Stephen Rothwell	d86d9b8cab	[POWERPC] fix spin lock nesting in hvc_iseries ... We had nested spinlocks using the same flags variable, but it turns out that we don't need the nested locks at all (the lock protects a static buffer that we aren't using here), so just remove the extra locks.

Stephen Rothwell	4e9e95a355	[POWERPC] Make the hvc_console output buffer size settable ... So the iSeries console will be faster since it can send up to 200 bytes at a time to the Hypervisor. This only affects the tty part of the console, the console writes are still in 16 byte lots. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>	2006-07-13 18:53:32 +10:00
Stephen Rothwell	8bff05b052	[POWERPC] iseries: A new iSeries console ... This driver uses the hvc_console.c infrastructure that is used by the pSeries virtual and RTAS consoles. This will allow us to make viocons.c obsolete and is another step along the way to a combined kernel (as viocons could not coexist with CONFIG_VT).
