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.

2016-01-13x86: qemu: add fw_cfg supportMiao Yan
The QEMU fw_cfg interface allows the guest to retrieve various data information from QEMU. For example, APCI/SMBios tables, number of online cpus, kernel data and command line, etc. This patch adds support for QEMU fw_cfg interface.
