[Barrelfish-users] mmap in menu.lst.scc

[Simon Peter]

Hi Zhiquan,

LUT mappings are actually hard-coded in the RCK driver in the Barrelfish 
CPU driver (rck.c). The mmap lines in the menu.lst.scc mirror that 
configuration, but only advise other parts of the OS on where memory is. 
Specifically, they provide the BIOS memory map to the CPU driver, which 
would otherwise be provided by GRUB on x86, and their parameters are 
exactly those.

Hope this helps,
Simon
