Samuel Holland	e3e5686ef9	lib: sbi_irqchip: Register devices during cold init ... Have the SBI irqchip core keep track of registered irqchip devices. This is useful for any callbacks the irqchip driver may have, such as for warm initialization, the external interrupt handler function, and any future support for handling external interrupts (beyond IPIs) in M-mode. This improves on the tracking done in fdt_irqchip.c, as it tracks device instances, not just drivers, so callbacks can target a specific device.

Anup Patel	d84e7eb7f0	lib: sbi: Remove regs paramter of sbi_irqchip_process() ... The irqchip handlers will typically not need pointer to trap registers so remove regs parameter of sbi_irqchip_process().

Anup Patel	f3f4604c19	lib: sbi: Add a simple external interrupt handling framework ... Currently, the external interrupt handling is scattered between sbi_init and sbi_trap. This patch moves all external interrupt handling into a simple framework called sbi_irqchip.
