From: Joao Lima <joao.lima@hbkworld.com>

This patch series updates OpenOCD to support direct memory access (dmem)
via SWD emulation for Texas Instruments AM64x and J784s4 platforms.

Changes include:
1. Version bumps:
   - openocd: 91bd431 -> 66ea461
   - jimtcl: fcbb449 -> f160866
   - libjaylink: 9aa7a59 -> 0d23921

2. Platform support patches:
   - Add SWD native configuration files for AM64x and J784s4 boards
   - Configure DMEM access parameters in ti_k3.cfg for direct memory operations
   - Set up DAPBUS debugger and emulated AP descriptions

3. Build configuration:
   - Enable dmem adapter driver (--enable-dmem)
   - Enable internal jimtcl (--enable-internal-jimtcl)
   - Add both features to default PACKAGECONFIG

This enables self-hosted debug configurations where OpenOCD runs on one of
the CPUs inside the SoC.

Thanks for the patchset, Please rebase it on latest master branch or 
master-next branch and resend. While resending send the whole series
together with git send-email *.patch or something so tools like 
patchwork and lore can record this as a series.

Thanks for the feedback.

I'm currently working on top of:
URI:    https://git.openembedded.org/meta-openembedded
Branch: scarthgap
Commit: e8fd97d86af86cdcc5a6eb3f301cbaf6a2084943

Should I rebase my patch series on top of the latest master (or master-next) branch, even though I'm targeting the scarthgap branch?
As this is my first submission to the project, I want to ensure I'm following the correct process.

Thanks for the submission tip.

Yes you are right and should send on top of master or even master-next.

If the patchset does not include breaking changes they can be backported to
the stable branch,
this last criterion will be the responsibility of the maintainer.
For example, major bumps in the version are generally not accepted to be
backported.

Jose

If a change is needed in the version in master branch then it goes there
first and then back ported to releases

Hello Khem and Jose,

Thanks for the reply.

I have already rebased my patch series on top of the latest master and committed the latest changes.
---
Khem, I submitted the series as intended.
However, I submitted it twice, because the first time, for some reason, it took longer than expected to appear in the meta openembedded layers patch list (https://patchwork.yoctoproject.org/project/oe/list/?submitter=1534).
Only the last series should be considered.

Thanks for your help.
