drivers that attach to it. This allows for other host interface chips that use the same keyboards and mice, such as the ones in the ARM IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still called pckbc(4), and the new abstraction layer is "pckbport", so the child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which also contains some code shared between all host controllers. To avoid incompatibility, pckbdreg.h is still installed in /usr/include/dev/pckbc. In theory, this shouldn't cause any behavioural changes in the drivers concerned. Thy just use rather more function pointers than before. Tested on i386 and (with a new host driver) acorn32. Compiled on several other affected architectures.
