| * sh: Make initrd detection more robust.Paul Mundt2010-05-06
| | | | | | | | | | | | | | | | | | | | Various boot loaders go to various extents to thwart the initrd detection logic (mostly on account of not being able to be bothered with adhering to the established boot ABI), so we make the detection logic a bit more robust. This makes it possible to work around the SDK7786's firmware's attempts to thwart compressed image booting. Victory is mine. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This wires up CPU hotplug for SH-X3 SMP CPUs. Presently only secondary cores can be hotplugged given that the boot CPU has to contend with the broadcast timer. When real local timers are implemented this restriction can be lifted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for hardware-managed IRQ balancing as implemented by SH-X3 cores (presently only hooked up for SH7786, but can probably be carried over to other SH-X3 cores, too). CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask.
