2015-10-11intel fsp1_1: prepare for romstage vboot verification splitAaron Durbin
In order to introduce a verstage which performs vboot verification the cache-as-ram environment needs to be generalized and split into pieces that can be utilized in romstage and/or verstage. Therefore, the romstage pieces were removed from the cache-as-ram specific pieces that are generic: - Add fsp/car.h to house the declarations for functions in the cache-as-ram environment - Only have cache_as_ram_params which are isolated form the cache-as-ram environment aside from FSP_INFO_HEADER. - Hardware requirements for console initialization is done in the cache-as-ram specific files. - Provide after_raminit.S which can be included from a romstage separated from cache-as-ram as well as one that is tightly coupled to the cache-as-ram environment. - Update the fallout from the API changes in soc/intel/{braswell,common,skylake}.

2015-10-11intel: update common and FSP cache-as-ram parametersAaron Durbin
Instead of just passing bits, tsc_low, tsc_high, and an opaque pointer to chipset context those fields are bundled into a cache_as_ram_params struct. Additionally, a new struct fsp_car_context is created to hold the FSP information. These could be combined as the existing romstage code assumes what the chipset_context values are, but I'm leaving the concept of "common" alone for the time being. While working in that area the ABI between assembly and C code has changed to just pass a single pointer to cache_as_ram_params struct. Lastly, validate the bootloader cache-as-ram region with the Kconfig options. BUG=chrome-os-partner:44676 BRANCH=None TEST=Built and booted glados.

2015-10-02fsp1_1: move relocation algorithm to commonlibAaron Durbin
In order to support FSP 1.1 relocation within cbfstool the relocation code needs to be moved into commonlib. To that end, move it. The FSP 1.1 relocation code binds to edk2 UEFI 2.4 types unconditionally which is separate from the FSP's version binding. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados.

2015-09-22coreboot: introduce commonlibAaron Durbin
Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.

2015-09-10fsp1_1: provide binding to UEFI versionAaron Durbin
FSP has some unique attributes which makes integration cumbersome: 1. FSP header files do not include the types they need. Like EDKII development it's expected types are provided by the build system. Therefore, one needs to include the proper files to avoid compilation issues. 2. An implementation of FSP for a chipset may use different versions of the UEFI PI spec implementation. EDKII is a proxy for all of UEFI specifications. In order to provide flexibility one needs to binding a set of types and structures from an UEFI PI implementation. 3. Each chipset FSP 1.1 implementation has a FspUpdVpd.h file which defines it's own types. Commonality between FSP chipset implementations are only named typedef structs. The fields within are not consistent. And because of FSP's insistence on typedefs it makes it near impossible to forward declare structs. The above 3 means one needs to include the correct UEFI type bindings when working with FSP. The current implementation had the SoC picking include paths in the edk2 directory and using a bare <uefi_types.h> include. Also, with the prior fsp_util.h implementation the SoC's FSP FspUpdVpd.h header file was required since for providing all the types at once (Generic FSP 1.1 and SoC types). The binding has been changed in the following manner: 1. CONFIG_UEFI_2_4_BINDING option added which FSP 1.1 selects. No other bindings are currently available, but this provides the policy. 2. Based on CONFIG_UEFI_2_4_BINDING the proper include paths are added to the CPPFLAGS_common. 3. SoC Makefile.inc does not bind UEFI types nor does it adjust CPPFLAGS_common in any way. 4. Provide a include/fsp directory under fsp1_1 and expose src/drivers/intel/fsp1_1/include in the include path. This split can allow a version 2, for example, FSP to provide its own include files. Yes, that means there needs to be consistency in APIs, however that's not this patch. 5. Provide a way for code to differentiate the FSP spec types (fsp/api.h) from the chipset FSP types (fsp/soc_binding.h). This allows for code re-use that doesn't need the chipset types to be defined such as the FSP relocation code. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted on glados.
