2009-04-16sh: export board_pci_channels in one placeMagnus Damm8-8/+2
Instead of sometimes exporting board_pci_channels[] in the board specific code just export it in one place. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: pci io port base address codeMagnus Damm1-1/+0
Adds a __get_pci_io_base() function which is used to match a port range against struct pci_channel. This allows us to detect if a port range is assigned to pci or happens to be legacy port io. While at it, remove unused cpu-specific cruft. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: pci memory range checking codeMagnus Damm1-3/+2
This patch changes the code to use __is_pci_memory() instead of is_pci_memaddr(). __is_pci_memory() loops through all the pci channels on the system to match memory windows. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: add io_base member to pci_channelMagnus Damm2-4/+6

2009-04-16sh: add reg_base member to pci_channelMagnus Damm6-6/+8
Store the base address of the pci host controller registers in struct pci_channel and use the address in pci_read_reg() and pci_write_reg(). Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: hook in struct pci_channel in sysdataMagnus Damm2-5/+8
Store a struct pci_channel pointer in bus->sysdata. This makes whatever struct pci_channel assigned to a bus available for sh4_pci_read() and sh4_pci_write(). We also modify PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to use bus->sysdata - this to gives us support for multiple pci channels.

2009-04-16sh: avoid using PCIBIOS_MIN_xxxMagnus Damm6-20/+19
Replaces PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM with direct struct pci_channel access. This allows us to have more than one pci channel. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: add init member to pci_channel dataMagnus Damm18-36/+54
This patch adds an init callback to struct pci_channel and makes sure it is initialized properly. Code is added to call this init function from pcibios_init(). Return values are adjusted and a warning is is printed if init fails. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: pass along struct pci_channelMagnus Damm19-149/+164
These patches rework the pci code for the sh architecture. Currently each board implements some kind of ioport to address mapping. Some boards use generic_io_base others try passing addresses as io ports. This is the first set of patches that try to unify the pci code as much as possible to avoid duplicated code. This will in the end lead to fewer lines board specific code and more generic code. This patch makes sure a struct pci_channel pointer is passed along to various pci functions such as pci_read_reg(), pci_write_reg(), pci_fixup_pcic(), sh7751_pcic_init() and sh7780_pcic_init().

2009-04-04sh: sh7785lcr: Map whole PCI address space.Takashi Yoshii2-17/+8
PCI still doesn't work on sh7785lcr 29bit 256M map mode. On SH7785, PCI -> SHwy address translation is not base+offset but somewhat like base|offset (See HW Manual (rej09b0261) Fig. 13.11). So, you can't export CS2,3,4,5 by 256M at CS2 (results CS0,1,2,3 exported, I guess). There are two candidates. a) 128M@CS2 + 128M@CS4 b) 512M@CS0 Attached patch is B. It maps 512M Byte at 0 independently of memory size. It results CS0 to CS6 and perhaps some more being accessible from PCI. Tested on 7785lcr 29bit 128M map 7785lcr 29bit 256M map (NOT tested on 32bit) Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-03-17sh: dma: Make PVR2 DMA configurable.Paul Mundt2-1/+15
With arch/sh/drivers/dma/ always being built, the Dreamcast DMA engines are being unconditionally built in, regardless of whether the DMA API is enabled or not. This is a regression from previous behaviour, but there is not much advantage in building them all in unconditionally regardless. Add a new config option to make it optional, and update the only user of it to reflect that. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-07-21sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen1-4/+11
This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype.

2008-06-27PCI: remove unused arch pcibios_update_resource() functionsAdrian Bunk1-32/+0
Russell King did the following back in 2003: <-- snip --> [PCI] pci-9: Kill per-architecture pcibios_update_resource() Kill pcibios_update_resource(), replacing it with pci_update_resource(). pci_update_resource() uses pcibios_resource_to_bus() to convert a resource to a device BAR - the transformation should be exactly the same as the transformation used for the PCI bridges. pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to set the high 32-bits to anything non-zero - currently no architecture attempts to do something different. If anyone cares, please fix; I'm going to reflect current behaviour for the time being. Ivan pointed out the following architectures need to examine their pcibios_update_resource() implementation - they should make sure that this new implementation does the right thing. #warning's have been added where appropriate. ia64 mips mips64 This cset also includes a fix for the problem reported by AKPM where 64-bit arch compilers complain about the resource mask being placed in a u32. <-- snip --> This patch removes the unused pcibios_update_resource() functions the kernel gained since, from FRV, m68k, mips & sh architectures.

2008-04-29iomap: fix 64 bits resources on 32 bitsBenjamin Herrenschmidt1-2/+2
Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources.

2008-04-20PCI: remove initial bios sort of PCI devices on x86Greg Kroah-Hartman1-2/+0
We currently keep 2 lists of PCI devices in the system, one in the driver core, and one all on its own. This second list is sorted at boot time, in "BIOS" order, to try to remain compatible with older kernels (2.2 and earlier days). There was also a "nosort" option to turn this sorting off, to remain compatible with even older kernel versions, but that just ends up being what we have been doing from 2.5 days... Unfortunately, the second list of devices is not really ever used to determine the probing order of PCI devices or drivers[1]. That is done using the driver core list instead. This change happened back in the early 2.5 days. Relying on BIOS ording for the binding of drivers to specific device names is problematic for many reasons, and userspace tools like udev exist to properly name devices in a persistant manner if that is needed, no reliance on the BIOS is needed. Matt Domsch and others at Dell noticed this back in 2006, and added a boot option to sort the PCI device lists (both of them) in a breadth-first manner to help remain compatible with the 2.4 order, if needed for any reason. This option is not going away, as some systems rely on them. This patch removes the sorting of the internal PCI device list in "BIOS" mode, as it's not needed at all anymore, and hasn't for many years. I've also removed the PCI flags for this from some other arches that for some reason defined them, but never used them. This should not change the ordering of any drivers or device probing. [1] The old-style pci_get_device and pci_find_device() still used this sorting order, but there are very few drivers that use these functions, as they are deprecated for use in this manner. If for some reason, a driver rely on the order and uses these functions, the breadth-first boot option will resolve any problem.

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y).

2008-01-28sh: update r7780rp interrupt codeMagnus Damm1-14/+2
This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access.
