    MIPS: Reserve space for relocation table · 069fd766
    Matt Redfearn authored
    When CONFIG_RELOCATABLE is enabled, add a new section in the memory map
    to be filled with relocation data.
    
    CONFIG_RELOCATION_TABLE_SIZE allows the amount of space reserved to be
    adjusted if necessary.
    
    The relocs tool will populate this reserved space with relocation
    information. The space is reserved within the elf by filling it with
    0's, and an invalid entry is left at the start of the space such that
    kernel relocation will be aborted if the table is empty.
