6.24.3 Boot Parameter Table
The ROM Bootloader (RBL) is guided by the boot parameter table to carry out the boot process. The boot
parameter table is the most common format the RBL employs to determine the boot flow. These boot
parameter tables have certain parameters common across all the boot modes, while the rest of the
parameters are unique to the boot modes. Table 6-73 lists the common entries in the boot parameter
table.
