From 8369ce4cfe18decc3ea0afcf91e67c665479c78e Mon Sep 17 00:00:00 2001 From: David Howells Date: Sun, 8 Jan 2006 01:01:18 -0800 Subject: [PATCH] [PATCH] frv: drop unsupported debugging features Drop support for debugging features that aren't supported on FRV: (*) EARLY_PRINTK The on-chip UARTs are set up early enough that this isn't required, and VGA support isn't available. There's also a gdbstub available. (*) DEBUG_PAGEALLOC This can't be easily be done since we use huge static mappings to cover the kernel, not pages.
