      powerpc/85xx: Introduce CONFIG_SYS_EXTRA_ENV_RELOC · a55bb834
      Kumar Gala authored
      
      Some systems need to relocate the env_addr pointer early because the
      location it points to will get invalidated before env_relocate is
      called.  One example is on systems that might use a L2 or L3 cache
      in SRAM mode and initialize that cache from SRAM mode back to being
      a cache in cpu_init_r.
      
      We set this on the 85xx boards that have support for NAND, SPI, or
      SDHC/MMC boot support as they use a secondary cache in SRAM mode and
      need the env_addr pointer relocated since we change from SRAM to normal
      cache mode in cpu_init_r.
      
      Also removed CONFIG_SYS_SPL as its not used anywhere.
