From 1790cf9111f61d360d861901b97eba4de3b5414c Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Thu, 24 Aug 2006 21:32:49 -0400 Subject: [PARISC] Create shared header Pull out struct sba_device and struct lba_device into a common ropes.h header. Also fold the parisc portion of iosapic.h into this file. (Then delete the useless portion of iosapic.h) Signed-off-by: Kyle McMartin --- drivers/parisc/iosapic.c | 2 +- drivers/parisc/lba_pci.c | 40 +---------------- drivers/parisc/sba_iommu.c | 109 +-------------------------------------------- 3 files changed, 3 insertions(+), 148 deletions(-) (limited to 'drivers/parisc') diff --git a/drivers/parisc/iosapic.c b/drivers/parisc/iosapic.c index 90489ade632e..c2949b4367e5 100644 --- a/drivers/parisc/iosapic.c +++ b/drivers/parisc/iosapic.c @@ -146,7 +146,7 @@ #include #endif -#include +#include #include "./iosapic_private.h" #define MODULE_NAME "iosapic" diff --git a/drivers/parisc/lba_pci.c b/drivers/parisc/lba_pci.c index a596dbc804a3..98f03686a710 100644 --- a/drivers/parisc/lba_pci.c +++ b/drivers/parisc/lba_pci.c @@ -46,9 +46,9 @@ #include #include +#include #include /* for register_parisc_driver() stuff */ #include -#include /* for iosapic_register() */ #include /* read/write stuff */ #undef DEBUG_LBA /* general stuff */ @@ -169,44 +169,6 @@ #define LBA_PORT_BASE (PCI_F_EXTEND | 0xfee00000UL) static void __iomem *astro_iop_base __read_mostly; -#define ELROY_HVERS 0x782 -#define MERCURY_HVERS 0x783 -#define QUICKSILVER_HVERS 0x784 - -static inline int IS_ELROY(struct parisc_device *d) -{ - return (d->id.hversion == ELROY_HVERS); -} - -static inline int IS_MERCURY(struct parisc_device *d) -{ - return (d->id.hversion == MERCURY_HVERS); -} - -static inline int IS_QUICKSILVER(struct parisc_device *d) -{ - return (d->id.hversion == QUICKSILVER_HVERS); -} - - -/* -** lba_device: Per instance Elroy data structure -*/ -struct lba_device { - struct pci_hba_data hba; - - spinlock_t lba_lock; - void *iosapic_obj; - -#ifdef CONFIG_64BIT - void __iomem * iop_base; /* PA_VIEW - for IO port accessor funcs */ -#endif - - int flags; /* state/functionality enabled */ - int hw_rev; /* HW revision of chip */ -}; - - static u32 lba_t32; /* lba flags */ diff --git a/drivers/parisc/sba_iommu.c b/drivers/parisc/sba_iommu.c index 5fbc11e4bc5d..12776b7e3a84 100644 --- a/drivers/parisc/sba_iommu.c +++ b/drivers/parisc/sba_iommu.c @@ -38,6 +38,7 @@ #include #include +#include #include /* for proc_mckinley_root */ #include /* for proc_runway_root */ #include /* for PDC_MODEL_* */ @@ -46,11 +47,6 @@ #define MODULE_NAME "SBA" -#ifdef CONFIG_PROC_FS -/* depends on proc fs support.
