2017-06-03drivers/misc: add Aspeed LPC snoop driverRobert Lippert1-0/+261
This driver enables the LPC snoop hardware on the ASPEED BMC which generates an interrupt upon every write to an I/O port by the host. This is typically used to monitor BIOS boot progress by listening to well-known debug port 80h. The functionality in this commit just saves all snooped values to a circular 2K buffer in the kernel, subsequent commits can act on the values to do things with them.
