03831d35f7499c87d51205817c93e9a8d42c4baestevel * When an ECC error occurs on an E$ DIMM, the error handling code requests a
03831d35f7499c87d51205817c93e9a8d42c4baestevel * unum to provide a human-readable physical location to the part that
03831d35f7499c87d51205817c93e9a8d42c4baestevel * experienced the error.
03831d35f7499c87d51205817c93e9a8d42c4baestevel * Previously, on Serengeti and LW8, a prom call was made to get this
03831d35f7499c87d51205817c93e9a8d42c4baestevel * information. However, calling COBP to do a simple string format is
03831d35f7499c87d51205817c93e9a8d42c4baestevel * inefficient. All the necessary information is now kept here.
03831d35f7499c87d51205817c93e9a8d42c4baestevel * Since this data is now kept in two places (COBP and here), care must be
03831d35f7499c87d51205817c93e9a8d42c4baestevel * taken so that the two locations are kept the same. Any changes to the
03831d35f7499c87d51205817c93e9a8d42c4baestevel * jnumber array will require a change to COBP code so that the two arrays
03831d35f7499c87d51205817c93e9a8d42c4baestevel * match. Any changes to the unum string format will require changes in both
03831d35f7499c87d51205817c93e9a8d42c4baestevel * the COBP code (to match the code here) and plat_ecc_unum.c (to read the
03831d35f7499c87d51205817c93e9a8d42c4baestevel * new format). These changes should not be necessary, except to reflect a
03831d35f7499c87d51205817c93e9a8d42c4baestevel * new cpu or board type.
03831d35f7499c87d51205817c93e9a8d42c4baestevel * The following array holds the jnumbers for Ecache DIMMs. The first index
03831d35f7499c87d51205817c93e9a8d42c4baestevel * is the proc position on the board (0 through 3) and the second index is
03831d35f7499c87d51205817c93e9a8d42c4baestevel * the DIMM number (0 or 1).
