[U-Boot] [PATCH v4 31/37] Makefile: Do not pass MTD_VERSION from the top Makefile

[Masahiro Yamada]

$(MTD_VERSION) is used in tools/env/Makefile

If you specify a variable at a command line like:
  $ make MTD_VERSION=old env
or specify it thru an envrionment variable like:
  $ export MTD_VERSION=old
  $ make env
it is inherited to the sub-make too.
We do not need to pass it from the top Makefile explicitely.
