Subject: ARM: tegra: stingray: use generic memory vendor matching
X-Git-Tag: firefly_0821_release~9834^2~66
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ae2833c5e5ce0e62a20aa5dea7e189f9aa7219c5;p=firefly-linux-kernel-4.4.55.git

ARM: tegra: stingray: use generic memory vendor matching

Initialize arrays to utilize new signature of tegra_init_emc.
Memory types are matched internally and command line
option is no longer needed.
