From 15c98b021771d10c4bb98e5b0e8cb910cd0c1f7d Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Thu, 1 May 2014 14:45:56 -0700 Subject: storm/ipq8064: add dynamic CBMEM support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Squashed the correction patch with the original to avoid confusion in coreboot.org review. All what's needed apart from configuring the feature is to provide a function which would report the top of DRAM address. BUG=chrome-os-partner:27784 TEST=manual . with all other patches applied, the image proceeds all the way to trying to download 'fallback/payload'.

Proper DRAM base address definition is also necessary so that CBMEM is placed in the correct address range (presently at the top of DRAM). BUG=chrome-os-partner:27784 TEST=build boot coreboot on ap148, observe the following in the console output: Wrote coreboot table at: 5fffd000, 0xe8 bytes, checksum 44a5 coreboot table: 256 bytes.
