Haojian Zhuang June 8, 2013, 2:47 p.m. UTC
Add board support with device tree for Hisilicon Hi36xx/Hi37xx platform.

Changelog:
v3:
1. Remove .map_io() in DT machine descriptor. Since debug_ll_io_init()
is called by default.
2. Remove .init_machine() in DT machine descriptor. Since
of_platform_populate() is called by default in DT mode.

v2:
1. Remove .init_irq() in DT machine descriptor. Since irqchip_init()
is called by default in DT mode.

Having the same namespace for boards and for SoCs is _extremely_ confusing.
I know it's not something you made up, but if you have a chance to influence
future naming, please do so. Or maybe consider using a different naming
scheme than just "hixxxx" for boards in the sources.

Should you list the hisilicon,hi3716-dkb board here too, since you add the
bindings doc for it?

Maybe. But it's still their choice.

If all of these patches are merged, I can submit hi3716-dkb continuously.

The more things what I add only cause me pending more time.
