Gentle ping for this patch series.
Any feedback would be appreciated.
Thanks,
Steven

> Subject: [RESEND PATCH 0/6] aspeed: Add AST1040 Caliptra mailbox support
>
> This series adds AST1040 Caliptra MCI mailbox support for the ast1040-evb
> machine.
>
> AST1040 firmware accesses Caliptra through an MCI page aperture. This
> series adds an AST1040 SCU model with the CPTRA page-select registers, a
> mailbox frontend that exposes the Caliptra SRAM and CSR windows, and an
> optional external chardev peer so a Caliptra simulator can service EXECUTE
> requests.
>
> The SoC wiring maps the mailbox SRAM, CSR window and 4 KiB remap
> aperture. The EVB machine also gets a cptra-peer option for linking the
> external peer after the machine is initialized.
>
> The external peer backend is intended for co-simulation with an external
> Caliptra model. The current bring-up backend used for manual testing is
> caliptra-server:
>
>
> https://github.com/stevenlee7189/caliptra-server/blob/main-2.x/README.m
> d
>
> That README includes the server command line, the matching QEMU
> command line, and the guest-side MFWV smoke test sequence used to
> validate the MCI aperture, LOCK/CMD/DLEN/EXECUTE flow, and
> FirmwareVersion response.
> The qtest added by this series does not depend on that repository; it uses a
> socket-backed test peer to validate the QEMU-side protocol and mailbox
> flow.
>
> Resending because some reviewers did not receive the previous email.
> No changes since the prior posting.
>
> Patch layout:
> - patches 1-2 add the AST1040 SCU model and mailbox frontend
> - patch 3 adds the external chardev peer backend
> - patch 4 wires the mailbox into the AST1040 SoC and EVB machine
> - patches 5-6 add qtest coverage and documentation
>
> The qtest covers mailbox lock, execute and completion flow through a
> socket-backed peer, and verifies that SCU CPTRA_PAGE_REG0 remaps the
> MCI aperture between CSR and SRAM pages.
>
> Validation:
> - scripts/checkpatch.pl --branch origin/master..HEAD
> - qtest coverage for the AST1040 mailbox execute path with a
> socket-backed external peer
> - manual co-simulation bring-up with caliptra-server through
> cptra-mbox-peer-extern
