The new OSLog region in MTP (firmware 13.3+) persists on handoff to
Linux. To avoid having to come up with some weird DART handoff or DAPF
tricks, let's just steal some of the coprocessor's dedicated SRAM. This
keeps it happy and Linux doesn't need any special handoff then.

This will work for u-boot itself, but needs a special workaround in the
MTP driver for Linux handoff to work.

Apple M2 devices have an MTP coprocessor in charge of keyboard/trackpad
handling, communicating over a DockChannel interface. Add a simple
driver for this.
The keyboard does not require any initialization messages, but we have a
problem: we cannot reset the MTP so Linux can start it fresh, and it
delivers a number of informative packets on startup. To work around
this, we buffer those messages and re-inject them into the FIFO (which
is big enough to hold all of them) on shutdown, so Linux finds them when
it initializes its driver. The actual MTP coprocessor is quiesced, which
does work properly.

This driver handles the MTP ASC coprocessor, which does not need any

Commit 68dcbdd594 ("ARM: imx: Add weak default reset_cpu()") caused

Fix it by switching to the watchdog driver model via sysreset, which
