  "message": "ttyFDC: Implement KGDB IO operations.\n\nImplement KGDB IO operations for MIPS Fast Debug Channel (FDC). This can\nbe enabled via Kconfig, which also allows the channel number to be\nchosen.\n\nThe magic sysrq hack is implemented in the TTY driver, detecting just ^C\nfor the KGDB channel, and ^O followed by a letter for the FDC console\nchannel.\n\nThe KGDB operations are reasonably efficient thanks to the flush\ncallback, with a 4 byte buffer being used in both directions to allow up\nto 4 bytes to be encoded per FDC word. Reading of data for KGDB will\ndiscard any data received on other channels, which clearly isn\u0027t ideal,\nbut given that there is a single FIFO shared between channels we can\u0027t\ndo much better.\n\nSigned-off-by: James Hogan \u003cjames.hogan@imgtec.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nCc: Jiri Slaby \u003cjslaby@suse.cz\u003e\nCc: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nCc: linux-mips@linux-mips.org\nCc: kgdb-bugreport@lists.sourceforge.net\n",
