From b70ac7718579b5cbf3bdd74fd01132d1c91596f4 Mon Sep 17 00:00:00 2001 From: David Miller Date: Mon, 13 Oct 2008 10:36:31 +0100 Subject: serial: allow 8250 to be used on sparc This requires three changes: 1) Remove !SPARC restriction in Kconfig. 2) Move Sparc specific serial drivers before 8250, so that serial console devices don't change names on us, even if 8250 finds devices. 3) Since the Sparc specific serial drivers try to use the same major/minor device namespace as 8250, some coordination is necessary. Use the sunserial_*() layer routines to allocate minor number space within TTY_MAJOR when CONFIG_SPARC. This has no effect on other platforms. Thanks to Josip Rodin for bringing up this issue and testing plus debugging various revisions of this patch. Signed-off-by: David S.
