2017-04-05board_f: x86: Use checkcpu() for CPU initSimon Glass
At present we misuse print_cpuinfo() do so CPU init on x86. This is done because it is the next available call after the console is enabled. But several arches use checkcpu() instead. Despite the horrible name (which we can fix), it seems a better choice. Adjust the various x86 CPU implementations to move their init code into checkcpu() and use print_cpuinfo() only for printing CPU info.

2016-05-23x86: qemu: move x86 specific operations out of qfw coreMiao Yan
The original implementation of qfw includes several x86 specific operations, like directly calling outb/inb and using some inline assembly code which prevents it being ported to other architectures.

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.

2016-01-24dm: x86: Set up interrupt routing from interrupt_init()Simon Glass
At present interrupt routing is set up from arch_misc_init(). We can do it a little later instead, in interrupt_init(). This removes the manual pirq_init() call. Where the platform does not have an interrupt router defined in its device tree, no error is generated. Some platforms do not have this. Drop pirq_init() since it is no-longer used.
