379	 *
380	 * At the time of writing, there are atleast 12 boards, 4 with XLR

382	 * 12 different configurations, with varying levels of differences.
383	 * To accomodate the different configs, the xlr_board_info struct
384	 * has various attributes for paramters that could be different.
385	 * These attributes are setup here and can be used directly in the
386	 * base driver.
387	 * It was seen that the setup code is not entirely trivial and
388	 * it is possible to organize it in different ways. In the following,
389	 * we choose an approach that sacrifices code-compactness/speed for
390	 * readability. This is because configuration code executes once
391	 * per reboot and hence has a minimal performance impact.
392	 * On the other hand, driver debugging/enhancements require
393	 * that different engineers can quickly comprehend the setup
394	 * sequence. Hence, readability is seen as the key requirement for
395	 * this code. It is for the reader to decide how much of this
396	 * requirement is met with the current code organization !!
397	 *
398	 * The initialization is organized thus:

408	 *       // chip-specific overrides
409	 *       // board-specific overrides
410	 * }
411	 *
412	 * For each CPU family, all the default initializations
413	 * are done for a fully-loaded device of that family.
