From 4ad625d466389b016a9aec425b3dc2d82adc43df Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Wed, 12 Dec 2012 18:54:01 +0800 Subject: ARM: imx: use separated debug uart symbol for imx31 and imx35 It's improper to use combined symbol DEBUG_IMX31_IMX35_UART for imx31 and imx35, because imx31 has 5 UARTs while imx35 only has 3. So later when we add UART port selection for DEBUG_IMX31_IMX35_UART, we will have problem. Use separated Kconfig options for imx31 and imx35 debug uart selection.

The 'range' of the Kconfig option gets dropped, as users looking at the option must know the uart number on his board. The bottom line is that the build system will report an error if an invalid port number is picked for given SoC. The header arch/arm/include/debug/imx-uart.h is created to accommodate all the uart base addresses. And the header will also be used for other low-level debug facility later.
