[PATCH 4/5] board_init_r(): use static calls

Jerome Forissier jerome.forissier at linaro.org
Tue Dec 17 16:59:35 CET 2024


Replace the init_sequence_r function array by direct calls.
bloat-o-meter stats before/after on u-boot.bin for configuration
xilinx_zynqmp_kria_defconfig are the following:

- With LTO:
add/remove: 85/126 grow/shrink: 9/23 up/down: 19228/-20547 (-1319)
Total: Before=1067523, After=1066204, chg -0.12%

- Without LTO:
add/remove: 0/24 grow/shrink: 1/0 up/down: 488/-1124 (-636)
Total: Before=1118923, After=1118287, chg -0.06%
