which copies the init stuff (whatever it is) from store to /persist
instead of making liminix-rebuild have to know what the files are.
This is principally to ease making a system configuration in /mnt or
similar when operating in a rescue/recovery scenario, and we
don't want to liminix-rebuild because it will reboot
This is for MIPS. I spent a while investigating why the second virtio
net device doesn't function in qemu mips malta u-boot, but with no
success. Use the first one instead.
1) "Unknown transfer id" message was because the local variable "tid"
is not a transfer id, it is a sequence number - so the check was
actually comparing expected vs actual acknowledged sequence number,
not TID. It's still a problem if we get the wrong one, but it
indicates a lost packet (so we should resend) not a packet that was
sent from somewhere else.
2) if the ACK packet has not been received, our retry should involve
_resending_ it, not just trying to wait for it again.
3) I have removed the timeout condition for terminating the resend
loop, because in practice (assuming both ends have the same timeout
setting) all it did was ensure that the loop only ran once. The
timeout is supposed to regulate how long we wait for before retrying
(it doesn't do this, we wait indefinitely), not how long we wait for
before giving up.
- patch dtb to add reserved-memory stanza for the phram device to use
(aarch64 does not accept memmap= command line option)
- patch phram driver to use memremap() instead of ioremap() as
ioremap can't be used for system ram on arm devices
