Subject: arm-trusted-firmware-mediatek: use MT/s as DDR speed unit
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=79dac8f57c75858a277bceed00216091ba7e84fa;p=openwrt%2Fopenwrt.git

arm-trusted-firmware-mediatek: use MT/s as DDR speed unit

Usually we do not use MHz to describe the DDR transmission rate. In
fact, the clock frequency of the DDR3-1866 is only 933 MHz. MT/s is
a more commonly used unit.
