Patch set updated for coreboot: 7da593e Make DSDT a file in CBFS rather than embedding it into ramstage.
Vladimir Serbinenko (phcoder@gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10385 -gerrit commit 7da593e3af2275a2e812590ebca80030dcf34294 Author: Vladimir Serbinenko <phcoder@gmail.com> Date: Sun May 31 12:31:59 2015 +0200 Make DSDT a file in CBFS rather than embedding it into ramstage. Makes it cleaner by putting AML into separate file rather than having an array in C code.
