2009-08-28OMAP2/3: Pass irqflags to 8250 driverVikram Pandita
Pass irqflags to 8250 driver with platform_data. At least Zoom2 has IRQF_TRIGGER_RISING requirement for the 8250 GPIO irq. This patch is dependent on 8250 driver changes getting accepted upstream: http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=7053133124d5cdf207c1168c7a0c582a18e12ea7 Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-08-28OMAP: UART: drop OMAP_TAG_UART, enable all UARTs, auto-disabled on idleKalle Valo
OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

2009-08-28powerpc: Properly start decrementer on BookE secondary CPUsBenjamin Herrenschmidt
This moves the code to start the decrementer on 40x and BookE into a separate function which is now called from time_init() and secondary_time_init(), before the respective clock sources are registered. We also remove the 85xx specific code for doing it from the platform code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-08-28powerpc: derive COMMAND_LINE_SIZE from asm-genericPaul Gortmaker

2009-08-28powerpc/pci: Pull ppc32 PCI features into commonKumar Gala
Some of the PCI features we have in ppc32 we will need on ppc64 platforms in the future. These include support for: * ppc_md.pci_exclude_device * indirect config cycles * early config cycles We also simplified the logic in fake_pci_bus() to assume it will always get a valid pci_controller. Since all current callers seem to pass it one.

2009-08-28powerpc/pci: move pci_64.c device tree scanning code into pci-common.cGrant Likely
The PCI device tree scanning code in pci_64.c is some useful functionality. It allows PCI devices to be described in the device tree instead of being probed for, which in turn allows pci devices to use all of the device tree facilities to describe complex PCI bus architectures like GPIO and IRQ routing (perhaps not a common situation for desktop or server systems, but useful for embedded systems with on-board PCI devices). This patch moves the device tree scanning into pci-common.c so it is available for 32-bit powerpc machines too.

2009-08-28powerpc/book3e-64: Add support to initial_tlb_book3e for non-HES TLBKumar Gala
We now search through TLBnCFG looking for the first array that has IPROT support (we assume that there is only one). If that TLB has hardware entry select (HES) support we use the existing code and with the proper TLB select (the HES code still needs to clean up bolted entries from firmware). The non-HES code is pretty similiar to the 32-bit FSL Book-E code but does make some new assumtions (like that we have tlbilx) and simplifies things down a bit.

2009-08-28powerpc/book3e-64: Add helper function to setup IVORsKumar Gala
Not all 64-bit Book-3E parts will have fixed IVORs so add a function that cpusetup code can call to setup the base IVORs (0..15) to match the fixed offsets. We need to 'or' part of interrupt_base_book3e into the IVORs since on parts that have them the IVPR doesn't extend as far down.

2009-08-28powerpc/book3e-64: Wait til generic_calibrate_decr to enable decrementerKumar Gala
Match what we do on 32-bit Book-E processors and enable the decrementer in generic_calibrate_decr. We need to make sure we disable the decrementer early in boot since we currently use lazy (soft) interrupt on 64-bit Book-E and possible get a decrementer exception before we are ready for it.

2009-08-28powerpc/book3e-64: Move the default cpu table entryKumar Gala

2009-08-28powerpc/mm: Add MMU features for TLB reservation & Paired MAS registersKumar Gala
Support for TLB reservation (or TLB Write Conditional) and Paired MAS registers are optional for a processor implementation so we handle them via MMU feature sections. We currently only used paired MAS registers to access the full RPN + perm bits that are kept in MAS7||MAS3. We assume that if an implementation has hardware page table at this time it also implements in TLB reservations.

2009-08-27x86: Sanitize smp_record and move it to x86_init_opsThomas Gleixner
The x86 quirkification introduced an extra ugly hackery with a variable pointer in the mpparse code. If the pointer is initialized then it is dereferenced and the variable set to 0 or incremented.

2009-08-27x86: Add request_standard_resources to x86_initThomas Gleixner
The 32bit and the 64bit code are slighty different in the reservation of standard resources. Also the upcoming Moorestown support needs its own version of that. Add it to x86_init_ops and initialize it with the 64bit default. 32bit overrides it in early boot. Now moorestown can add it's own override w/o sprinkling the code with more #ifdefs Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-27x86: Add probe_roms to x86_initThomas Gleixner

2009-08-27x86: Add x86_init infrastructureThomas Gleixner
The upcoming Moorestown support brings the embedded world to x86. The setup code of x86 has already a couple of hooks which are either x86_quirks or paravirt ops. Some of those setup hooks are pretty convoluted like the timer setup and the tsc calibration code. But there are other places which could do with a cleanup. Instead of having inline functions/macros which are modified at compile time I decided to introduce x86_init ops which are unconditional in the code and make it clear that they can be changed either during compile time or in the early boot process. The function pointers are initialized by default functions which can be noops so that the pointer can be called unconditionally in the most cases. This also allows us to remove 32bit/64bit, paravirt and other #ifdeffery. paravirt guests are just a hardware platform in the setup code, so we should treat them as such and not hide all behind multiple layers of indirection and compile time dependencies. It's more obvious that x86_init.timers.timer_init() is a function pointer than the late_time_init = choose_time_init() obscurity. It's also way simpler to grep for x86_init.timers.timer_init and find all the places which modify that function pointer instead of analyzing weak functions, macros and paravirt indirections. Note. This is not a general paravirt_ops replacement. It just will move setup related hooks which are potentially useful for other platform setup purposes as well out of the paravirt domain. Add the base infrastructure without any functionality. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
