Recent versions of GNU ld automatically emit a .notes section into
the ELF binary containing a build id. Since this is an allocatable
section by default, it will be identified by GenFw as a section
that requires PE/COFF conversion, which may cause sections to be
moved around unexpectedly.
So retain the section, but tag it as INFO, which tells the linker
that it should not be accounted for in the binary's memory layout.

According to UEFI spec:
Once an image is loaded, LoadImage() installs
EFI_HII_PACKAGE_LIST_PROTOCOL on the handle if the image contains a
custom PE/COFF resource with the type 'HII'. The protocol's
interface pointer points to the HII package list which is contained
in the resource's data.
This is controlled by the UEFI_HII_RESOURCE_SECTION define in the INF
file. When present the HII resource is linked with the module
binary.
Unfortunately GCC-built binaries have been stripping the .hii section
entirely. See "[edk2] HII gEfiHiiPackageListProtocolGuid problem

Up until SVN r18540, GenFw created invalid PE/COFF binaries for the ARM
architecture, by allowing PE/COFF .data sections to appear at offsets
that were not aligned to the global PE/COFF section alignment. The
reason for this was that the relocation metadata emitted by RVCT's
armlink only contains dynamic absolute relocations, so it is impossible
to recalculate relative relocations between .text and .data, and so the
relative offset between the two needs to be preserved.
Since r18540, we do align .data to the PE/COFF section alignment,
resulting in potentially corrupt PE/COFF binaries unless .data happens
to appear at a 32-byte aligned offset. So let's introduce a RVCT scatter
file that sets this alignment for the ELF .data section (and subsequent
.bss section).
At the same time, set the start offset to 0x220 bytes (which is the size
of our 32-bit PE/COFF header) so that the memory layouts are identical
between ELF and PE/COFF. Also add a 4 KB aligned version that can be
used to build DXE_RUNTIME_DRIVER modules with runtime memory protection
enabled.

The default behavior of the GCC compiler is to emit uninitialized globals
with external linkage into a COMMON section, where duplicate definitions
are merged. This may result in unexpected behavior, since global variables
defined under the same name in different C files may not refer to the same
logical data item.
For instance, the definitions of EFI_EVENT mVirtualAddressChangeEvent that
[used to] appear in the following files:
CryptoPkg/Library/BaseCryptLib/SysCall/RuntimeMemAllocation.c
MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c
will be folded into a single instance of the variable when the latter
module includes the former library, which can lead to unexpected results.
Even if some may argue that there are legal uses for COMMON allocation, the
high modularity of EDK2 combined with the low level of awareness of the
intracicies surrounding common allocation and the generally poor EDK2
developer discipline regarding the use of the STATIC keyword* make a strong
case for disabling it by default, and re-enabling it explicitly for packages
that depend on it.
So prevent GCC from emitting variables into the COMMON section, by passing
-fno-common to the compiler, and discarding the section in the GNU ld linker
script.
* Any function or variable that is only referenced from the translation unit
that defines it could be made STATIC. This does not only prevent issues
like the above, it also allows the compiler to generate better code, e.g.,
drop out of line function definitions after inlining all invocations or
perform constant propagation on variables.

This script can be used to check some expected rules for EDK II
patches. It only works on git formatted patches.
It checks both the commit message and the lines that are added in the
patch diff.
In the commit message it verifies line lengths, signature formats, and
the Contributed-under tag.
In the patch, it checks that line endings are CRLF for all files that
don't have a .sh extension. It verifies that no trailing whitespace is
present and that tab characters are not used.
Patch contributors should use this script prior to submitting their
patches. Package maintainers can also use it to verify incoming
patches.
It can also be run by specifying a git revision list, so actual patch
files are not always required.
For example, to checkout this last 5 patches in your git branch you
can run:
python PatchCheck.py HEAD~5..
Or, a shortcut (like git log):
python PatchCheck.py -5
The --oneline option works similar to git log --oneline.
The --silent option enables silent operation.
The script supports python 2.7 and python 3.

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.
