* ARM: versatile: merge mach code into a single fileRob Herring2015-12-152-274/+0Star
| | | | | | | | | | | | | | | | | With DT-only support now in place and most of the legacy code removed, the separation of core.c and versatile_dt.c makes little sense. The headers in mach include directory also have to move for multi-platform support, but with a single .c file the remaining definitions needed can also be moved into the versatile_dt.c. In the move, the system registers and IB2 registers are converted to run-time mappings and all register accesses converted to use readl/writel.

* ARM: versatile: switch to DT only booting and remove legacy codeRob Herring2015-12-154-330/+0Star
| | | | | | | | | | | | | | | | With DT support for clocks, irqchips, timers, and PCI now in place, DT based booting has feature parity with non-DT legacy boot. The final piece is actually enabling common clock support on Versatile. Enabling full DT support requires either removing the old Versatile clock code, updating the legacy boot to use the common clock code, or making DT and legacy boot mutually exclusive. Given that removing legacy boot code is the goal anyway, I am going with the 1st option.

* ARM: drop <mach/timex.h> for !ARCH_MULTIPLATFORM, tooUwe Kleine-König2013-12-201-23/+0Star
| | | | | | | | | | | | While <mach/timex.h> isn't used for multi-platform builds since long it still is for "normal" builds. As the previous patches fix all sites to not make use of this per-platform file, it can go now for good also for platforms that are not (yet) converted to multi-platform. While at it there are no users of CLOCK_TICK_RATE any more, so also drop the dummy #define. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

(2) The code was confused between the PCI I/O window (at 0x43000000) and the first PCI memory window (at 0x44000000), which meant that PCI devices using PCI PIO rather than MMIO didn't work. This is fixed (and some variables/labels are renamed to avoid further confusion in future). (3) The SMAP register offsets were all off-by-four, though by fluke this didn't actually have any ill effects. All these changes have been tested on real hardware (PB926 plus the PCI backplane), as well as on QEMU. I have confirmed that IRQs and PCI PIO and MMIO work OK. PCI bus-master DMA doesn't seem to work on h/w -- as far as I can tell the device is correctly managing to DMA to the right places in memory, but every other 32 bit word is corrupt (at least judging from rtl8139 debug dumps of the frames it's receiving). I'm not sure what's going on here, but since this is disjoint from the irq and I/O issues I don't think that applying the patches that fix those should be stalled on trying to debug DMA problems. (DMA works fine on QEMU, incidentally.) * versatile/fixes: ARM: PCI: versatile: Fix SMAP register offsets ARM: PCI: versatile: Fix PCI I/O ARM: PCI: versatile: Fix map_irq function to match hardware Signed-off-by: Olof Johansson <olof@lixom.net>
| * ARM: PCI: versatile: Fix PCI I/OPeter Maydell2013-09-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The versatile PCI controller code was confused between the PCI I/O window (at 0x43000000) and the first PCI memory window (at 0x44000000). Pass the correct base address to pci_remap_io() so that PCI I/O accesses work. Since the first PCI memory window isn't used at all (it's an odd size), rename the associated variables and labels so that it's clear that it isn't related to the I/O window. This has been tested and confirmed to fix PCI I/O accesses both on physical PB926+PCI backplane hardware and on QEMU.

* arm: versatile: fix and enable PCI I/O spaceArnd Bergmann2012-06-172-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit 4d5fc58dbe34b (ARM: remove bunch of now unused mach/io.h files), the I/O space setup was completely broken on versatile. This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.

Before this, it was relative to PAGE_OFFSET and therefore converted to unsigned long as PAGE_OFFSET is an unsigned long. This introduced the following build warning. Fix this by changing the explicit defines of VMALLOC_END to be unsigned long.

* arm: return both physical and virtual addresses from addruartJeremy Kerr2010-10-201-7/+5Star
| | | | | | | | | | | | | | | | | | | | Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in. Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com> and Tony Lindgren <tony@atomide.com>, and fix for versatile express from Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.

* ARM: do not define VMALLOC_END relative to PAGE_OFFSETNicolas Pitre2010-10-021-1/+1
| | | | | | | | | | | VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may vary depending on the selected user:kernel memory split mode through CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to accommodate more directly addressed RAM by the kernel below the vmalloc area, and having VMALLOC_END move along PAGE_OFFSET is rather against the very reason why PAGE_OFFSET can be moved in the first place.

NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files.

* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+1
| | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-291-20/+0Star
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.
