Laszlo Ersek 11ceb258f3 ArmPkg: convert LFs to CRLF, expand hard TABs
We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

At the same time, the following three files had to undergo TAB expansion:

  ArmPkg/Library/ArmSoftFloatLib/ArmSoftFloatLib.c
  ArmPkg/Library/GccLto/liblto-aarch64.s
  ArmPkg/Library/GccLto/liblto-arm.s

I used "expand -t 2", in order to stay close to the edk2 coding style
(which uses two spaces for indentation.)

Both the CRLF conversion and the TAB expansion are motivated by
"PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion
and TAB expansion have to happen in the same patch.

In commit 1fce963d89 we reduced the level of information printed

PeCoffLoaderUnloadImageExtraAction() prints helpful debugger commands

EFI_D_ERROR level; they don't report errors. Change the debug level
(bitmask, actually) to DEBUG_LOAD | DEBUG_INFO, because the messages are
printed in relation to image loading, and they are informative.

Ard Biesheuvel 371e7001e8 ArmPkg/ArmSoftFloatLib GCC4x: fix build failure
The upstream SoftFloat code that was recently incorporated into
ArmSoftFloatLib uses some parameterization to tweak the inlining
and optimization behavior for different compilers.

The custom platform.h file that sets these parameters is based on
the upstream version for Linux/ARM, but was updated to include the
'always_inline' GCC attribute into the INLINE macro, to ensure that
all definitions that are marked as inline are not only inlined into
their callers, but also to ensure that no version of the function is
ever emitted into the object file.

This works fine on recent GCC and Clang, but the latter part turns
out to break on GCC 4.x, resulting duplicate definition linker errors.
Fortunately, the synticatically more appriopriate 'static inline'
works fine on both the recent and the older compilers, so let's switch
to that instead.

Ard Biesheuvel 3cc57695df ArmPkg/ArmSoftFloatLib: switch to new version of softfloat library
Update the INF description and the top level .c files in order to
switch to the new version of the SoftFloat library imported as a
Git submodule in the previous patch.

Note that we no longer use the code that travelled a long way from
the 2002 version of the softfloat library via NetBsd and the StdLib
package. Instead, we are using the upstream version unmodified, with
the glue .c file adopted from the OP-TEE project. This approach is
much cleaner and much more maintainable.

Note that support for the RVCT toolchains is being dropped at the same
time. RVCT is mostly untested, and planned to be removed, and so it
makes little sense to go to the trouble of upgrading this library for
RVCT as well.

Ard Biesheuvel d5788777bc ArmPkg/ArmMmuLib AARCH64: get rid of needless TLB invalidation
Currently, we always invalidate the TLBs entirely after making
any modification to the page tables. Now that we have introduced
strict memory permissions in quite a number of places, such
modifications occur much more often, and it is better for performance
to flush only those TLB entries that are actually affected by
the changes.

At the same time, relax some system wide data synchronization barriers
to non-shared. When running in UEFI, we don't share virtual address
translations with other masters, unless we are running under virt, but
in that case, the host will upgrade them as appropriate (by setting
an override at EL2)

core, or the CPU DXE driver when running under PrePi.

Since exceptions are not actually handled at all on AArch64, and simply
routed to the DefaultExceptionHandlerLib (for which a special version
has been created to be usable this early), let's get rid of this
dubious functionality altogether.

Ard Biesheuvel aa1097921d ArmPkg/ArmMmuLib ARM: handle unmapped sections when updating permissions
The ARM ArmMmuLib code currently does not take into account that
setting permissions on a region should take into account that a
region may not be mapped yet to begin with.

So when updating a section descriptor whose old value is zero,
pass in the address explicitly.

Ard Biesheuvel e36b243c71 ArmPkg/ArmMmuLib: take the CPU supported maximum PA space into account
In preparation of dropping PcdPrePiCpuMemorySize entirely, base the
maximum size of the identity map on the capabilities of the CPU.
Since that may exceed what is architecturally permitted when using
4 KB pages, take MAX_ADDRESS into account as well.

Achin Gupta eed947be0b ArmPkg/ArmMmuLib: Add MMU Library suitable for use in S-EL0.
The Standalone MM environment runs in S-EL0 in AArch64 on ARM Standard
Platforms. Privileged firmware e.g. ARM Trusted Firmware sets up its
architectural context including the initial translation tables for the
S-EL1/EL0 translation regime. The MM environment will still request ARM
TF to change the memory attributes of memory regions during
initialization.

The Standalone MM image is a FV that encapsulates the MM foundation
and drivers. These are PE-COFF images with data and text segments.
To initialise the MM environment, Arm Trusted Firmware has to create
translation tables with sane default attributes for the memory
occupied by the FV. This library sends SVCs to ARM Trusted Firmware
to request memory permissions change for data and text segments.

This patch adds a simple MMU library suitable for execution in S-EL0 and
requesting memory permissions change operations from Arm Trusted Firmware.

Ard Biesheuvel 6556224e1f ArmPkg/ArmSmcPsciResetSystemLib: add missing call to ExitBootServices()
Our poor man's implementation of EnterS3WithImmediateWake () currently
sets a high TPL level to disable interrupts, and simply calls the
PEI entrypoint again after disabling the MMU.

Unfortunately, this is not sufficient: DMA capable devices such as
network controllers or USB controllers may still be enabled and
writing to memory, e.g., in response to incoming network packets.

So instead, do the full ExitBootServices() dance: allocate space and
get the memory map, call ExitBootServices(), and in case it fails, get
the memory map again and call ExitBootServices() again. This ensures
that all cleanup related to DMA capable devices is performed before
doing the warm reset.

writeback cacheable so ASSERT() that this is the case.
