Daniel Barlow 46991e2761 aarch64 ram starts at 0x40000000 2023-11-05 15:33:10 +00:00
Daniel Barlow a135cb1217 introduce lim, the liminix library 
so far we have lim.parseInt, which parses an integer from a string
with optional base-selecting-prefix (e.g. 0755, 0x12ab)
 2023-11-05 15:13:06 +00:00
Daniel Barlow 863045b86b added hardware.ram.startAddress config 
it's not 0 on arm32, so this will be useful for qemu

Daniel Barlow e6ef4f78bb "ubimage" module contains ubifs image + instructions 
Presently either you run this from U-Boot or you figure out for
yourself how to kexecboot into a recovery system :-)

Daniel Barlow f3225c2bd5 delete dup outputs.systemConfiguration 
perhaps this should go into initramfs.nix not jffs2.nix
 2023-10-19 10:09:08 +01:00
Daniel Barlow 8798ee9830 partial fix for timeout handling 
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

reverting to the commit before this one.
