Dear Community,

I'd like to share with you some thoughts about growth of u-boot's
binary size for SPL and u-boot proper.

Board: XEA
SoC : imx287 (still in active production)
Problem: SPL size constrained to ~55 KiB (This cannot be exceeded).
Board design constraints u-boot proper size to less than ~448
KiB

When XEA was added (2019.07):
- u-boot.sb (SPL): 37 KiB
- u-boot.img : 401 KiB

Now (2024.04):
- u-boot.sb (SPL): 40 KiB
- u-boot.img : 427 KiB

(With a _lot_ of effort put to reduce the size)

Hence, the question - would it be possible to take more concern about
the binary size growth?

Maybe CI could catch patches, which enable by default some features and
the size is unintentionally increased?

I'm open for any feedback and thoughts on "stopping" the binary size
increase.
