Dear Aneesh V,
In message 4D2B1A90.9030109@ti.com you wrote:

+};
Why exactly do we need the "__attribute__ ((__packed__))" here?
Because a pointer to it has to be passed to ROM code and ROM code wouldn't expect any padding.
But padding would only be needed if there were any alignment requirements requiring it. There are none here.
Best regards,
Wolfgang Denk
