2016-11-23veyron_*: Remove obsolete ChromeboxesDavid Hendricks
This removes brain, danger, emile, and romy from the tree. This was cherry-picked from the chromeos-2016.02 branch (CL:345574), but conflicts showed up in many files that were to be deleted anyway possibly due to some widespread refactoring that was done between then and now.

2016-11-03google/veyron*: change .ddrconfig from 14 to 3ZhengShunQian
There are two configs, sdram-lpddr3-hynix-2GB.inc and sdram-lpddr3-samsung-2GB-24EB.inc that use .ddrconfig = 14. Changing .ddrconfig from 14 to 3 improves performance especially on contiguous memory accesses. Comparing the .ddrconfig: - if .ddrconfig = 3, C RDRR RRRR RRRR RRRR RBBB CCCC CCCC C--- - if .ddrconfig = 14, C DRBB BRRR RRRR RRRR RRRR CCCC CCCC C--- where - R: indicates Row bits - B: indicates Bank bits - C: indicates Column bits - D: indicates Chip selects bits .ddrconfig = 3 has multiple banks switching which improves DDR timing.

2015-04-21veyron: Sync up SDRAM configurationsJulius Werner
This patch adds all SDRAM configurations currently in use for any Veyron board to all boards. In the future we might decide that we want to reuse known good memory from one board on another, and having all of these in there already might help us avoid a firmware rev. We can still differentiate them later if the need ever arises. Not touching Rialto since it already decided to go its own way and replace an existing RAM code with it's own 1GB configuration. Also adjusting the names of the recently added DDR3 4GB configs to fit the existing scheme. Includes changes from "veyron: The ODT function is disabled LPDDR3". BRANCH=veyron BUG=None TEST=Compiled all Veyron boards, booted on Jerry.
