      Add sample crash console functions · 6c9ada31
      Antonio Nino Diaz authored 
      

Platforms that wish to use the sample functions have to add the file to
their Makefile. It is not included by default.

      plat/arm: Make crash console functions strong · c02c69f8
      Antonio Nino Diaz authored 
      

In Arm platforms the crash console doesn't print anything if the crash
happens early enough. This happens in all images, not only BL1. The
reason is that they the files ``plat/common/aarch64/platform_helpers.S``
and ``plat/arm/common/aarch64/arm_helpers.S``, and the crash console
functions are defined as weak in both files. In practice, the linker
can pick the one in ``plat/common``, which simply switches the multi
console to crash mode when it wants to initialize the crash console.
In the case of Arm platforms, there are no console drivers registered
at that point, so nothing is printed.

This patch makes the functions in plat/arm strong so that they override
the weak functions in plat/common.

      Add plat_crash_console_flush to platforms without it · 9c675b37
      Antonio Nino Diaz authored 
      

Even though at this point plat_crash_console_flush is optional, it will
stop being optional in a following patch.

The console driver of warp7 doesn't support flush, so the implementation
is a placeholder.

TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
they weren't global so they weren't actually used. Also, they were
calling the wrong functions.

imx8_helpers.S only has placeholders for all of the functions.

      zynqmp: Remove dependency on arm_helpers.S · bde25ae2
      Antonio Nino Diaz authored 
      

Non-Arm platforms shouldn't use Arm platform code. This patch copies the
implementation of the functions in arm_helpers.S to zynqmp_helpers.S to
remove this dependency of zynqmp on Arm platforms.
