- * Procedure  :   Download code into IMEM or DMEM

- *				The routine copy virtual address get from opening of file into shared memory
- *				allocated during initialization. If code size larger than a conitneous shared
- *				memory may contain, the code should be divided into several section.
- *				!!!NOTES This finction should only be called during MPInitialization because
- *				A NIC driver should call NdisOpenFile only from MiniportInitialize.
- * Arguments :    The pointer of the adapter
- *			   Code address (Virtual address, should fill descriptor with physical address)
- *			   Code size
- * Returns  :
- *        RT_STATUS_FAILURE - the following initialization process should be terminated
- *        RT_STATUS_SUCCESS - if firmware initialization process success
