Description
The alt_read_flash() function reads data from flash. length bytes are read from the flash fd, starting
offset bytes from the beginning of the flash and are written to the location dest_addr.
Call this function only when operating in single-threaded mode.
The only valid values for the fd parameter are those returned from the alt_flash_open_dev function. If
any other value is passed, the behavior of this function is undefined.
Return
The return value is zero on success and nonzero otherwise.
