Subject: armv8: Support not having separate BSS
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a3403e6fbf80412a04ddbb033b3235aa03b04efa;p=u-boot.git

armv8: Support not having separate BSS

Separate BSS is current mandatory on armv8 but this is not useful for
early boot phases. Add support for the combined BSS.

Use an #ifdef to avoid using CONFIG_SPL_BSS_START_ADDR which is not
valid in this case.
