drivers: ufs: Extend the delay after reset to wait for some slower chips ...

We've seen issues with some THG based UFS chips, where
after reset the LUNs don't always enumerate properly.

After some debugging, we found that extending the mdelay
here seems to resolve the issue by giving the chips enough
time to complete reset.

Merge "Add compile-time errors for HW_ASSISTED_COHERENCY flag" into integration

Add compile-time errors for HW_ASSISTED_COHERENCY flag ...

This patch fixes this issue:
https://github.com/ARM-software/tf-issues/issues/660

The introduced changes are the following:

1) Some cores implement cache coherency maintenance operation on the
hardware level. For those cores, such as - but not only - the DynamIQ
cores, it is mandatory that TF-A is compiled with the
HW_ASSISTED_COHERENCY flag. If not, the core behaviour at runtime is
unpredictable. To prevent this, compile time checks have been added and
compilation errors are generated, if needed.

2) To enable this change for FVP, a logical separation has been done for
the core libraries. A system cannot contain cores of both groups, i.e.
cores that manage coherency on hardware and cores that don't do it. As
such, depending on the HW_ASSISTED_COHERENCY flag, FVP includes the
libraries only of the relevant cores.

3) The neoverse_e1.S file has been added to the FVP sources.

rockchip: Disable binary generation for all SoCs. ...

All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
have non-continuous memory areas in the linker script with a huge
gap between them. This results in extremely padded binary images
with a size of about 4 GiB.

E.g. on the RK3399 we have the following memory areas (and base addresses):
RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).

Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
use the ELF image instead, which has a size of a few hundred kBs.

In order to prevent the generation of a huge and useless file,
this patch disables the binary generation for all affected Rockchip
SoCs.

build_macros: Add mechanism to prevent bin generation. ...

On certain platforms it does not make sense to generate
TF-A binary images. For example a platform could make use of serveral
memory areas, which are non-continuous and the resulting binary
therefore would suffer from the padding-bytes.
Typically these platforms use the ELF image.

This patch introduces a variable DISABLE_BIN_GENERATION, which
can be set to '1' in the platform makefile to prevent the binary
generation.

rockchip: Allow console device to be set by DTB. ...

Currently the compile-time constant PLAT_RK_UART_BASE defines
which UART is used as console device. E.g. on RK3399 it is set
to UART2. That means, that a single bl31 image can not be used
for two boards, which just differ on the UART console.

This patch addresses this limitation by parsing the "stdout-path"
property from the "chosen" node in the DTB. The expected property
string is expected to have the form "serialN:XXX", with
N being either 0, 1, 2, 3 or 4. When the property is found, it will
be used to override PLAT_RK_UART_BASE.

Tested on RK3399-Q7, with a stdout-path of "serial0:115200n8".

rockchip: Add params_setup to RK3328. ...

params_setup.c provides the function params_early_setup, which
takes care of parsing ATF parameters (bl31_plat_param array,
fdt or coreboot table). As params_early_setup is defined as weak
symbol in bl31_plat_setup.c, providing a platform-specific
bl31_plat_setup implementation is optional.

This patch adds the rockchip-common params_setup.c to the sources
for RK3328. This streamlines the parameter handling for all supported
rockchip SoCs.

rockchip: Streamline and complete UARTn_BASE macros. ...

In order to set the UART base during bootup in common code of
plat/rockchip, we need to streamline the way the UART base addresses
are defined and add the missing definitions and mappings.

This patch does so by following the pattern UARTn_BASE, which is
already in use on RK3399 and RK3328. The numbering itself is derived
from the upstream Linux DTS files of the individual SoCs.
