x86: Set APs' req_seq to the reg number from device tree

2015-08-14T15:50:12Z

Multiple APs are brought up simultaneously and they may get the same seq num in the uclass_resolve_seq() during device_probe(). To avoid this, set req_seq to the reg number in the device tree in advance. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Add some missing global_data declarations in files that use gd

x86: Remove inline for lapic access routines

2015-07-15T00:03:17Z

Remove inline for lapic access routines and expose lapic_read() & lapic_write() as APIs to read/write lapic registers. Also move stop_this_cpu() to mp_init.c as it has nothing to do with lapic. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Move lapic_setup() call into init_bsp()

2015-07-15T00:03:16Z

Currently lapic_setup() is called before calling mp_init(), which then calls init_bsp() where it calls enable_lapic(), which was already enabled in lapic_setup(). Hence move lapic_setup() call into init_bsp() to avoid the duplication. Signed-off-by: Bin Meng Acked-by: Simon Glass

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
