xtensa: remap io area defined in device tree

2014-01-14T20:25:14+00:00

Use the simple-bus node to discover the io area, and remap the cached and
bypass io ranges. The parent-bus-address value of the first triplet in the
"ranges" property is used. This value is rounded down to the nearest 256MB
boundary. The length of the io area is fixed at 256MB; the "ranges" property
length value is ignored.

Other limitations: (1) only the first simple-bus node is considered, and (2)
only the first triplet of the "ranges" property is considered.

See ePAPR 1.1 §6.5 for the simple-bus node description, and §2.3.8 for the
"ranges" property description.

Piet Delaney, Marc Gauthier, Joe Taylor, Christian Zankel (and possibly
other Tensilica folks).

xtensa: call check_s32c1i after trap_init

Otherwise exceptions may occur prior to exception handling mechanism
initialization, resulting in silently dead system.

of: remove early_init_dt_setup_initrd_arch

All arches do essentially the same thing now for
early_init_dt_setup_initrd_arch, so it can now be removed.
