Subject: x86: Use the standard dram_init() function
X-Git-Tag: v2015.01-rc2~5^2~43
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=07387d1769c7cc29ff2402117148477263c4c5ce;p=u-boot

x86: Use the standard dram_init() function

Instead of having an x86-specific DRAM init function, adjust things so we
can use the normal one.
