This patch series moves the configuration of FPS-S and FSP-M for Apollo Lake based SoCs from the code to the devicetree.
In order to make the FSP configuration easy to extend and maintain new binding structs for FSP-M and FSP-S are introduced. These structs contain the information of which devicetree settings need to be copied to which offset in the FSP config structure. The actual code handling these structs is rather small, and generic for both FSP-S and FSP-M.
This patch series replaces the previous sent patches: "arch: x86: apl: Read FSP-M configuration from device-tree" [1] "Move FSP-S configuration to device-tree" [2]
Changes to [1] and [2]: - No default settings within U-Boot, the default settings in FSP are used directly - The code for copying the data was simplified, and the information of what needs to be copied was moved to newly introduced structures

Changes in v2: Integration of the review comments Fix swizzle size bug
Bernhard Messerklinger (2): arch: x86: apl: Only load VBT if CONFIG_HAVE_VBT is enabled arch: x86: apl: Use devicetree for FSP configuration
