x86: SMM Module Support Add support for SMM modules by leveraging the RMODULE lib. This allows for easier dynamic SMM handler placement. The SMM module support consists of a common stub which puts the executing CPU into protected mode and calls into a pre-defined handler. This stub can then be used for SMM relocation as well as the real SMM handler. For the relocation one can call back into coreboot ramstage code to perform relocation in C code. The handler is essentially a copy of smihandler.c, but it drops the TSEG differences. It also doesn't rely on the SMM revision as the cpu code should know what processor it is supported. Ideally the CONFIG_SMM_TSEG option could be removed once the existing users of that option transitioned away from tseg_relocate() and smi_get_tseg_base(). The generic SMI callbacks are now not marked as weak in the declaration so that there aren't unlinked references. The handler has default implementations of the generic SMI callbacks which are marked as weak. If an external compilation module has a strong symbol the linker will use that instead of the link one. Additionally, the parameters to the generic callbacks are dropped as they don't seem to be used directly. The SMM runtime can provide the necessary support if needed.

Make the device tree available in the rom stage We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area.
