Hi All,
I encountered a problem something like
struct xyz {
int x;
int y;
int z[CONST];
} __attribute__ ((packed));
struct xyz *abc;
u32 * status_reg = (u32 *)&abc->z[0];
writel(status, status_reg);
This writel results in writing byte by byte on the address pointed to by
status_reg.
This problem is visible with both gcc version 4.4.1 as well as 4.5.0
Incidently, the same code works well with 4.2.4
The problem is visible in the usb host driver which uses the packed structures
for
accessing device registers.
Regards
Vipin
