arm builds show the following warning.
arch/arm/Kconfig.debug:1576:warning: ignoring unsupported character '>'
This is due to config DEBUG_UART_8250_WORD bool "Use 32-bit accesses for 8250 UART" depends on DEBUG_LL_UART_8250 || DEBUG_UART_8250 depends on DEBUG_UART_8250_SHIFT >= 2
The unsupported operand causes DEBUG_UART_8250_WORD to be disabled if DEBUG_UART_8250_SHIFT is larger than 2, which is not what is intended.
Fixes: 0b4cccbec606 ("ARM: debug: add support for word accesses to debug/8250.S") Cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- v2: Instead of configuring DEBUG_UART_8250_WORD only if DEBUG_UART_8250_SHIFT == 2, set it if DEBUG_UART_8250_SHIFT is neither 0 nor 1.
