[PATCH V7 0/7] Low Power Mode: Package TIFS Stub in BeaglePlay
Hello,
This series aims to add documentation around the boot flow and tispl packaging details regarding the TIFS Stub. While at it, also refactors the k3 common docs to add more labels to provide more granularity on how we include chunks from common docs into SoC specific docs.
This series also includes the binman related changes required to package TIFS Stub to support Low Power Modes on BeaglePlay and phycore-am625 SOM.
Changelog: ********** * fixup wording of tifs stub docs as per comments from Nishanth on v6. * Add packaging of tifs stub in phycore am62 as well. (Build-tested) * Minor fixup in am64-phycore docs include sysfw
Link to v6: https://lore.kernel.org/all/20240719070312.3771755-1-d-gole@ti.com/

* Add documentation to briefly explain the role of TIFS Stub in relevant K3 SoC's. * Shed light on why TIFS Stub isn't package with the DM firmware itself. * Modify the platform docs wherever the TIFS Stub documentation applies. * Also, refactor and add a few new labels to help split the firmware documentation chunks.

Sure, I am ok having this added, just adds the required changes to verdin-am62 in this patch.
Thanks, Francesco
Since AM62x, AM62P and AM62A all use similar boot flows and their low power mode s/w ARCH is also similar in the way that they make use of the TIFS Stub, update their documentation to show where TIFS Stub is.

Add support for packaging the TIFS Stub as it's required for basic Low Power Modes like Deep Sleep. The reason it is packaged using binman and not inherently as part of the DM firmware is because for HS devices, customer owns the customer key and only customer has access to it. DM is release by TI, Since TI doesn't have access to the customer key it cannot have a component that is signed by customer key. Hence, it's left as part of binman to be signed and packaged.

Build procedure

Add support for packaging the TIFS Stub as it's required for basic Low Power Modes like Deep Sleep. The reason it is packaged using binman and not inherently as part of the DM firmware is because for HS devices, customer owns the customer key and only customer has access to it. DM is release by TI, Since TI doesn't have access to the customer key it cannot have a component that is signed by customer key. Hence, it's left as part of binman to be signed and packaged.
While at it, also make sure it's documented in phycore-am62x
