sh: wire up perf alignment and emulation faults.

This plugs in the alignment and emulation fault reporting for perf sw events. Signed-off-by: Paul Mundt

sh: boot kernel with SR.BL set

2010-09-30T00:43:32Z

Update the SH kernel to keep SR.BL set until the VBR register has been initialized. Useful to allow boot of the kernel even though exceptions are pending. Without this patch there is a window of time when exceptions such as NMI are enabled but no exception handlers are installed. This patch modifies both the zImage loader and the actual kernel to boot with BL=1, but the zImage loader is modfied in such a way that the init_sr value is unchanged to not break the zImage loader provided by kexec. Tested on sh7724 Ecovec and on the SH4AL-DSP core included in sh7372. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: Setup boot CPU VBR early to enable early page faults.

2010-02-17T03:33:22Z

vmemmap and the vmsplit code amongst others need to be able to take page faults much earlier than trap_init() time, so move this in to the early CPU initialization. VBR setup for secondary CPUs is already handled through start_secondary(), so we only need to do this for the boot CPU. Signed-off-by: Paul Mundt

sh: Split out the unaligned counters and user bits.

2010-01-12T07:12:25Z

This splits out the unaligned access counters and userspace bits in to their own generic interface, which will allow them to be wired up on sh64 too. Signed-off-by: Paul Mundt

sh: Tidy up the sh bios VBR handling.

2010-01-12T05:50:43Z

This moves the VBR handling out of the main trap handling code and in to the sh-bios helper code. A couple of accessors are added in order to permit other kernel code to get at the VBR value for state save/restore paths. Signed-off-by: Paul Mundt

sh: Fix up breakpoint trap handler patching on SH-2A.

2010-01-05T03:44:02Z

SH-2A was referencing the old handler that no longer exists, fix it up. Signed-off-by: Paul Mundt

sh: Make the unaligned trap handler always obey notification levels.

2009-12-14T02:46:09Z

Presently there are a couple of paths in to the alignment handler, where only the address error path presently quiets the notificiation messages based on the configuration settings. We carry over the notification level tests to the default alignment handler itself incase so that they behave uniformly. Signed-off-by: Paul Mundt

sh: Disable SCIF2 on the SH-X3 proto CPU.

2009-10-18T06:13:28Z

SCIF2 and the FPU exceptions happen to share vector numbers, one in EXPEVT and the other in INTEVT. This is a violation of the interface and should have never made it in to silicon. On top of that, the demux hack that was added for special dispatch is rather error prone, and introduces more problems than it solves. Kill all of it off, and just refuse to deal with SCIF2 outright.
