4ff333b7dd x86: fsp: Add FSP_GRAPHICS_INFO_HOB
This adds a new HOB type for graphics information introduced in FSP
spec 1.1. When graphics capability is included in FSP and enabled,
FSP produces an FSP_GRAPHICS_INFO_HOB as described in the EFI PI
specification which provides information about the graphics mode and
framebuffer.

bb737ced7f x86: fsp: Update struct common_buf for FSP spec 1.1
FSP spec 1.1 adds one more member to the struct common_buf to
determine the memory size that can be reserved by FSP below "top
of low usable memory" for bootloader usage. This new member uses
the reserved space so that it is still compatible with previous
FSP spec 1.0.

A new HOB (FSP_HOB_RESOURCE_OWNER_BOOTLOADER_TOLUM_GUID) is also
published when common_buf.tolum_size is valid and non zero.

4ce022d396 x86: fsp: Move struct fspinit_rtbuf definition to chipset header
All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf
as defined by the 1.0 spec, however there are FSPs that does not
follow 1.0 spec (possible due to that FSP predates the 1.0 spec),
and future FSP binary that is complaint to v1.1 spec defines an
optional paltform-specific runtime data in the struct fspinit_rtbuf.
Hence move the definition to chipset header.

81f84aa6c9 x86: fsp: Rename update_fsp_upd() and change its signature
To support platform-specific configurations (might not always be
UPD on some platform), use a better name update_fsp_configs() and
accepct struct fsp_config_data as its parameter so that platform
codes can handle whatever configuration data for that FSP.

cb379a34c4 x86: fsp: Rename shared_data to fsp_config_data
FSP has several config data like UPD, HDA verb table which can be
overridden or provided by bootloader. Currently in U-Boot only UPD
is handled via struct shared_data. To accommodate any platform, we
rename shared_data to fsp_config_data and move the definition from
common place fsp_support.h to platform-specific place fsp_configs.h.

412400abaa x86: Split out fsp_init_phase_pci() code into a new function
This code may be useful for boards that use driver model for PCI.

Note: It would be better to have driver model automatically call this
function somehow. However for now it is probably safer to have it under
board control.

867a6ac86d efi: Add start-up library code
When running as an EFI application, U-Boot must request memory from EFI,
and provide access to the boot services U-Boot needs.

Add library code to perform these tasks. This includes efi_main() which is
the entry point from EFI. U-Boot is built as a shared library.

82196cf34f x86: Adjust the FSP types slightly

to two API functions which use that convention. UPD_TERMINATOR is common
