Adding an 'all' rule prevents a rule included from scripts/*.mk becoming
the default rule if nothing is specified on the make command line.

Since u-boot.bin is passed as $(BL33) in the TFA build, both 'all' and
'tfa' should depend on u-boot.bin getting built first.

ifeq/ifneq is more robust than ifdef because ifdef doesn't handle set

This tool isn't using $(TARGET) anymore to choose the build platform.
The build configuration is entirely determined by the U-Boot
configuration. Now to use the tool, run "make <target>_defconfig" where
<target> is the name of a file in the u-boot/configs directory.

All platform specific configuration is moved out into separate files so
that the main makefile only contains common code. Choose which files to
include based on the values of u-boot configuration variables. Currently
these four U-Boot variables are used:
   CONFIG_SYS_VENDOR ==> include scripts/vendor-$(CONFIG_SYS_VENDOR).mk
   CONFIG_SYS_SOC ==> include scripts/soc-$(CONFIG_SYS_SOC).mk
   CONFIG_SYS_BOARD ==> include scripts/board-$(CONFIG_SYS_BOARD).mk
   CONFIG_SYS_CONFIG_NAME ==> include scripts/config-$(CONFIG_SYS_CONFIG_NAME).mk

This patch adopts the Linux & U-boot kbuild style top level Makefile
that includes the generated config so that decisions can be made from
the specific config. The core of this change is to pull in the %config
parsing rules for u-boot/Makefile and process them separately from the
main build rules. This allows *config rules to change the U-Boot
configuration, and the import the CONFIG_* values into make so that
TFA_PLAT and other variables can be automatically determined.

Instead of setting the build directory unconditionally (which doesn't
entirely work anyway; U-Boot handles it well, but TFA and DT-rebasing do
not), by default let each project use it's own working directory.
However, if BUILD_BASE is set, then use that to create build directories
for the projects that support it.

Adds an esp.img target for creating an ESP filesystem with the UEFI
shell on the SD card image. The ESP is first created by copying the
wanted files into the esp.tree directory, and then using mtools to put
the files into a fat filesystem image.

Set up a recursive structure so that u-boot defconfig can be run first
and then included in the 2nd stage makefile.

Signed-off-by: Grant Likely <grant.likely@arm.com>

U-Boot defconfig already knows a lot about the platform. Use the
defconfig data to know what the SoC is and start with sane defaults.

This currently works by running the U-Boot defconfig step with a
:=$(shell) statement before executing any make rules. It is a little
ugly to do it this way, and it may be better to recursively call Make
so that the output of make <target>_defconfig is executed in a proper
rule.

The old name, 'u-boot-manifest', isn't autocomplete friendly. Renaming

This is a *terrible* hack, but it gets a target added for flashing the
firmware to an SD. What is needed is a way to abstract platform specific
flash targets so that each target can do what it needs.

In the case of the rk3399 platforms, it would be best to create a GPT on
the SD card with a couple of protected partitions for the firmware
images. I'll look into doing that later.

Splitting the individual platforms into separate makefiles simplifies
the build scripts considerably. The Makefile now includes a
platform-specific makefile based on the value of ${TARGET}, and the
included file can override the variables as needed for the
configuration.
