Procedure for bumping the optee branch to a recent Linux? #104

Closed jneuhauser closed 1 year ago

jneuhauser commented 1 year ago

Hello dev's,

in order to add our recent added STM32MP15 DHSOM based boards to OP-TEE/build and OP-TEE/manifest, it would be good to upgrade Linux to 5.18 or even better to 5.19.

Before creating a pull request, I would like to ask what is the preferred approach to this process?

The possible solutions to fully support our boards are:

  1. backport needed patches to 5.17 and define OP-TEE resources.
  2. bump Linux to 5.18 or even better to 5.19 and define OP-TEE resources

Thanks in advance, Johann

Hello @jneuhauser,

Short answer: 2.

I take care of rebasing the optee branch of this repo periodically, usually shortly before OP-TEE release time. The optee branch is a convenience for the dev/test environment (which is as you mentioned, the build and manifest Gits). In principle we only want DT patches in here which are not acceptable upstream -- in any case, the less changes compared to upstream the better. It does happen that we merge features here temporarily but any OP-TEE driver patch should really go to the LKML directly. So I will rebase onto 5.19 ; when done, if you would like to submit DT patches for your platform please create a PR here.
