There's a comment where MEMSAVE is used:

         /* The first 2 words of memory are used to communicate with the
          * bootloader, to tell it how to resume.
          *
          * The first word is the magic number 0xf5153ae5, and the second
          * is the pointer to mpc83xx_deep_resume.
          *
          * The original content of these two words is saved in the state
          * save area.
          */

We could stick a /* First 8 bytes of RAM */ after the #define if you want.
