The boot parameter tables direct the main module boot process. On cold boot the tables are created based on pin strapped values (see Section 4.3, Boot Mode Pins) and built-in data. The ROM Code supports two parameter tables stored as an array in a fixed memory address in the MSRAM, each of size 512 bytes. The ROM will attempt to boot using the primary table. On boot failure, ROM Code will retry using the second table.
Using two tables handles two cases.
The boot tables reside at a fixed location in memory which is described in Section 4.8.2, Global Memory Addresses Used by ROM Code.
