cpus: denver: Implement static workaround for CVE-2018-3639
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

* By setting bit 18 (Disable speculative store buffering) of

* By setting bit 17 (Disable speculative memory disambiguation) of
`ACTLR_EL3`

- Defines clock identifiers
An array of clock gates is provided in the CCM block. In order to index

Section 5.2.5 of the i.MX7 Solo Application Processor Reference Manual
Rev 0.1 provides the relevant details.

This is a comprehensive definition of the target clock mux select bits.
These bits are required to correctly select the clock source. Defining

which differ from the clock-gate indices.
- Provides a clock gate enable/disable routine
Provides a clock-gate enable/disable routine via the set/clr
registers in a given clock-gate control register block.
This index passed should be one of the enums associated with CCM and

Prepare Mbed TLS drivers for shared heap
The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.
Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform

drivers: imx: uart: Add mxc_console
- Adds a simple register read/write abstraction to cut-down on the
amount of typing and text required to access UART registers in this driver.
- Adds a console getc() callback.
- Adds a console putc() callback, translating '\n' to '\r' + '\n'.
- Initializes the MXC UART, take a crude method of calculating the
BAUD rate generator. The UART clock-gates must have been enabled prior
to launching the UART init code.
Special care needs to be taken to ensure the UBIR is initialized before the
UBMR and we need to ensure that UCR2.SRST comes good before trying to
program other registers associated with the UART.
