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
Do you know which symbol(s) grew in here ?
- 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?
Try and set CONFIG_BOARD_SIZE_LIMIT and CONFIG_SPL_SIZE_LIMIT for this
board, that would trip build error if the size grows too large.
