Compiling dbau1x00 and gth2 boards with GCC-4.2, you would see new warnings like this: skuribay@ubuntu:u-boot.git$ ./MAKEALL dbau1000 Configuring for dbau1x00 board... au1x00_eth.c: In function 'au1x00_send': au1x00_eth.c:158: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type au1x00_eth.c: In function 'au1x00_recv': au1x00_eth.c:211: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type au1x00_eth.c: In function 'au1x00_init': au1x00_eth.c:252: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type au1x00_eth.c: In function 'au1x00_recv': au1x00_eth.c:211: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type au1x00_eth.c: In function 'au1x00_init': au1x00_eth.c:252: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type au1x00_eth.c: In function 'au1x00_send': au1x00_eth.c:158: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type We're passing a volatile pointer to a function which is expecting a non- volatile pointer. That's potentially dangerous, so gcc warns about it. Confirmed with ELDK 4.2 (GCC 4.2.2) and Sourcey G++ 4.2 (GCC 4.2.3). To fix this, we add a volatile attribute to the argument in question. The virt_to_phys function in Linux kernel also does the same thing. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp> |
