Hello aarch64 experts,

Since commit 3865ceb (vexpress/armv7: Fix incorrect ethernet controller), I have many warning messages when I compile vexpress board.

smc91111.c: In function ?poll4int?:
smc91111.h:252:25: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

 #define SMC_inw(a,r) (*((volatile word *)((a)->iobase+(r))))
                         ^
smc91111.c:242:18: note: in expansion of macro ?SMC_inw?
  word old_bank = SMC_inw (dev, BSR_REG);
                  ^
smc91111.h:261:28: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
 #define SMC_outw(a,d,r) (*((volatile word *)((a)->iobase+(r))) = d)
                            ^

smc91111.h:747:33: note: in expansion of macro ?SMC_outw?
#define SMC_SELECT_BANK(a,x) { SMC_outw((a), (x), BANK_SELECT ); }

Best Regards

Hello aarch64 experts,
Since commit 3865ceb (vexpress/armv7: Fix incorrect ethernet controller), I have many warning messages when I compile vexpress board.
smc91111.c: In function 'poll4int':
smc91111.h:252:25: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] #define SMC_inw(a,r) (*((volatile word *)((a)->iobase+(r))))
                         ^
smc91111.c:242:18: note: in expansion of macro 'SMC_inw'
  word old_bank = SMC_inw (dev, BSR_REG);
                  ^
smc91111.h:261:28: warning: cast to pointer from integer of different

These are issues with the SMSC91c111 driver highlighted when trying to compile for ARM64. I can try to fix the same, but will need some time to do the same, plus I don't have additional platforms to test the same.
