Subject: [ARM] pxa: Make cpu_is_pxaXXX dependent on configuration symbols
X-Git-Tag: upstream/snapshot3+hdmi~30577^2^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=36d8b17b4364915615aff312ba20a1b90e22b963;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[ARM] pxa: Make cpu_is_pxaXXX dependent on configuration symbols

Make the cpu_is_pxaXXX() macros define to zero when support for a
particular CPU is disabled.  This allows us to eliminate code for
CPUs which aren't enabled.
