    xtensa: handle memmap kernel option · 06bd2824
    Max Filippov authored
    This option is useful for reserving memory regions for secondary cores
    in AMP configurations.
    Implement the following memmap variants:
    - memmap=nn[KMG]@ss[KMG]: force usage of a specific region of memory;
    - memmap=nn[KMG]$ss[KMG]: mark specified memory as reserved;
    - memmap=nn[KMG]: set end of memory.
