2013-03-06samsung/exynos5: add display port and framebuffer defines and initializationRonald G. Minnich
These are essential functions for setting up the display port and framebuffer, and also enable such things as aux channel communications. We do some very simple initialization in romstage, mainly set a GPIO so that the graphics is powering up, but the complex parts are done in the ramstage. This mirrors the way in which graphics is done in the x86 size. I've added a first pass at a real device, and put it in the mainboard Kconfig, hoping for corrections. Because startup is so complex, depending on device type, I've created a 'displayport' device that removes some of the complexity and makes the flow *much* clearer. You can actually follow the flow by looking at the code, which is not true on other implementations. Since display port is perhaps the main port used on these chips, that's a reasonable compromise. All parameters of importance are now in the device tree. Change-Id: I56400ec9016ecb8716ec5a5dae41fdfbfff4817a Signed-off-by: Ronald G.

2013-02-19snow: add cpu_cluster and domain resources via devicetree.cbDavid Hendricks
This patch will cause the resource allocator to actually set aside the memory resources using methods in the previous patch. The coreboot table output will include "RAM" entries (there were none before): coreboot memory table: 0. 0000000040400000-00000000bff001ff: RAM 1. 00000000bff00200-00000000bff00fff: CONFIGURATION TABLES 2. 00000000bff01000-00000000bfffffff: RAM Change-Id: I5cd76e93fc232fdae1754253efb4e9269b3a20c0 Signed-off-by: David Hendricks <dhendrix@chromium.org> Reviewed-on: http://review.coreboot.org/2420 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

2012-12-12Add minimal mainboard support for snowRonald G. Minnich
This is the minimal set of sources that allow the board to build. These need to be filled in with actual code. But if we get these in upstream we can stop working against a WIP patch.
