From 85836c2215498ff18746b3a7e85ed684cf2e119e Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Wed, 9 Jul 2014 20:26:25 +1000 Subject: superio: Use 'pnp_devfn_t' over 'device_t' in romstage component The romstage component of Super I/O support is in fact written around passing a lower and upper half packed integer. We currently have two typedef's for this, 'device_t' and 'pnp_devfn_t'. We wish to make use of 'pnp_devfn_t' over 'device_t' as 'device_t' changes it's typedef in the ramstage context and so is really a conflicting definition. This helps solve problems down the road to having the 'real' 'device_t' definition usable in romstage later. This follows on from the rational given in: c2956e7 device/pci_early.c: Mixes up variants of a typedefs to 'u32' Change-Id: Ia9f238ebb944f9fe7b274621ee0c09a6de288a76 Signed-off-by: Edward O'Callaghan Reviewed-on: http://review.coreboot.org/6231 Reviewed-by: Nico Huber Tested-by: build bot (Jenkins) --- src/superio/serverengines/pilot/early_init.c | 2 +- src/superio/serverengines/pilot/early_serial.c | 8 ++++---- src/superio/serverengines/pilot/pilot.h | 10 +++++----- 3 files changed, 10 insertions(+), 10 deletions(-) (limited to 'src/superio/serverengines/pilot') diff --git a/src/superio/serverengines/pilot/early_init.c b/src/superio/serverengines/pilot/early_init.c index 002210f97b..66356452e5 100644 --- a/src/superio/serverengines/pilot/early_init.c +++ b/src/superio/serverengines/pilot/early_init.c @@ -32,7 +32,7 @@ * Logical device 4, 5 and 7 are being deactivated.
