In AArch32, execution of 2 instructions with opposite condition code
might lead to either a data corruption or a CPU deadlock. Set the bit
12 of the Diagnostic Register to prevent this.

Broadcast maintainance operations might not be correctly synchronized
between cores. Set bit 7 of S3_0_C15_C0_2 to prevent this.

There are some incorrect casts and some missing casts in the headers.
This patch fixes the ones that were 64-bit or 32-bit wide wrongly and
adds casts where they were missing.

Note that none of the changes of the patch actually changes the values
of the definitions. This patch is just for correctness.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

For affected 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 entire software stack and no
additional mitigation code is required in other software components.

TF-A implements this approach for the following affected CPUs:

*   Cortex-A57 and Cortex-A72, by setting bit 55 (Disable load pass store) of
    `CPUACTLR_EL1` (`S3_1_C15_C2_0`).

*   Cortex-A73, by setting bit 3 of `S3_0_C15_C0_0` (not documented in the
    Technical Reference Manual (TRM)).

*   Cortex-A75, by setting bit 35 (reserved in TRM) of `CPUACTLR_EL1`
    (`S3_0_C15_C1_0`).

Additionally, a new SMC interface is implemented to allow software
executing in lower ELs to discover whether the system is mitigated
against CVE-2018-3639.

This patch adds cpumerrsr_el1 and l2merrsr_el1 to the register dump on
error for applicable CPUs.

These registers hold the ECC errors on L1 and L2 caches.

This patch updates the A53, A57, A72, A73 (l2merrsr_el1 only) CPU libraries.

This patch adds ARM Cortex-A73 MPCore Processor support
in the CPU specific operations framework. It also includes
this support for the Base FVP port.
