Simon Glass	d116b53f87	x86: Add comments to the SIPI vector ... The Intel SIPI (start-up inter-processor interrupt) vector is the entry point for each secondary CPU (also called an AP - applications processor). The assembler and C code are linked, so add comments to indicate this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>	9 years ago
Bin Meng	ef1683d5c3	x86: Pass correct cpu_index to ap_init() ... In sipi_vector.S, cpu_index (passed as %eax) is wrongly overwritten by the ap_init() function address. Correct it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>	10 years ago
Simon Glass	45b5a37836	x86: Add multi-processor init ... 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.
