Hi,
This series add support for (async) FIFO on the transmit path
of the PL011 UART.
- First we add fifo8_peek_buf() to the fifo8 API (patches 1-3),
- Then we massage a bit the pl011 model to ease development
(patches 4-11),
- Finally we add the TX FIFO implementation using a chardev
front-end 'watch' callback.
The last patch is RFC mostly because I don't know what is the
best way to resolve adding a new migratable field without
breaking the migration stream.
Tested with qtest/avocado/TRS test suites:
trs-workspace$ make test
