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:
**********
No changes other than picking up R-by's and rebased.

Link to v7:

* 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. This will make it easier to include them one by
  one wherever applicable

Since AM62x, AM62P and AM62A all use similar boot flows and their low

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.

* Include the actual common documentation about the TIFS Stub and role
  it plays to enable Low Power Modes in the platform.
* Add the AM62x boot flow to show at which point the TIFS Stub actually
  gets loaded.
* Mention the TIFS Stub in the TISPL image format.
