V2 of previous patchset [1], I just rebase the serie and solved the compilation issue.
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 37kB (851096 to 889592 on STM32MP157C-EV1 board for trusted defconfig) but the boot time don't change drastically.
For example on STM32MP157C-EV1 board, trusted boot
1/ Before LOG patchset
STM32MP> bootstage report Timer summary in microseconds (9 records): Mark Elapsed Stage 0 0 reset 621,283 621,283 board_init_f 800,946 179,663 board_init_r 1,272,726 471,780 id=64 1,298,092 25,366 id=65 1,299,997 1,905 main_loop 1,310,785 10,788 id=175
Accumulated time: 57,678 dm_f 69,883 dm_r
After this serie :
STM32MP> bootstage report Timer summary in microseconds (9 records): Mark Elapsed Stage 0 0 reset 626,031 626,031 board_init_f 806,187 180,156 board_init_r 1,280,935 474,748 id=64 1,306,580 25,645 id=65 1,308,484 1,904 main_loop 1,319,262 10,778 id=175
Accumulated time: 57,763 dm_f 69,843 dm_r
=> cost 9ms
2/ With LOG activated at level 8 and bootstage info in __log() function)
+ CONFIG_LOG_MAX_LEVEL=8 + CONFIG_LOG_DEFAULT_LEVEL=6
STM32MP> bootstage report Timer summary in microseconds (10 records): Mark Elapsed Stage 0 0 reset 641,076 641,076 board_init_f 829,569 188,493 board_init_r 1,339,783 510,214 id=64 1,372,315 32,532 id=65 1,374,182 1,867 main_loop 1,544,359 170,177 id=175
Accumulated time: 25,087 log 63,300 dm_f 73,424 dm_r
=> cost is 70ms
3/ after log patchset [2], I gain 20ms
STM32MP> bootstage report Timer summary in microseconds (10 records): Mark Elapsed Stage 0 0 reset 644,372 644,372 board_init_f 827,695 183,323 board_init_r 1,323,756 496,061 id=64 1,354,157 30,401 id=65 1,356,050 1,893 main_loop 1,366,785 10,735 id=175
Accumulated time: 24,837 log 59,676 dm_f 70,916 dm_r
PS: accumulated time is strange here
