I'm working on an mpc8548 based board and recently I've encountered a
problem, whereupon kernel crashed each time module loading is attempted. I
traced the problem to the fact, that vmalloc_exec was setting incorrect
page attributes on allocated pages. This, in turn, happened because I
specified "Large physical address support" in the Kconfig, leading to
CONFIG_PHYS_64BIT and friends being set.
It appears that having this option set on e500 pulls in incorrect headers
and otherwise not working. CPU, however, has support for 36b physical
addressing, which qualifies as "Large physical address".
So, the obvious question is, what is the current status of large physical
address support on e500? Is it a problem in current git version or is it
not ready yet?
Thanks.
