From e0980dafa329d33bb88edc8a3ef9fab4e070590c Mon Sep 17 00:00:00 2001 From: Paul B Schroeder Date: Wed, 6 Dec 2006 20:37:03 -0800 Subject: [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.
