sh: Isolate uncached mapping support.

2010-02-12T06:40:00Z

This splits out the uncached mapping support under its own config option, presently only used by 29-bit mode and 32-bit + PMB. This will make it possible to optionally add an uncached mapping on sh64 as well as booting without an uncached mapping for 32-bit. Signed-off-by: Paul Mundt

sh: Track the uncached mapping size.

2010-01-21T06:54:31Z

This provides a variable for tracking the uncached mapping size, and uses it for pretty printing the uncached lowmem range. Beyond this, we'll also be building on top of this for figuring out from where the remainder of P2 becomes usable when constructing unrelated mappings. Signed-off-by: Paul Mundt

sh: machine_ops based reboot support.

2010-01-20T07:42:52Z

This provides a machine_ops-based reboot interface loosely cloned from x86, and converts the native sh32 and sh64 cases over to it. Necessary both for tying in SMP support and also enabling platforms like SDK7786 to add support for their microcontroller-based power managers. Signed-off-by: Paul Mundt

sh: Don't perform an icbi on a P2 address

2010-01-13T03:59:24Z

The legacy P2 area may not always be mapped (for example when using PMB). So perform an icbi on an address that we know will always be mapped. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt

sh: hw-breakpoints: Add preliminary support for SH-4A UBC.

2009-12-08T06:02:27Z

This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

sh64: Fix up the CONFIG_GENERIC_BUG=n build.

2009-11-12T07:39:47Z

sh64 doesn't use GENERIC_BUG, which presently causes the handle_BUG() code to blow up. Fix up the dependencies and get it all building again. Signed-off-by: Paul Mundt

sh: nmi_debug support.

2009-09-01T08:38:32Z

This implements support for NMI debugging that was shamelessly copied from the avr32 port. A bit of special magic is needed in the interrupt exception path given that the NMI exception handler is stubbed in to the regular exception handling table despite being reported in INTEVT. So we mangle the lookup and kick off an EXPEVT-style exception dispatch from the INTEVT path for exceptions that do_IRQ() has no chance of handling. As a result, we also drop the evt2irq() conversion from the do_IRQ() path and just do it in assembly. Signed-off-by: Paul Mundt
