2011-04-20powerpc/nvram: Search for nvram using compatibleBenjamin Herrenschmidt1-0/+2
As well as searching for nodes with type = "nvram", search for nodes that have compatible = "nvram". This can't be converted into a single call to of_find_compatible_node() with a non-NULL type, because that searches for a node that has _both_ type & compatible = "nvram".

2011-04-20powerpc/xics: Move irq_host matching into the ics backendMichael Ellerman2-5/+18
An upcoming new ics backend will need to implement different matching semantics to the current ones, which are essentially the RTAS ics backends. So move the current match into the RTAS backend, and allow other ics backends to override.

2011-04-20powerpc: Add SCOM infrastructureBenjamin Herrenschmidt3-0/+201
SCOM is a side-band configuration bus implemented on some processors. This code provides a way for code to map and operate on devices via SCOM, while the details of how that is implemented is left up to a SCOM "controller" in the platform code.

2011-04-20powerpc/xics: Make sure we have a sensible default distribution serverBenjamin Herrenschmidt1-3/+9
Even when nothing is specified in the device tree, and despite the fact that we don't setup links properly yet, we still need a reasonable value in there or some interrupts won't be setup properly to point to an existing processor. Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-04-20powerpc/xics: Rewrite XICS driverBenjamin Herrenschmidt8-0/+1211
This is a significant rework of the XICS driver, too significant to conveniently break it up into a series of smaller patches to be honest. The driver is moved to a more generic location to allow new platforms to use it, and is broken up into separate ICP and ICS "backends". For now we have the native and "hypervisor" ICP backends and one common RTAS ICS backend. The driver supports one ICP backend instanciation, and many ICS ones, in order to accomodate future platforms with multiple possibly different interrupt "sources" mechanisms.

Fix a possible problem with mport registration left non-cleared after fsl_rio_setup() exits on link error. Abort mport initialization if registration failed. This patch is applicable to 2.6.39-rc1 only. The problem does not exist for earlier versions.

The new core code allows to update the type in irq_data and return IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for setting the IRQ_LEVEL flag.

The following code snippet: unsigned int cpu = 0; if (mpic->flags & MPIC_PRIMARY) cpu = hard_smp_processor_id(); is seen in several places in the 'mpic.c' code.

2011-03-21powerpc: Make MPIC honor the "pic-no-reset" device tree propertyMeador Inge1-11/+55
This property, defined in the Open PIC binding, tells the kernel not to use the reset bit in the global configuration register. Additionally, its presence mandates that only sources which are actually used (i.e. appear in the device tree) should have their VECPRI bits initialized. Although, "pic-no-reset" can be used for the same use cases that "protected-sources" is covering, the "protected-sources" implementation was left completely intact. This is a more pragmatic approach as there are already several existing systems which use protected sources. If "pic-no-reset" *and* "protected-sources" are both used, however, then "pic-no-reset" takes precedence in terms of the init behavior and the sanity checks done by protected sources will still take place.
