----3fffff and 03000000 -033fffff.who can tell me how to understand this.sorry for my bad english.thank you!
