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.

2012-04-26Staging: VME: move VME drivers out of stagingGreg Kroah-Hartman
This moves the VME core, VME board drivers, and VME bridge drivers out of the drivers/staging/vme/ area to drivers/vme/. The VME device drivers have not moved out yet due to some API questions they are still working through, that should happen soon, hopefully.
