Hi Andreas,
support. Is there a strict requirement (from the kernel's early
startup and mem_init POV) that the kernel has to reside in the first
bootinfo memory chunk?
It is a requirement that the kernel is mapped at virtual address zero
since it is not relocatable.
That much I understand - but can we tweak the bootinfo to report the
chunks in physical address order? What I mean to say is - does the
first bootinfo chunk get mapped at virtual address zero always, or is
there some check to see what physical address corresponds to the
kernel segment?
From what I can see the first mem_info struct is always mapped at VA 0
which is done in paging_init() in mm/motorola.c
