That would be better than 0x10, but even better would be just copying
struct socfpga_reset_manager {
u32 status;
u32 ctrl;
u32 counts;
u32 padding1;
u32 mpu_mod_reset;
u32 per_mod_reset;
u32 per2_mod_reset;
u32 brg_mod_reset;
};
from u-boot. Unlike macros, structs have advantages that typos lead to
easier-to-see failure modes... (And they are easier to read/parse,
too).
Thanks,
Pavel
