+Subject: OMAP3: Beagleboard can have dual-chip RAM
+X-Git-Url: http://git.mansr.com/?p=u-boot;a=commitdiff_plain;h=ef6ee5af8d584bddadb2d45ad4320cef96b8a934;hp=caccdb772c3028a3e3e801fb1554788150752ffc
+
+OMAP3: Beagleboard can have dual-chip RAM
+
+Some Beagleboards are fitted with dual-chip RAM. Returning DDR_STACKED
+from get_mem_type() causes the second chip (on CS1) to be enabled.
+
+FIXME: need a better way to configure this.
