For Denver CPUs, this approach enables the mitigation during EL3
initialization, following every PE reset. No mechanism is provided to
disable the mitigation at runtime.
This approach permanently mitigates the EL3 software stack only. Other
software components are responsible to enable it for their exception
levels.
TF-A implements this approach for the Denver CPUs with DENVER_MIDR_PN3
and earlier:
* By setting bit 11 (Disable speculative store buffering) of
`ACTLR_EL3`
* By setting bit 9 (Disable speculative memory disambiguation) of
`ACTLR_EL3`
TF-A implements this approach for the Denver CPUs with DENVER_MIDR_PN4
and later:
* By setting bit 18 (Disable speculative store buffering) of
`ACTLR_EL3`
* By setting bit 17 (Disable speculative memory disambiguation) of
`ACTLR_EL3`

Denver CPUs expect the power state field to be reset to 'C1'
during boot. This patch updates the reset handler to reset the
ACTLR_.PMSTATE field to 'C1' state during CPU boot.

The current functions to disable and enable Dynamic Code Optimizer
(DCO) assume that all denver cores are in the same cluster. They
ignore AFF1 field of the mpidr_el1 register, which leads to
incorect logical core id calculation.
This patch calls the platform handler, plat_my_core_pos(), to get
the logical core id to disable/enable DCO for the core.

Similar files can be generated using openssl or mbedtls.

This patch enables handling PMU overflow IRQ by GIC SPI's
directly in EL3. Also implement additional SMC routine,
which can disable the solution on demand in runtime.
Since it is possible to configure PMU interrupt trigger type
in the MADT ACPI table, it is enough to set it only once in EL3
during initialization.

This patch introduces new helper routines that allow
configuring the individual IRQs to be edge/level-triggered
via GICD_ICFGR registers. This is helpful to modify
the default configuration of the non-secure GIC SPI's, which
are all set during initialization to be level-sensitive.

In order to allow the use of PCIe cards such as graphics cards, whose
demands for BAR space are typically much higher than those of network
or SATA/USB cards, reconfigure the I/O windows so we can declare two
MMIO PCI regions: a 512 MB MMIO32 one at 0xc000_0000 and a 4 GB MMIO64
one at 0x8_0000_0000. In addition, this will leave ample room for an
ECAM config space at 0xe000_0000 (up to the ECAM maximum of 256 MB)
For compatibility with older kernels or firmware, leave the original
16 MB window in place as well.
