RE: Strange ARCH_HAS_STACK_PROTECTION behavior

Hi,

In this case, I think the warning for UART_NRFX and UART_CONSOLE causes the build error if you use the default custom board files which don't include UART. You can compare the board files of the custom board and nRF52833DK.

warning: UART_NRFX (defined at drivers/serial/Kconfig.nrfx:6) has direct dependencies (DT_HAS_NORDIC_NRF_UART_ENABLED || DT_HAS_NORDIC_NRF_UARTE_ENABLED) && SERIAL with value n, but is currently being y-selected by the following symbols:
 - SECURE_BOOT_DEBUG_UART (defined at /home/yura/ncs/v2.4.2/nrf/subsys/bootloader/Kconfig:222), with value y, direct dependencies <choice SECURE_BOOT_DEBUG_BACKEND> (value: y), and select condition <choice SECURE_BOOT_DEBUG_BACKEND> (value: y)

warning: UART_CONSOLE (defined at drivers/console/Kconfig:43) has direct dependencies SERIAL && SERIAL_HAS_DRIVER && CONSOLE with value n, but is currently being y-selected by the following symbols:
 - SECURE_BOOT_DEBUG_UART (defined at /home/yura/ncs/v2.4.2/nrf/subsys/bootloader/Kconfig:222), with value y, direct dependencies <choice SECURE_BOOT_DEBUG_BACKEND> (value: y), and select condition <choice SECURE_BOOT_DEBUG_BACKEND> (value: y)

Even using nRF52833DK to build with your configs, it would get the HW_STACK_PROTECTION warning. However, it would not cause the build to fail.
