* iop3xx: ATU and PCI memory configuration correctedAaro Koskinen2009-08-18
| | | | | | | | | | | | | | | | | | | | | | | | There are two 64 MB outbound memory windows at bus addresses 0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI memory. Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. 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. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.

* iop: Program outbound windows using the correct definitionsRussell King2008-03-26
| | | | | | | | | | | | | | The outbound translate registers should be programmed with the bus addresses that are defined in the header files, rather than the physical address. Currently it doesn't matter because they're identical, but the headers currently allow them to be different, and not using the right macros here means that people are in for a surprise if they change them.

* | Detach sched.h from mm.hAlexey Dobriyan2007-05-21
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

* [ARM] 4348/4: iop3xx: Give Linux control over PCI initializationDan Williams2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the iop3xx platform support code assumes that RedBoot is the bootloader and has already initialized the ATU. 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.

* [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static rangesDan Williams2007-02-14
| | | | | | | | | | Implement a custom ioremap implementation for iop3xx. This saves establishing new mappings. It also cleans up the PCI IO resource to be a physical address rather than a virtual address as Russell pointed out on the original iop13xx port.
