;****************************************************************************
;* FILE PURPOSE: Code a simple endian independent example
;****************************************************************************
;* FILE NAME: Simple.s
;*
;* DESCRIPTION: This program is part of the Himalaya I2C boot test plan.
;* It is a simple program that defines two initialized
;* sections, text and data, and performs a simple
;* execution with a self check on the results in register a0.
;*
;* The code is also designed to be relocatable, so it will
;* function in the himsim program running on the DM642.
