I'm porting u-boot on our arm1176-based SoC which uses greth as ethernet controller. I have removed sparc code from greth.c and now almost ready to send the patch. Last thing to fix is cache flusher function which is required by the driver. Originally algorithm used sparc_flush_cachces which is not suitable for the driver.
Is there any 'official' guidelines on using the caches? What hardware-abstract function should I prefer?
if the func is defined in include/*.h, it tends to be OK to use portability (ignoring the arch-specific files which shouldnt be in include/). in terms of cache, a simple grep tells you the answer: grep cache include/common.h -mike
