[ARM] 4461/1: MXC platform and i.MX31ADS core support This patch adds the foundation pieces for the Freescale MXC platforms, including i.MX2 and i.MX3 based systems. The bare-bones MX31 support in this patch boots to the rootdev panic with 8250 serial console configured "console=ttyS0,115200". It assumes that Redboot is the boot loader.

ARM: imx: fix sync issue between imx_cpu_die and imx_cpu_kill There is a sync issue with hotplug operation. It's possible that when imx_cpu_kill gets running on primary core, the imx_cpu_die execution on the core which is to be killed hasn't been finished yet. The problem will very likely be hit when running suspend without no_console_suspend setting on kernel cmdline. It uses cpu jumping argument register to sync imx_cpu_die and imx_cpu_kill. The register will be set in imx_cpu_die and imx_cpu_kill will wait for the register being cleared to actually kill the cpu.

Instead, it should be done in .cpu_kill which runs on the thread (another cpu) that asks for shutting down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die, so that we can get a more stable cpu hot-plug operation.
