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.

Add support for default stack-protector flag ...

The current stack-protector support is for none, "strong" or "all".
The default use of the flag enables the stack-protection to all
functions that declare a character array of eight bytes or more in
length on their stack.
This option can be tuned with the --param=ssp-buffer-size=N option.

ti: k3: common: Remove MSMC port definitions ...

The MSMC port defines were added to help in the case when some ports
are not connected and have no cores attached. We can get the same
functionality by defined the number of cores on that port to zero.
This simplifies several code paths, do this here.

rockchip: only include libfdt in non-coreboot cases ...

While mainline u-boot always expects to submit the devicetree
as platform param, coreboot always uses the existing parameter
structure. As libfdt is somewhat big, it makes sense to limit
its inclusion to where necessary and thus only to non-coreboot
builds.

libfdt itself will get build in all cases, but only the non-
coreboot build will actually reference and thus include it.

docs: plat: stm32mp1: Document the usage of DTB_FILE_NAME variable ...

Since STM32MP1 platform supports different boards, it is necessary
to build for a particular board. With the current instructions, the
user has to modify the DTB_FILE_NAME variable in platform.mk for
building for a particular board, but this can be avoided by passing
the appropriate board DTB name via DTB_FILE_NAME make variable.
Hence document the same in platform doc.
