I don't like this very much because I think that shutdown_barebox should
be the last thing before jumping to the kernel. Also it makes starting
of the kernel potentially slower as we execute code with caches
disabled.
BTW I don't understand why the zero page is faulting in your case
anyway. You have SDFAM at 0x0, right? So we have
vectors_init() -> sets zero page to faulting
for_each_memory_bank()
create_sections(); -> should set the zero page accessible again
if we have a SDRAM bank at 0x0
Am I getting something wrong here?
