Subject: [PATCH] ARM: davinci_all_defconfig: enable CMA options

Enable the CMA and DMA_CMA Kconfig options by default for
Davinci platforms. Davinci remoteproc driver is one of the
modules that depends on these options, and this allows the
driver to be made visible for selection with menuconfig.

Hi Sekhar,

Here's the patch that enables CMA as per your request. Patch based
on your v4.15/defconfig branch.

regards
Suman
