And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

If the CPU doesn't run from BL31_BASE, the firmware needs to be
copied from load address to BL31_BASE during cold boot. The size
should be the actual size of the code, which is indicated by the
__RELA_END__ linker variable.

This patch updates the copy routine to use this variable as a
result.

The delay_timer driver for Tegra uses the CNTPS_TVAL_EL1 secure, physical,

The Memory Controller provides a control register to check

might have locked this feature, which will be reflected by
this register.

This patch reads the control register before processing
a video memory resize request. An error code, -ENOTSUP,
is returned if the feature is locked.

The previous sequence used by the driver to program the new memory
aperture settings and clear the non-overlapping memory was faulty.
The sequence locked the non-overlapping regions twice, leading to
faults when trying to clear it.

This patch modifies the sequence to follow these steps:

* move the previous memory region to a new firewall register
* program the new memory aperture settings
* clean the non-overlapping memory

This patch also maps the non-overlapping memory as Device memory to
follow guidance from the arch. team.
