vme: add vme_init_bridge for common bridge init

2016-05-01T21:00:00Z

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 Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: change bus error handling scheme

2015-10-04T18:50:57Z

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. Signed-off-by: Dmitry Kalinkin Cc: Igor Alekseev Signed-off-by: Greg Kroah-Hartman

vme: move tsi148 error handling into VME subsystem

2015-10-04T18:50:57Z

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.
