Hi York,
It is not good idea to change the values of all macro at this time as the code
tested on different platforms.
If required, I will remove the TODO statement.
What you say.
Thanks

Changes in v2:
Clean up the code after Scott comments,
Previously in v1, we was defining the pointer as u32,
then casting it to u8, and then passing it to
a 16-bit accessor.
Changes in v3:
Change CONFIG_XXX to CONFIG_ARCH_XXX
