* ARM: 7389/2: plat-versatile: modernize FPGA IRQ controllerLinus Walleij2012-05-041-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This does two things to the FPGA IRQ controller in the versatile family: - Convert to MULTI_IRQ_HANDLER so we can drop the entry macro from the Integrator. The C IRQ handler was inspired from arch/arm/common/vic.c, recent bug discovered in this handler was accounted for. - Convert to using IRQ domains so we can get rid of the NO_IRQ mess and proceed with device tree and such stuff. As part of the exercise, bump all the low IRQ numbers on the Integrator PIC to start from 1 rather than 0, since IRQ 0 is now NO_IRQ. The Linux IRQ numbers are thus entirely decoupled from the hardware IRQ numbers in this controller. I was unable to split this patch. The main reason is the half-done conversion to device tree in Versatile. Tested on Integrator/AP and Integrator/CP.

Also delete the senseless comment that the file shouldn't be edited, I just edited it and the world didn't come to an end, so it's obviously false. If anyone still has the mentioned ".s file" and the s2h awk script generating that header, raise your hand (and give me your files).

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes introduced in commit cc22b4c18540e5e8bf55c7d124044f9317527d3c "ARM: set vga memory base at run-time" Makes the Integrator/AP freeze completely. I appears that this is due to the VGA base address being assigned at PCI init time, while this base is needed earlier than that. Moving the initialization of the base address to the .map_io function solves this problem.

|/ | | | | | | | | | | | | I was intrigued by the fact that the clock stood still on the Integrator, but it wasn't strange at all, because the timer was set up all wrong and probably has been for a while. With this patch the clock starts ticking again: make the timer periodic (reload), |= on the divisor bit and load the timer before starting it.

The empty set_vpp function in board-at572d940hf_ek.c is left untouched, as the board/SoC is scheduled for removal.

* | [PATCH] fix missing includesTim Schmielau2005-10-301-0/+1
|/ | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
