2019-07-13fit_payload: Always set DT sizeJulius Werner
CB:32870 changed FIT loading code to make an FDT mandatory (because the platforms that can use FIT images always need an FDT). Remove one left-over conditional that is now dead code. Found by Coverity.

2019-06-21fit: Add overlay supportJulius Werner
This patch adds support to boot FIT image configurations consisting of a base device tree and one or more overlays. Since extracting the right compatible string from overlay FDTs is problematic, we'll only support this for FIT images that have the compatible string pulled out into the config node. This patch was adapted from depthcharge's http://crosreview.com/1555293 Change-Id: I0943f9a1869c9e416887c7ff16e33f7d91b74989 Signed-off-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32873 Reviewed-by: Hung-Te Lin <hungte@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2019-06-21fit: Add device tree compressionJulius Werner
This patch adds support for compressing individual device trees in the FIT image. In order to make this efficient, we'll have to pull the compatible property out of the FDT and store it directly in the config node of the FIT image, so that we don't have to scan (and therefore decompress) every single FDT on boot. Device tree compression is only supported for FIT images that have this external compatible property. For older images with no compression, we still support fallback to scanning the FDT for the property.

2019-06-21fit_payload: Don't call prog_segment_loaded() on extracted imagesJulius Werner
Kernel handoff on all architectures supporting FIT images already includes flushing and disabling the cache. No need to waste any more time flushing individual components (especially since in the case of compressed DT overlays they will still get accessed again afterwards).

2019-06-21fit: Refactor config node handlingJulius Werner
This patch makes some minor refactoring to the way the FIT parser handles config nodes. A lot of this code was written in the dawn age of depthcharge when its device tree library wasn't as well-stocked yet, so some of it can be rewritten nicer with more high-level primitives. There's no point in storing both the string name and the actual FDT node of a FIT image node separately, since the latter also contains the former, so remove that. Also eliminate code for the case of not having an FDT (which makes no sense), and move some more FDT validity/compat checking into fit_update_compat() (mostly in anticipation of later changes). This patch was adapted from depthcharge's http://crosreview.com/1553456 with a couple of modifications specific to coreboot's custom FIT loading code.
