i.MX: UART support Implement the Freescale i.MX UART. This uart is used in a variety of SoCs, including some by Motorola, as well as in the Freescale i.MX series. This patch gives only a `bare-bones' implementation, enough to run Linux or OKL4, but that's about it.

i.MX31: Clock Control Module For Linux to be able to work out how fast its clocks are going, so that timer ticks come approximately at the right time, it needs to be able to query the clock control module (CCM). This is the start of a CCM implementation. It currently knows only about the MCU, HSP and IPG clocks --- i.e., the ones used to feed the periodic and general purpose timers.
