[PATCH] Exar quad port serial
This is on our "Envoy" boxes which we have, according to the documentation, an
"Exar ST16C554/554D Quad UART with 16-byte Fifo's". The box also has two
other "on-board" serial ports and a modem chip.
The two on-board serial UARTs were being detected along with the first two
Exar UARTs. The last two Exar UARTs were not showing up and neither was the
modem.
This patch was the only way I could the kernel to see beyond the standard four
serial ports and get all four of the Exar UARTs to show up.
