Mark Rutland d855b261d1 ArmPkg/ArmPlatformPkg: position vectors relative to base
We currently rely on .align directives to ensure that each exception
vector entry is the appropriate offset from the vector base address.

This is slightly fragile, as were an entry to become too large (greater
than 32 A64 instructions), all following entries would be silently
shifted until they meet the next alignment boundary. Thus we might
execute the wrong code in response to an exception.

To prevent this, introduce a new macro, VECTOR_ENTRY, that uses .org
directives to position each entry at the precise required offset from
the base of a vector. A vector entry which is too large will trigger a
build failure rather than a runtime failure which is difficult to debug.

For consistency, the base and end of each vector is similarly annotated,
with VECTOR_BASE and VECTOR_END, which provide the necessary alignment
and symbol exports. The now redundant directives and labels are removed.

Ard Biesheuvel 19bb46c411 ArmVExpressPkg/ArmVExpressLibRTSM: map NOR flash as normal memory
Some users of this library (i.e., FVP-AArch64 and RTSM-A15_MPCore)
may be built to execute straight from NOR flash. Since device mappings
should have the XN attribute set (according to the architecture), mapping
the NOR flash as a device may prevent it from being executable.

Since the NOR flash DXE driver is perfectly capable of setting the correct
attributes for the region it needs to write to, and since we will be
executing from DRAM by that time anyway, we can simply map the NOR flash
as normal memory initially.

Ard Biesheuvel 0ce8410ed7 ArmPlatformPkg: bring DS-5 scripts in line with linker script changes
The ARM and AARCH64 linker scripts have recently been updated so that
the memory layouts of the ELF and PE/COFF versions of each module are
identical. In particular, this means that the ELF images now have a
hole before the first section rather than starting at offset 0x0, which
means we no longer have to correct for this difference when loading the
ELF image into the debugger.

Jeremy Linton efcc052bdf ArmPlatformPkg: Juno - add correct SPI interrupt numbers for MSI
The JunoR1 has a GICv2m which is a GICv2 with a little piece of hardware
that has some memory mapped locations that can trigger traditional SPI
interrupts. This allows some basic PCIe MSI capabilities.

Setup the SPI range that is mapped by the MSI window. This range is
described in the JunoR1 SoC TRM, table 3-3. Under Interrupt ID 244-351 is
described as "GICv2m PCI Express MSI". In the future when these tables
are generated programmatically the information may be found in the
MSI_TYPER register as well.

Jeremy Linton 368002a31c Update the ACPI device information for ARM Juno.
These patches correct a number of problems with the JUNO ACPI tables.

First, put CCA attributes on the devices which can do DMA. This is
because the linux kernel now requires ARM64 devices specify a coherency
model. Without CCA the devices are unable to perform DMA.

Update the EHCI window to a full 64k as documented in the
Juno Platform SoC TRM. This makes it match the values used in some
other places.

Finally, add some _DSD entries for the SMSC ethernet chip.
The latter changes are required for the mainline kernels to use the adapter.

Laszlo Ersek 582085eb1f ArmPlatformPkg: NorFlashDxe: mellow DEBUG messages about flash reinit
The ValidateFvHeader() function checks several conditions against the
firmware volume header. Failure of the first of these checks, reported as
"No Firmware Volume header present", is a common situation for unformatted
flash images, especially when a new virtual machine is created.

Similarly, "Variable Store Guid non-compatible" is common when the
firmware binary is switched from Secure Boot-incapable to Secure
Boot-capable, or vice versa.

The only caller of ValidateFvHeader(), NorFlashFvbInitialize(), handles
all these mismatches by installing a new FVB header. It also emits
another, loud ERROR message (which is even less justified when it is
triggered by (BootMode == BOOT_WITH_DEFAULT_SETTINGS)).

Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they
don't clutter the debug output when the PcdDebugPrintErrorLevel mask only
enables EFI_D_ERROR (i.e., in a "silent" build).

These messages have annoyed / confused users; see for example:

Ard Biesheuvel 0f060e34a4 ArmPlatformPkg: signal EndOfDxe event in PlatformBsdInit
Like the ArmVirtPkg platforms up until SVN r17713, the ArmPlatformPkg
platforms built with the Intel BDS fail to signal the end-of-DXE event
'gEfiEndOfDxeEventGroupGuid' when entering the BDS phase, which results
in some loss of functionality, i.e., variable reclaim in the VariableDxe
drivers, and the splitting of the memory regions that is part of the recently
added UEFI 2.5 properties table feature.

As discussed on the edk2-devel mailing list here:

http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109

it is up to the platform BDS to signal that event, since there may be
platform specific ordering constraints with respect to the signalling
of the event that are difficult to honor at the generic level.

So add the SignalEvent () call to PlatformBdsInit () of ArmPlatformPkg's
PlatformBdsLib implementation for the Intel BDS.

Ard Biesheuvel 9bdf791f7d ArmPlatformPkg/ArmJunoPkg: use a rodata symbol for ReferenceAcpiTable
The ACPI .aslc files contain a ReferenceAcpiTable() function whose
sole purpose is to ensure that the table itself does not get optimized
away. However, when using clang, these dummy functions result in a 4 KB
section alignment requirement, which is silly since everything except
the .data section is discarded later anyway.

So instead, make ReferenceAcpiTable a CONST pointer to VOID*. This way,
we still have a .text section, which is mandatory for the PE/COFF
conversion, but no executable code with small model relocations that
impose additional alignment requirements.

Ard Biesheuvel 0c7cc4fb92 ArmPlatformPkg/PrePeiCore: constify PPI globals
Since PrePeiCore's .text section contains an AARCH64 exception
vector table, its 2 KB alignment propagates to other sections as
well. Since this is a SEC module, it should not have any writable
data in the first place, so change some non-const PPI globals to
const. The resulting binary has no .data section at all, which
saves 2 KB in the XIP image.

Ard Biesheuvel 8d13298b80 ArmPkg: split off ArmGicArchLib from ArmGicLib
The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.

However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.

In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.
