x86: Move the i386 code into its own directory

2017-02-06T03:38:46Z

Much of the cpu and interrupt code cannot be compiled on 64-bit x86. Move it into its own directory and build it only in 32-bit mode. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Move MP initialization codes into a common place

2015-07-15T00:03:16Z

Most of the MP initialization codes in arch/x86/cpu/baytrail/cpu.c is common to all x86 processors, except detect_num_cpus() which varies from cpu to cpu. Move these to arch/x86/cpu/cpu.c and implement the new 'get_count' method for baytrail and cpu_x86 drivers. Now we call cpu_get_count() in mp_init() to get the number of CPUs.

x86: Add multi-processor init

2015-04-30T22:13:38Z

Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader. Add the required support to U-Boot to init additional APs. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
