[meta-ti][master/scarthgap][PATCH] conf: machine: am62axx: Exclude tiboot3.bin for GP

[Chirag Shilwant]

* The GP variant of SK-AM62A-LP is no longer tested.
Hence, don't include it under IMAGE_BOOT_FILES to ensure
tiboot3-am62ax-gp-evm.bin is not packaged inside /boot
partition of wic image

* Is it still being built?

* Also, what about other BSPs, e.g. 6.1?

* What about derivative or customer platforms, besides SK-AM62A-LP? I.e. you 
are modifying the entire am62axx SoC family, which is supposed to be shared 
by multiple platforms in the AM62A SoC family.

The GP part was built during the device bring-up (~ 2years back)
Apparently GP samples are limited to TI internal. Hence, the logic to
deploy tiboot3 for it was added in meta-ti-bsp at that time to support
internal development.

Post device APL, all TI internal development is moved to HS-FS part.
(Ideally, this logic of deploying tiboot3 for GP should have been 
removed at that time)

 From customer / 3rd party SOM pov, all receive HS-FS part by default 
from TI.
So, they shouldn't be affected if meta-ti-bsp no longer deploys 
|tiboot3-am62ax-gp-evm.bin|

In meta-ti-bsp, am62axx-evm (which represents SK-AM62A-LP) is the only
machine which utilizes AM62A SoC.

& for customer platforms...as mentioned above, ideally they shouldn't be 
affected
as GP parts weren't shipped to them

For reference, we can checkout prebuilt-images folder of phyCORE-AM62A [0]

Chirag,

Thanks for clarifying.

Probably should rephrase the commit message with a brief explanation.

Instead of:

The GP variant of SK-AM62A-LP is no longer tested.

Something like:

The GP variant of AM62A SoC was only used internally for initial device 
bring-up and is not publicly available.
