* ARM: convert PCI defines to variablesRob Herring2011-07-121-0/+3
| | | | | | | | | | | | | | Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow multi-platform builds. This also removes the requirement for a platform to have a mach/hardware.h. The default values for i/o and mem are 0x1000 and 0x01000000, respectively. Per Arnd Bergmann, other values are likely to be incorrect, but this commit does not try to address that issue.

| | | | | | | | | | | | This updates the IOP platform to use the kernel's generic time framework.

* iop: clockevent supportMikael Pettersson2009-10-291-11/+90
| | | | | | | | | | | | | | | | | | | | | | | This updates the IOP platform to expose the interrupting timer 0 as a clockevent object. The timer interrupt handler is changed to call the clockevent ->event_handler() instead of timer_tick(), and ->set_next_event() and ->set_mode() operations are added to allow the mode of the timer to be updated (required for ONESHOT/NOHZ mode). Timer 0 must now be properly initialised, which requires a new write_tcr0() function from the mach-specific code. The mode of timer 0 must be read at the start of ->set_mode(), which requires a new read_tmr0() function from the mach- specific code. Initial setup of timer 0 is also rewritten to be more robust.

On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1.

Change the name of the operation to 'val' (for 'validate'). This is in anticipation of the p+q case where it is a requirement to identify the target parity buffers separately from the source buffers, because the target parity buffers will not have corresponding pq coefficients.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

Linux should handle this initialization for three reasons: 1/ The memory map that RedBoot sets up is not optimal (page_to_dma and virt_to_phys return different addresses). The effect of this is that using the dma mapping API for the internal bus dma units generates pci bus addresses that are incorrect for the internal bus. 2/ Not all iop platforms use RedBoot 3/ If the ATU is already initialized it indicates that the iop is an add-in card in another host, it does not own the PCI bus, and should not be re-initialized.
