[PATCH] Au1200: kill IDE driver function prototypes

Fix these warnings emitted when compiling drivers/ide/mips/au1xxx-ide.c:

include/asm/mach-au1x00/au1xxx_ide.h:137: warning: 'auide_tune_drive' declared 
`static' but never defined
include/asm/mach-au1x00/au1xxx_ide.h:138: warning: 'auide_tune_chipset' declared
 `static' but never defined

by wiping out the whole "function prototyping" section from the header file
<asm-mips/mach-au1x00/au1xxx_ide.h> as it mostly declared functions that are
already dead in the IDE driver; move the only useful prototype into the driver.

Signed-off-by: Sergei Shtylyov <>

I'm not sure thru which tree this should go -- probably thru Linux/MIPS one...

Bart, au1xxx-ide-fix-mwdma-support.patch will probably need to be updated to
remove that added prototype since it won't be needed anymore...
