Ard Biesheuvel 6ea34e3a45 ArmPkg: remove cache maintenance by VA operation range size threshold
This removes the range size threshold for virtual address based cache
maintenance instructions that operate on VA ranges to be 'promoted' to
use set/way instructions.

Doing so is unsafe: set/way operations are fundamentally different
from VA operations, and really only suitable for cleaning or invalidating
a cache when turning it on or off.

To quote the ARM ARM (DDI0487A_d G3.4):
"""
Since the set/way instructions are performed only locally, there is no
guarantee of the atomicity of cache maintenance between different PEs,
even if those different PEs are each performing the same cache maintenance
instructions at the same time. Since any cacheable line can be allocated
into the cache at any time, it is possible for [a] cache line to migrate
from an entry in the cache of one PE to the cache of a different PE in a
manner that the cache line avoids being affected by set/way based cache
maintenance. Therefore, ARM strongly discourages the use of set/way
instructions to manage coherency in coherent systems.

Ard Biesheuvel 523b5266b7 ArmPkg: allow patchable PCDs for memory, FD and FV addresses
In order to allow a runtime self relocating PrePi instance, change the
allowable PCD types for the following PCDs:

  gArmTokenSpaceGuid.PcdSystemMemoryBase
  gArmTokenSpaceGuid.PcdSystemMemorySize
  gArmTokenSpaceGuid.PcdFdBaseAddress
  gArmTokenSpaceGuid.PcdFvBaseAddress

to include PcdsPatchableInModule. This makes the build system correctly
distinguish fixed PCDs from PCDs whose value may be different from the
assigned value at compile time.

Note that this only affects platforms that explicitly mark these PCDs as
PatchableInModule in the DSC. All existing platforms that use FixedPcd
will not be affected by this change.

The DT binding for the ARM generic timer describes the secure,

However, under virtualization, only the virtual timer is usable, and
the device tree may omit the hypervisor timer interrupt. (Other timer
interrupts cannot be omitted simply due to the fact that the virtual
timer is listed third)

Ronald Cron daefd574f9 ArmPkg/SemihostFs: Implement SetInfo() and handle seeking past the end of a file
Implement the resizing of the file with SetInfo().
Implement the renaming of a file with SetInfo().
Allow to seek past the end of a file.

The support of file resizing implies a rework of the read, write
and close functions. So does the support of seeking past the end
of a file. That why those two changes are done in the same patch.

Ronald Cron c20f8ec661 ArmPkg/Semihostlib: Rename semi-hosting open option
Change mnemonic SEMIHOST_FILE_MODE_CREATE with mnemonic SEMIHOST_FILE_MODE_UPDATE.
The bit referred to by this mnemonic is for the semi-hosting open mode code the
equivalent of the + in the ISO C fopen mode terminology. This allows to select the
so called update mode for which both read and write are allowed on the open file.
The mnemonic SEMIHOST_FILE_MODE_UPDATE is more in line with the ISO C fopen mode
terminology. A description of the ISO C fopen modes can be found here :

Prior to this change, when a new page table was created at level N+1,
the reference to the table was added to the level N translation table,
before being initialized.
It means if virtual addresses were in the address range defined by
this new table the CPU would crash as the address range was not
initialized.

Ard Biesheuvel b1a633434d ArmPkg/TimerDxe: add workaround for KVM timer interrupt handling
KVM on ARM currently masks the timer interrupt on the timer side when
delivering an interrupt to the guest. This itself is a workaround for an
issue where the interrupt is reraised and trapped by the host as soon as
the guest is entered, resulting in the guest being starved.

Work around this by calling ArmGenericTimerEnable () after servicing each
interrupt. The virtual version of ArmGenericTimerCounterLib will then
make sure to unmask the interrupt again.

Ard Biesheuvel 7a1e861e29 ArmPkg/TimerDxe: Read timer frequency from CPU
The PCD gArmTokenSpaceGuid.PcdArmArchTimerFreqInHz is used in the
SEC phase (if applicable) to write the platform's counter frequency
to the CNTFRQ system register, as this needs to be done by the highest
exception level implemented.

Under virtualization, we should be able to rely on the host to have
initialized this register to a sane value, as we run at EL1 and only
use the virtual timer, so the PcdArmArchTimerFreqInHz PCD has little
meaning here.

So in either case, by the time we enter the DXE phase, we can use the
CNTFRQ system register to read the frequency instead of looking at the
PCD.
