* powerpc/fsl-booke: Make CAM entries used for lowmem configurableTrent Piepho2009-01-28
| | | | | | | | | | | | On booke processors, the code that maps low memory only uses up to three CAM entries, even though there are sixteen and nothing else uses them. Make this number configurable in the advanced options menu along with max low memory size. If one wants 1 GB of lowmem, then it's typically necessary to have four CAM entries.

* powerpc/fsl-booke: Allow larger CAM sizes than 256 MBTrent Piepho2009-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code that maps kernel low memory would only use page sizes up to 256 MB. On E500v2 pages up to 4 GB are supported. However, a page must be aligned to a multiple of the page's size. I.e. 256 MB pages must aligned to a 256 MB boundary. This was enforced by a requirement that the physical and virtual addresses of the start of lowmem be aligned to 256 MB. Clearly requiring 1GB or 4GB alignment to allow pages of that size isn't acceptable. To solve this, I simply have adjust_total_lowmem() take alignment into account when it decides what size pages to use. Give it PAGE_OFFSET = 0x7000_0000, PHYSICAL_START = 0x3000_0000, and 2GB of RAM, and it will map pages like this: PA 0x3000_0000 VA 0x7000_0000 Size 256 MB PA 0x4000_0000 VA 0x8000_0000 Size 1 GB PA 0x8000_0000 VA 0xC000_0000 Size 256 MB PA 0x9000_0000 VA 0xD000_0000 Size 256 MB PA 0xA000_0000 VA 0xE000_0000 Size 256 MB Because the lowmem mapping code now takes alignment into account, PHYSICAL_ALIGN can be lowered from 256 MB to 64 MB. Even lower might be possible. The lowmem code will work down to 4 kB but it's possible some of the boot code will fail before then. Poor alignment will force small pages to be used, which combined with the limited number of TLB1 pages available, will result in very little memory getting mapped. So alignments less than 64 MB probably aren't very useful anyway. Signed-off-by: Trent Piepho <tpiepho@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/fsl-booke: Remove code duplication in lowmem mappingTrent Piepho2009-01-28
| | | | | | | | | | | | | | | The code to map lowmem uses three CAM aka TLB[1] entries to cover it. The size of each is stored in three globals named __cam0, __cam1, and __cam2. All the code that uses them is duplicated three times for each of the three variables. We have these things called arrays and loops.... Once converted to use an array, it will be easier to make the number of CAMs configurable. Signed-off-by: Trent Piepho <tpiepho@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/fsl-booke: Cleanup init/exception setup to be runtimeKumar Gala2009-01-28
| | | | | | | | | | | | | | | | | | We currently have a few variants of fsl-booke processors (e500v1, e500v2, e500mc, and e200). They all have minor differences that we had previously been handling via ifdefs. To move towards having this support the following changes have been made: * PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on e500mc or e200. We use MMUCFG[NPIDS] to determine which case we are since we only touch PID1/2 in extremely early init code. * Not all IVORs exist on all the processors so introduce cpu_setup functions for each variant to setup the proper IVORs that are either unique or exist but have some variations between the processors Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/83xx: Add PCI-E support for all MPC83xx boards with PCI-EAnton Vorontsov2009-01-28

* powerpc/fsl_pci: Add MPC83xx PCI-E controller RC mode supportAnton Vorontsov2009-01-28
| | | | | | | | | | | | | | | | This patch adds support for PCI-Express controllers as found on the newer MPC83xx chips. The work is loosely based on the Tony Li's patch[1], but unlike the original patch, this patch implements sliding window for the Type 1 transactions using outbound window translations, so we don't have to ioremap the whole PCI-E configuration space.

| | | | | | | | | | | | | | | | | | | | | | | | _PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set. This will work on normal SMP setups because we force-set CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

| * powerpc/pseries: Correct VIO bus accounting problem in CMO env.Robert Jennings2009-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path.

The test for pending softirq has been removed because it is allready done in irq_exit(). Since system_call() is allso using the SAVE_ALL macro and returning via ret_from_exception label I see no reason why we could not do this here as well. This is also handy because if we return from the timer interrupt and we need to resched than we check for this :) Signed-off-by: Sebastian Siewior <bigeasy@linutronix.de> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
