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]
