From 50f2de61269bbe2f40bead1969a9594fa8599b93 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 14 Sep 2012 14:14:45 +0800 Subject: ARM: imx: include hardware.h rather than mach/hardware.h It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h. The files in mach-imx/devices will need to include "../hardware.h".

Different board design may choose different port as debug uart. For example, imx6q-sabresd uses UART1, imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than bloating DEBUG_LL choice list with all these uart ports, the patch introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.
