value(config) of sdram. Such as size, speed, and etc.<br>
</font></p>
<p><font face="굴림체"><br>
</font></p>
<p><font face="굴림체">So, I'm try to search and study the coreboot
source code, and found out the
"vendorcode/intel/fsp1_0/rangeley/include/fspplatform.h"</font></p>
<p><font face="굴림체"><br>
</font></p>
<p><font face="굴림체">This header are contained the some structure for
setup the sdram. such as "MEM_DOWN_DIMM_SPD_DATA;"</font></p>
<p><font face="굴림체"><br>

</font></p>
<p><font face="굴림체">So, I'm try to found <b>*.c</b> source codes

<p><font face="굴림체">But, coreboot are not setup the argument of
sdram.</font></p>
<br>
<font face="굴림체">I don't understand this sisution, Because sdram is
must need a some configuration for use.<br>
<br>
<br>
<b>Why? do not setup the argument of sd</b><b>ram ???<br>
