commit ae5c9e1e372c0f445108362e1b0070aeeca6c134 Author: Furquan Shaikh furquan@google.com Date: Thu Jun 26 00:11:29 2014 -0700
coreboot rush: Add support for basic romstage
Add basic romstage support for rush. Since, dram init needs to be done before we can jump to armv8 core, romstage will run on armv4 core as well. Thus, correcting the compiler selection options.
BUG=None BRANCH=None TEST=Compiles successfully for rush. Prints romstage banner and initial printk
