This patch-set migrates several stm32 drivers to API compatible with logging features (use dev_...() or log_...() function) and activate the logging features in STM32MP15 boards.
The size of U-Boot increased by 19kB (933026 to 952830 on STM32MP157C-EV1 board for basic defconfig) but the boot time don't change drastically.
For example on STM32MP157C-EV1 board:
1/ Before LOG patchset
Timer summary in microseconds (12 records): Mark Elapsed Stage 0 0 reset 224,514 224,514 SPL 961,170 736,656 end SPL 964,006 2,836 board_init_f 1,186,986 222,980 board_init_r 1,651,379 464,393 id=64 1,674,463 23,084 id=65 1,675,164 701 main_loop 4,025,806 2,350,642 id=175
Accumulated time: 55,064 dm_f 66,749 dm_r 88,796 dm_spl
2/ With LOG activated (after this patchset)
Timer summary in microseconds (12 records): Mark Elapsed Stage 0 0 reset 227,142 227,142 SPL 984,585 757,443 end SPL 987,579 2,994 board_init_f 1,210,091 222,512 board_init_r 1,673,354 463,263 id=64 1,696,073 22,719 id=65 1,696,775 702 main_loop 5,443,104 3,746,329 id=175
Accumulated time: 62,154 dm_f 66,264 dm_r 89,376 dm_spl
For information even with all trace embbeded in U-Boot but not activated, MAX_LOG_LEVEL=8 and LOG_DEFAULT_LEVEL=6
Size increase by 190KB (952830 to 1147918) but boot time is stable (1,748s vs 1,696s).
