[PATCH v2 2/5] board_init_f(): use static calls
Jerome Forissier
jerome.forissier at linaro.org
Wed Dec 18 16:53:55 CET 2024
Make static calls instead of iterating over the init_sequence_f arrays.
Tested on a KV260 board (xilinx_zynqmp_kria_defconfig).
- With LTO enabled, the code size reported by bloat-o-meter is 1200
bytes less (-0.11%)
- With LTO disabled, the code is 594 bytes smaller (-0.05%)
- Execution time does not change in a noticeable way
