2016-03-17x86: Add comments to the SIPI vectorSimon Glass
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>
2015-04-30x86: Add multi-processor initSimon Glass
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 <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
