Subject: [POWERPC] rheap: Changes config mechanism
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1088a20998a1091b22b42cf3dc2f5f1be4faaead;p=linux-beck.git

[POWERPC] rheap: Changes config mechanism

Instead of having in the makefile all the option that
requires rheap, we define a configuration symbol
and when needed we make sure it's selected.
