x86: Update microcode for secondary CPUs

2016-03-17T02:27:25Z

Each CPU needs to have its microcode loaded. Add support for this so that all CPUs will have the same version. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Record the CPU details when starting each core

2016-03-17T02:27:25Z

As each core starts up, record its microcode version and CPU ID so these can be presented with the 'cpu detail' command. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Tidy up mp_init to reduce duplication

2016-03-17T02:27:23Z

The timeout step is always 50us. By updating apic_wait_timeout() to print the debug messages we can simplify the code. Also tidy up a few messages and comments while we are here. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: fix memalign() parameter order

2016-02-21T05:42:51Z

Purely by code inspection, it looks like the parameter order to memalign() is swapped; its parameters are (align, size). 4096 is a likely desired alignment, and a variable named size sounds like a size:-) Fixes: 45b5a37836d5 ("x86: Add multi-processor init") Signed-off-by: Stephen Warren Reviewed-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Bin Meng

x86: qemu: fix cpu device in smp boot

2016-01-13T04:20:16Z

Currently, when booting with more that one CPU enabled, U-Boot scans 'cpu' node in device tree and calculates CPU number. This does not scale well as changing CPU number also requires modifying .dts and re-compiling U-Boot. This patch uses fw_cfg interface provided by QEMU to detect online CPU number at runtime, and dynamically adds 'cpu' device to U-Boot's driver model.

x86: use actual CPU number for allocating memory

2016-01-13T04:20:15Z

Use actual CPU number, instead of maximum cpu configured, to allocate stack memory in 'load_sipi_vector' Signed-off-by: Miao Yan Reviewed-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng

x86: fix a typo in function name

2016-01-13T04:20:15Z

Rename 'find_cpu_by_apid_id' to 'find_cpu_by_apic_id'. This should be a typo. Signed-off-by: Miao Yan Reviewed-by: Simon Glass Reviewed-by: Bin Meng

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

Some files use global_data but don't declare it. Fix this. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

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
