[ECOS] Big endian ARM HAL_WRITE_UINT8 problem (ecos 1.3.1)

I'm working with a big endian arm chip and am having problems with the
HAL_WRITE_UINT8 macro.

If I do something like:

#define HW_REG_ADDRESS \
    ((volatile cyg_uint8*) (0x0400c71f))


HAL_WRITE_UINT8(HW_REG_ADDRESS, 0xff);


It ends up writing to address 0x0400c71c and not 0x0400c71f.  I could just
take the ^3 out of the macro, but am concerned that it might cause problems.
Does anyone have any suggestions?

Thanks,

Dirk
