Subject: RE: [PATCH] 8250/16?50: Add support for Broadcom TruManage
 redirected serial port

From: Stephen Hurd <shurd@...adcom.com>

Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725).

This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts.  The UART_CAP_HFIFO capability was added to track this.  It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).

Patch against linux-2.7 from ftp.kernel.org downloaded Dec-11-2012.

I don't know anybody here off hand who does Linux work nor am I in a position to configure the Exchange server.  If this still isn't acceptable, I guess I could try emailing this patch around internally and hope it lands with someone has the appropriate magic available.
