2016-05-01vme: add vme_init_bridge for common bridge initAaron Sierra
Consolidate vme_bridge structure setup that every bridge was required to do itself. This came about because .irq_mtx is only used within the VME core, but was required to be setup externally. This returns the structure passed in to support shorthand like this: bridge = vme_init_bridge(&priv->bridge); Signed-off-by: Aaron Sierra <asierra@xes-inc.com> Acked-by: Martyn Welch <martyn@welchs.me.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-10-04vme: change bus error handling schemeDmitry Kalinkin
The current VME bus error handler adds errors to the bridge error list. vme_master_{read,write} then traverses that list to look for relevant errors. Such scheme didn't work well for accesses going through vme_master_mmap because they would also allocate a vme_bus_error, but have no way to do vme_clear_errors call to free that memory. This changes the error handling process to be other way around: now vme_master_{read,write} defines a window in VME address space that will catch possible errors. VME bus error interrupt only traverses these windows and marks those that had errors in them.

2015-10-04vme: move tsi148 error handling into VME subsystemDmitry Kalinkin
Error handling code found in tsi148 is not device specific. In fact it already relies on shared vme_bus_error struct and vme_bridge.vme_errors field. The other bridge driver could reuse this code if it is shared. This introduces a slight behavior change: vme error message won't be triggered in a rare case when err_chk=1 and kmalloc fails.

2015-10-04vme: lower alignment requirement in pci bridge driversDmitry Kalinkin
Universe II allows PCI address grannularity of 4K or 64K depending on the window id. tsi148 only supports 64K. Existing driver implementations are validating window size against this grannularity and then use that very size as alignment parameter to pci_bus_alloc_resource. This constraint is excessive, alignment by granularity should be enough. This changes alignment constraint from size to a fixed constraint of 64K.

2014-04-16vme_tsi148: Fix PCI address mapping assumptionJoe Schultz
Previously, tsi148_master_set() assumed the address contained in its PCI bus resource represented the actual PCI bus address. This is a fine assumption on some platforms. However, on platforms that don't use a 1:1 (CPU:PCI) mapping this results in the tsi148 driver configuring an invalid master window translation. This patch updates the vme_tsi148 driver to first convert the address contained in the PCI bus resource into a PCI bus address before using it.

2014-02-15VME: Stop using memcpy_[to|from]io() due to unwanted behaviourMartyn Welch
The ca91cx42 and tsi148 VME bridges use the width of reads and writes on the PCI bus in part to control the width of the cycles on the VME bus. It is important that we can control the width of cycles on the VME bus as some VME hardware requires cycles of a specific width. The memcpy_toio() and memcpy_fromio() functions do not provide sufficient control, so instead loop using ioread functions.

2014-02-07VME: Correct read/write alignment algorithmMartyn Welch
In order to ensure the correct width cycles on the VME bus, the VME bridge drivers implement an algorithm to utilise the largest possible width reads and writes whilst maintaining natural alignment constraints. The algorithm currently looks at the start address rather than the current read/write address when determining whether a 16-bit width cycle is required to get to 32-bit alignment.

2013-12-17vme: Convert VME core to register as a subsystemAaron Sierra
Previously, VME bridge support was treated as any other driver (using module_init() macro), but if VME bridge and vme_user (staging) drivers were compiled into the kernel, then vme_user would attempt to register itself before the VME core support had been loaded. This would result in a kernel panic. The load order of these built-in drivers is based on the order in which drivers/staging/vme and driver/vme are compiled. This patch changes the VME core driver to use the subsys_initcall() macro which ensures that it is loaded before all other VME drivers regardless of the order in which they are compiled.

2013-12-03VME: Provide access to VME bus enumeration and fix vme_user match functionMartyn Welch
The match function for vme_user is completely wrong. It will blindly bind against the first VME slot on each bus (at this point that would be just the first bus as the driver can only handle one bus). The original intention (before some major subsystem changes) was that the driver bind against the slot to which the bridge was attached in the VME system and to the bus(es) provided via the "bus" module parameter. To do this cleanly (i.e. without poking arround in the subsystems internal stuctures) a functionality has been added to provide access to the bus enumeration.

2013-06-17vme: tsi148: Window reserved for accessing CR/CSR does not need attributes setMartyn Welch
The tsi148 driver can be configured to reserve a window for internal use (as part of the error checking routine). The intialisation of this window currently configures a set of attributes that are never used as these are only ever used by the VME core and this window is not advertised to the core. Remove configuration of these attributes. Signed-off-by: Martyn Welch <martyn.welch@ge.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-06-17vme: tsi148: Only store VME bus errors if they will be checkedMartyn Welch
The TSI148 driver provides an optional mechanism for ensuring that errors resulting from posted transfers are caught whilst still relevant. To do this errors are stored in a link list. If bus errors are not checked, this list would grow until available memory had been exhausted. Only store the errors in a link list if error detection is switched on.

2012-07-19VME: Prevent D16 cycles being split into 8-bit blocksMartyn Welch
The memcpy_fromio() and memcpy_toio() functions use the __memcpy() function, at least on x86. This function carries out transfers smaller than 32 bits as multiple 8 bit transfers, causing a single (aligned) 16 bit transfer to be split into 2 8 bit transfers which may not be supported by the target VME device. The commit 53059aa05988761a738fa8bc082bbf3c5d4462d1 fixed this for the ca91cx42, however this was not fixed for the tsi148 at the time. This patch uses the same algorithm to fix the tsi148.
