From eb867a76238fb38e952c37871b16d0d7fd61c95f Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 20 Feb 2007 09:05:45 +0100 Subject: [PATCH] [PATCH 9_9] Use "void *" not "unsigned long *" for block dev read_write buffer pointers Block device read/write is anonymous data; there is no need to use a typed pointer. void * is fine. Also add a hook for block_read functions Signed-off-by: Grant Likely --- common/cmd_ide.c | 8 ++++---- common/cmd_scsi.c | 4 ++-- common/usb_storage.c | 4 ++-- cpu/pxa/mmc.c | 2 +- drivers/systemace.c | 7 +++---- include/ide.h | 4 ++-- include/part.h | 2 +- 7 files changed, 15 insertions(+), 16 deletions(-) diff --git a/common/cmd_ide.c b/common/cmd_ide.c index ebc080c72a..2e185cc441 100644 --- a/common/cmd_ide.c +++ b/common/cmd_ide.c @@ -188,7 +188,7 @@ static void ident_cpy (unsigned char *dest, unsigned char *src, unsigned int len #ifdef CONFIG_ATAPI static void atapi_inquiry(block_dev_desc_t *dev_desc); -ulong atapi_read (int device, lbaint_t blknr, ulong blkcnt, ulong *buffer); +ulong atapi_read (int device, lbaint_t blknr, ulong blkcnt, void *buffer); #endif @@ -1233,7 +1233,7 @@ static void ide_ident (block_dev_desc_t *dev_desc) /* ------------------------------------------------------------------------- */ -ulong ide_read (int device, lbaint_t blknr, ulong blkcnt, ulong *buffer) +ulong ide_read (int device, lbaint_t blknr, ulong blkcnt, void *buffer) { ulong n = 0; unsigned char c; @@ -1353,7 +1353,7 @@ IDE_READ_E: /* ------------------------------------------------------------------------- */ -ulong ide_write (int device, lbaint_t blknr, ulong blkcnt, ulong *buffer) +ulong ide_write (int device, lbaint_t blknr, ulong blkcnt, void *buffer) { ulong n = 0; unsigned char c; @@ -2015,7 +2015,7 @@ static void atapi_inquiry(block_dev_desc_t * dev_desc) #define ATAPI_READ_BLOCK_SIZE 2048 /* assuming CD part */ #define ATAPI_READ_MAX_BLOCK ATAPI_READ_MAX_BYTES/ATAPI_READ_BLOCK_SIZE /* max blocks */ -ulong atapi_read (int device, lbaint_t blknr, ulong blkcnt, ulong *buffer) +ulong atapi_read (int device, lbaint_t blknr, ulong blkcnt, void *buffer) { ulong n = 0; unsigned char ccb[12]; /* Command descriptor block */ diff --git a/common/cmd_scsi.c b/common/cmd_scsi.c index b17bebbacf..da36ed9e1d 100644 --- a/common/cmd_scsi.c +++ b/common/cmd_scsi.c @@ -74,7 +74,7 @@ void scsi_setup_inquiry(ccb * pccb); void scsi_ident_cpy (unsigned char *dest, unsigned char *src, unsigned int len); -ulong scsi_read(int device, ulong blknr, ulong blkcnt, ulong *buffer); +ulong scsi_read(int device, ulong blknr, ulong blkcnt, void *buffer); /********************************************************************************* @@ -424,7 +424,7 @@ int do_scsi (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) #define SCSI_MAX_READ_BLK 0xFFFF /* almost the maximum amount of the scsi_ext command.. */ -ulong scsi_read(int device, ulong blknr, ulong blkcnt, ulong *buffer) +ulong scsi_read(int device, ulong blknr, ulong blkcnt, void *buffer) { ulong start,blks, buf_addr; unsigned short smallblks; diff --git a/common/usb_storage.c b/common/usb_storage.c index b4b7914089..196ceb7359 100644 --- a/common/usb_storage.c +++ b/common/usb_storage.c @@ -169,7 +169,7 @@ static struct us_data usb_stor[USB_MAX_STOR_DEV]; int usb_stor_get_info(struct usb_device *dev, struct us_data *us, block_dev_desc_t *dev_desc); int usb_storage_probe(struct usb_device *dev, unsigned int ifnum,struct us_data *ss); -unsigned long usb_stor_read(int device, unsigned long blknr, unsigned long blkcnt, unsigned long *buffer); +unsigned long usb_stor_read(int device, unsigned long blknr, unsigned long blkcnt, void *buffer); struct usb_device * usb_get_dev_index(int index); void uhci_show_temp_int_td(void); @@ -941,7 +941,7 @@ static void usb_bin_fixup(struct usb_device_descriptor descriptor, #define USB_MAX_READ_BLK 20 -unsigned long usb_stor_read(int device, unsigned long blknr, unsigned long blkcnt, unsigned long *buffer) +unsigned long usb_stor_read(int device, unsigned long blknr, unsigned long blkcnt, void *buffer) { unsigned long start,blks, buf_addr; unsigned short smallblks; diff --git a/cpu/pxa/mmc.c b/cpu/pxa/mmc.c index c57d0d5c32..0fbaa162fa 100644 --- a/cpu/pxa/mmc.c +++ b/cpu/pxa/mmc.c @@ -363,7 +363,7 @@ mmc_write(uchar *src, ulong dst, int size) ulong /****************************************************/ -mmc_bread(int dev_num, ulong blknr, ulong blkcnt, ulong *dst) +mmc_bread(int dev_num, ulong blknr, ulong blkcnt, void *dst) /****************************************************/ { int mmc_block_size = MMC_BLOCK_SIZE; diff --git a/drivers/systemace.c b/drivers/systemace.c index 3f329f9708..9502623a74 100644 --- a/drivers/systemace.c +++ b/drivers/systemace.c @@ -73,8 +73,7 @@ /* */ static unsigned long systemace_read(int dev, unsigned long start, - unsigned long blkcnt, - unsigned long *buffer); + unsigned long blkcnt, void *buffer); static block_dev_desc_t systemace_dev = { 0 }; @@ -133,11 +132,11 @@ block_dev_desc_t *systemace_get_dev(int dev) * number of blocks read.
