x86: qemu: split qfw command interface and qfw core

2016-05-23T07:18:00Z

This patch splits qfw command interface and qfw core function into two files, and introduces a new Kconfig option (CONFIG_QFW) for qfw core. Now when qfw command interface is enabled, it will automatically select qfw core. This patch also makes the ACPI table generation select CONFIG_QFW. Signed-off-by: Miao Yan Reviewed-by: Bin Meng

x86: qemu: Move qfw command over to cmd and add Kconfig entry

2016-05-23T07:18:00Z

- Move the command portion of arch/x86/cpu/qemu/fw_cfg.c into cmd/qemu_fw_cfg.c - Move arch/x86/include/asm/fw_cfg.h to include/qemu_fw_cfg.h - Rename ACPI table portion to arch/x86/cpu/qemu/acpi_table.c Signed-off-by: Tom Rini Reviewed-by: Bin Meng

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.
