27 | * The following data structure is placed in some memory wich is | |
28 | * available very early after boot (like DPRAM on MPC8xx/MPC82xx, or | |
29 | * some locked parts of the data cache) to allow for a minimum set of | |
30 | * global variables during system initialization (until we have set | |
31 | * up the memory controller so that we can use RAM). | |
