UART pinctrl for serial is typically applied multiple times: - in external TPL or in TPL for DEBUG_UART in board_debug_uart_init() - in SPL for DEBUG_UART in board_debug_uart_init() - in SPL using pinctrl from DT - in pre-reloc phase using pinctrl from DT - after relocation using pinctrl from DT
This series change bootph props for the UART pinctrl to not include them in pre-reloc phase to save some boot time: - Radxa ROCK Pi S (RK3308): ~80 ms - Radxa ZERO 3W (RK3566): ~120 ms - Radxa ROCK 5B (RK3588): ~150 ms Similar change has already been applied for RK3328 and RK3399 boards. The change for PX30 has not been runtime tested, and only include change for uart2, not uart0 and uart5 used on two of the supported px30 boards.
