Laszlo Ersek 9f75aacc7a UefiCpuPkg/ResetVector/Vtf0: document segment register setup
"Main.asm" calls TransitionFromReal16To32BitFlat (and does some other
things) before it jumps to the platform's SEC entry point.

TransitionFromReal16To32BitFlat enters big real mode, and sets the DS, ES,
FS, GS, and SS registers to offset ("selector") LINEAR_SEL in the GDT
(defined in "UefiCpuPkg/ResetVector/Vtf0/Ia16/Real16ToFlat32.asm"). The
GDT entry ("segment descriptor") at LINEAR_SEL defines a segment covering
the full 32-bit address space, meant for "read/write data".

Document this fact for all the affected segment registers, as output
parameters for TransitionFromReal16To32BitFlat, saying "Selector allowing
flat access to all addresses".

For 64-bit SEC, "Main.asm" calls Transition32FlatTo64Flat in addition,
between calling TransitionFromReal16To32BitFlat and jumping to the SEC
entry point. Transition32FlatTo64Flat enters long mode. In long mode,
segmentation is largely ignored:

- all segments are considered flat (covering the whole 64-bit address
  space),

- with the (possible) exception of FS and GS, whose bases can still be
  changed, albeit with new methods, not through the GDT. (Through the
  IA32_FS_BASE and IA32_GS_BASE Model Specific Registers, and/or the
  WRFSBASE, WRGSBASE and SWAPGS instructions.)

Thus, document the segment registers with the same "Selector allowing flat
access to all addresses" language on the "Main.asm" level too, since that
is valid for both 32-bit and 64-bit modes.

(Technically, "Main.asm" does not return, but RBP/EBP, passed similarly to
the SEC entry point, is already documented as an output parameter.)

Gao, Liming 9ddb2a2341 UefiCpuPkg: INF/DEC file updates to EDK II packages
2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module.
a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion.

3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.

Jordan Justen 3449f56dac UefiCpuPkg: Add ResetVector/FixupVtf
This implements the older VTF ResetVector code often used on EDK II
IA32 & X64 platforms.

This VTF requires build time fixups in order to find the SEC entry
point. The BaseTools GenFv tool has code that patches the jump target
of the reset vector code to match the entry point of the SEC image in
the PEI Firmware Volume.

v2:
 * Rename from OldVtf to FixupVtf
 * Use EDK II extension of .nasmb rather than .nasmbin

Jordan Justen a63f2e2450 UefiCpuPkg/ResetVector/Vtf0: Move Page Table/CR3 setting to a new file
Now, Transition32FlatTo64Flat calls SetCr3ForPageTables64
which is located in Ia32/PageTables64.asm.

This change is required so OVMF can replace the code in
Ia32/PageTables64.asm with code that generates page tables in
RAM.

Note: Since this change does not impact the functionality of the
current VTF0 binaries, they are not being updated. The resulting
new binaries were tested to verify there is no regression.
