1. Update edksetup.bat and toolsetup.bat to handle PACKAGES_PATH.
BaseTools directory may be in PACKAGES_PATH instead of WORKSAPCE.
2. Introduce EDK_TOOLS_BIN env points to the windows binary tools dir.
Windows BaseTools Win32 may be a separate directory.

As it turns out, upstream GCC only supports the AArch64 'tiny' code
model as of version 4.9. Since the default 'small' code model requires
4 KB section alignment (which is undesirable for the XIP modules),
revert GCC 4.7 and 4.8 to using the 'large' code model instead.

Disable the RVCT size optimization that may put sections at an offset
that is not aligned to their own alignment, by adding the --no_legacyalign
switch to the RVCT linker command line. This is necessary since such sections
cannot be correctly converted into PE/COFF sections without padding them at
the front, which defeats the purpose of the optimization anyway.
With the optimization gone, we can also remove the special case for ARM in
GenFw that could result in corrupt PE/COFF images to be emitted. Instead,
sections whose base address is not aligned correctly are outright rejected.

The AARCH64 tiny code model produces more efficient code, since it
uses relative symbol references rather than absolute references, i.e.,
an emitted relative reference refers to the symbol directly rather
than a literal containing its 64-bit absolute address. This saves
space in the binary, and reduces the number of relocation fixups that
need to be applied by the PE/COFF loader.
So now that we support relative relocations in GenFw, move to the
tiny code model by default. Note that the large model can still be
selected by individual modules by adding -mcmodel=large to the
appropriate CC_FLAGS.

In GCC 4.7, a feature was added to the ARM backend that allows
unaligned loads and stores to be emitted. Since it is enabled by
default on ARMv6 and later CPUs, and since such code is not suitable
in our case (i.e., bare metal code), we must disable it by passing the
-mno-unaligned-access option if we are using GCC 4.7 or later.
However, this particular feature and its enabling by default have been
backported to version 4.6 by Linaro. Since the Linaro toolchains are
widely used for ARM development, and also shipped by distros such as
Ubuntu, we should disable the feature on version 4.6 as well.
Unfortunately, since the upstream version does not support the feature,
it also does not understand the -mno-unaligned-access option.
Since GCC sets the builtin #define __ARM_FEATURE_UNALIGNED to 1 when
-munaligned-access is in effect, we can force the build to fail in this
case by passing -D__ARM_FEATURE_UNALIGNED=0 on the GCC command line.
This will produce the following error message:
<command-line>:0:0: error: "__ARM_FEATURE_UNALIGNED" redefined [-Werror]
<built-in>:0:0: note: this is the location of the previous definition
and terminate the build.
This patch may cause some existing builds to fail, but they will be
builds that were previously at risk of unexpected runtime exceptions.
Those builds can also easily be switched to the GCC47 profile instead,
generating safe binaries.

After the recent GNU linker script changes, the following warning is
emitted many times during the OVMF build:
BFD: <...>: warning: Empty loadable segment detected, is this intentional ?
This is caused by the fact that, now that the section layout has changed
somewhat, the .eh_frame section is assigned an ELF segment of its own,
which ends up with no contents at all after we strip the .eh_frame
section from the output. (Note that the program headers that contain the
segment information are completely irrelevant to us since the PE/COFF
conversion does not rely on them.)
Since we only retain the .eh_frame data for external debugging, and not
for things like stack unwinding or generating backtraces at runtime, we
can remedy the situation by passing -fno-asynchronous-unwind-tables on
the GCC command line. This option instructs the compiler to emit the
unwind data into a debug section called .debug_frame instead of into
.eh_frame.

The AArch64 small C model makes extensive use of ADRP/ADD and
ADRP/{LDR,STR} pairs to emit PC-relative symbol references with
a +/- 4 GB range. Since the relocation pair splits the relative
offset into a relative page offset and an absolute offset into
a 4 KB page, we need to take extra care to ensure that the target
of the relocation preserves its alignment relative to a 4 KB
alignment boundary.
Also, due to a problem with the --emit-relocs GNU ld option, where
it does not recalculate the addends for section relative relocations,
the only way to guarantee correct code is by requiring the relative
section offset to be equal in the ELF and PE/COFF versions of the
binary. This affects both the 'tiny' and 'small' GCC code models.

All AutoGen.obj files consist of global GUID definitions, fixed
and patchable PCDs and other data that is essentially read-only at
runtime but has not been declared as such for various reasons.
By moving these contents to .text we achieve two things:
- global GUIDs and other data items which must be constant for correct
program operation can no longer be modified, for instance, when
running a DXE_RUNTIME_MODULE binary under the OS with the Properties
Table feature for memory protection enabled;
- the .data section becomes smaller, and may be dropped completely for
many XIP modules, which reduces wasted FV space if the PE/COFF section
alignment is large.

Now that GenFw honors the ELF section alignment when placing the
PE/COFF sections in the output, the start of the PE/COFF version of
.data will be aligned to the alignment of .text if its alignment is
higher than the default. So duplicate this behavior in the ELF output,
this will make the memory layout of the PE/COFF binary match the
layout of the ELF version more closely.

This unifies all GCC linker scripts into a single parametrised GCC
linker script that can be used for all GCC versions and architectures.
The two parameters that can be set on the linker command line are:
- PECOFF_HEADER_SIZE, this is a build time property of GenFw, but
its value is different between 32-bit and 64-bit;
- common-page-size, this can be set using -z on the ld command line,
and controls the value of the COMMONPAGESIZE constant when used in
a linker script. This value is used for the minimum section alignment.

Instead of hardcoding the values for the PE/COFF header size and the
section alignment, set them on the linker command line. This factors
out these values from the various linker scripts, which will allow us
to unify them in a subsequent patch.

Move the .got contents to the PE/COFF .text section. This should be
a no-op, since we typically don't generate position independent code
(i.e., using -fPIC). But since the GOT contains variable addresses that
are updated at relocation time only, its contents are best kept in .text
to prevent them from being overwritten inadvertently.

The .rodata ELF section contains constant non-executable data that
should never be modified by the program itself. Since the risk of
inadvertent modification is typically higher than the risk of
inadvertent execution, it makes sense to put this data in the
R-X .text section rather than in the RW- .data section.
So move it there.

The NOP padding in the GCC linker scripts ensures that all empty
regions in the ELF binary are filled with x86 NOP instructions.
There is no upside to doing this: if the CPU ends up executing these
instructions, we have little hope of resuming normal execution of the
program anyway. And having NOP slides in memory only makes it easier
for attackers to launch exploits. So remove them.

To prevent double padding of XIP modules leading to excessive
waste of FV space, try to adjust existing padding rather than
adding more.
Instead of adding a pad file to the FV to line up an FFS file that
itself may contain padding to line up the payload, try to find a
dedicated padding section inside the FFS, and reduce its size to
place all subsequent aligned FFS section at their respective minimum
alignments.
When using 4 KB section alignment (which is required on AARCH64 in
some cases), this will save 4 KB for each XIP module.

Instead of using an anonymous section of type EFI_SECTION_RAW to pad
out the first aligned FFS section to its required alignment, use a
section with a dedicated GUID if the size of the padding permits it.
This allows for more flexibility when placing such FFS images in a
firmware volume, because we will now be able to remove padding rather
than add more, by shrinking the size of this section instead of
padding out the start of the FFS image to file alignment.

The secondary header (not the DOS header) of a PE/COFF binary
does not reside at a fixed offset. Instead, its offset into the
file is recorded in the DOS header.
This gives us the flexibility to move it, along with the section
headers, to right before the first section if there is considerable
space before it, i.e., when the PE/COFF file alignment is substantially
larger than the size of the header.
Since the PE/COFF to TE conversion replaces everything before the
section headers with a simple TE header, this change removes all
the header padding from such images, leading to smaller files.

In order to reduce the memory footprint of PE/COFF images when
using large values for the PE/COFF section alignment, move the
contents of the .debug section to data, and point the debug data
directory entry to it. This allows us to drop the .debug section
entirely, as well as any associated rounding. Since our .debug
section only contains the filename of the ELF input image, the
penalty of keeping this data in a non-discardable section is
negligible.
Note that the PE/COFF spec v6.3 explicitly mentions that this is
allowed.

When a quoted string is used as initialization data in a DEC file PCD
entry, the PCD data type in that entry must be VOID*. The created
AutoGen.c defines the PCD data as UINT8[] or UINT16[], depending on
the string type. The created AutoGen.h, however, declares the PCD data
as VOID*. For a standard compile/link, this works because AutoGen.c
doesn't include AutoGen.h. But when GCC LTO is used, the link time
code generation detects the mismatch and the build fails. This
change makes the AutoGen.h PCD data declaration match the AutoGen.c
definition.
