From ca0c14e447a399eb90a1c9a4357560c2a29ef499 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 17 Dec 2008 11:47:59 +0900 Subject: sh: Kill off sh_bios_in_gdb_mode(). With the reworked kgdb support, we always detach and reinitialize the stub. This was mostly a feature for handoffs between sh-ipl+g and the kgdb stub, but virtually no sh-ipl+g versions ever had this working right in the first place. Given that the sh-ipl+g stubs in general use today don't even support the GDB stub, and we have already killed off the special casing in the sh-sci serial driver, kill off this now unused symbol too.
