Subject: env: Move TOTAL_MALLOC_LEN to environment.h
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f030b7b2607013a1b05a696e7f010d5f8dbe4fcd;p=u-boot.git

env: Move TOTAL_MALLOC_LEN to environment.h

This declaration is only used in three files. Although it relates to
malloc() it is actually only used during malloc() init. It uses CONFIG
options including CONFIG_ENV_ADDR which are defined only in environment.h
so this header must be included anyway, for TOTAL_MALLOC_LEN to be
correct.

Nove it to environment.h to simplify the common file.
