[POWERPC] Fix new interrupt code (MPIC detection)

2006-07-28T00:53:16Z

As the code comment already says, the Maple device-tree is incorrect here; make the Linux code detect the correct thing, too. Signed-off-by: Segher Boessenkool Acked-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Fix new interrupt code (MPIC endianness)

2006-07-28T00:53:14Z

All U3/U4 based systems are big-endian, not all express it in their device trees. Signed-off-by: Segher Boessenkool Acked-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Add new interrupt mapping core and change platforms to use it

2006-07-03T11:36:01Z

This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Fix booting on Momentum "Apache" board (a Maple derivative)

2006-07-03T07:22:05Z

This extends the maple device-tree workarounds to work on the Apache board as well, and extends the maple platform probing code to recognize the Apache board. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] powerpc: Initialise ppc_md htab pointers earlier

2006-06-28T01:59:47Z

Initialise the ppc_md htab callbacks earlier, in the probe routines. This allows us to call htab_finish_init() from htab_initialize(), and makes it private to hash_utils_64.c. Move htab_finish_init() and make_bl() above htab_initialize() to avoid forward declarations. Signed-off-by: Michael Ellerman Signed-off-by: Paul Mackerras

[PATCH] powerpc: Don't print chosen idle loop at every boot

2006-04-22T08:45:11Z

No need to write out what idle loop is used on every boot. Signed-off-by: Olof Johansson Signed-off-by: Paul Mackerras

[PATCH] powerpc: Kill _machine and hard-coded platform numbers

2006-03-28T12:15:54Z

This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

powerpc: Unify the 32 and 64 bit idle loops

2006-03-27T04:03:03Z

This unifies the 32-bit (ARCH=ppc and ARCH=powerpc) and 64-bit idle loops. It brings over the concept of having a ppc_md.power_save function from 32-bit to ARCH=powerpc, which lets us get rid of native_idle(). With this we will also be able to simplify the idle handling for pSeries and cell. Signed-off-by: Paul Mackerras

[PATCH] powerpc: Fix Maple build

2006-01-15T02:14:47Z

The changes to the device node structure broke Maple build. This fixes it. Unfortunately I coudn't test as my Maple board appears to be dead. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras
