Righty ho. This seems to be a reasonable attempt.
https://github.com/rickytarr/linux/tree/subsys-mailbox
https://github.com/rickytarr/linux/commit/e0c25371581d125e3f6a46f452ce3e95f1d267ee
It compiles cleanly and boots. Start with bcm2835_defconfig, and then
enable Device Drivers -> Mailbox Hardware Support -> BCM 2835 Mailbox. I
think it validates that BCM2835 mailbox support can fit into your
generic device.
But that's as far as I know. I'm offering this as an early look only
(comments and defects welcome). I've got to build something that uses it
next. For all I know it might cause the Raspberry Pi to explode and
vaporise any desk it is sitting on.
Out of interest, do you have a roadmap for moving this into the kernel
mainline?
Cheers,
Craig.
