CCA CoT uses 'core-swd-cert' for signing all secure software, so when
using cert_create tool to generate its certificate, it throws an
error: "tools/cert_create/cert_create: unrecognized option
'--tos-fw-key-cert'".
The issue has not been seen so far since "SPM+RME+TBB+Measured-Boot"
combination is not tested in CI/local-setup. It is now resolved by
guarding usage of '--tos-fw-key-cert' for non-CCA CoTs.

BL2_AT_EL3 is an overloaded macro which has two uses:
1. When BL2 is entry point into TF-A(no BL1)
2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).
BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

Platforms, which requires additional images to be
verified using TBBR; such that their key certificate
is tied to TRUSTED_KEY_CERT.
For such platforms, if make commands runs twice:
- Once with targets as bl2 & fip.bin, and
- Again to build the target as the additional image.
then, if path to the TRUSTED_KEY_CERT varies in the
makefile with make-target of the additional image, then
there would be two location where "trusted_key.crt" will
be created.
This patch helps overriding the TRUSTED_KEY_CERT from any .mk

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
The fiptool and cert_create use the same command options for images.
It is pretty easy to handle both in the same, symmetrical way.
Move CRT_ARGS and CRT_DEPS to FIP_ADD_PAYLOAD. This refactoring makes
sense because FIP_ADD_PAYLOAD is called from MAKE_BL (when building
images from source), and from FIP_ADD_IMG (when including external
images). (FIP_ADD_PAYLOAD will be renamed later on since it now
caters to both fiptool and cert_create).
We can delete CERT_ADD_CMD_OPT for images in tbbr.mk. It still
needs to call CERT_ADD_CMD_OPT directly for certificates.

The build system supports generating two FIP images, fip and fwu_fip.
Accordingly, we have similar build macros.
FIP_ADD_PAYLOAD <--> FWU_FIP_ADD_PAYLOAD
CERT_ADD_CMD_OPT <--> FWU_CERT_ADD_CMD_OPT
FIP_ADD_IMG <--> FWU_FIP_ADD_IMG
The duplicated code increases the maintenance burden. Also, the build
rule of BL2U looks clumsy - we want to call MAKE_BL to compile it from
source files, but we want to put it in fwu_fip. We can not do it in a
single macro call since the current MAKE_BL does not support fwu_fip.
To refactor those in a clean way is to support one more argument to
specify the FIP prefix. If it is empty, the images are targeted to
fip, whereas if the argument is "FWU_", targeted to fwu_fip.
The build macros prefixed with FWU_ go away.

It is better to not include BL2 in FIP when using `BL2 at EL3` as
platforms using this config would not have the capability to parse the

This patch fixes a couple of issues for AArch32 builds on ARM reference
platforms :
1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
the BL31 memory is empty when built for AArch32. Hence this patch allocates
BL32 to the memory region occupied by BL31 for AArch32 builds.
As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
be used to control the load address of BL32 in AArch32 mode which was
never the intention of the macro anyway.
2. A static assert is added to sp_min linker script to check that the progbits
are within the bounds expected when overlaid with other images.
3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
involved when building Juno for AArch32 mode, the build option SPD needed to
specifed. This patch corrects this and also updates the documentation in the
user-guide.
4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
a result the previous assumption that BL31 must be always present is removed
and the certificates for BL31 is only generated if `NEED_BL31` is defined.

fiptool provides a more consistent and intuitive interface compared to
the fip_create program. It serves as a better base to build on more
features in the future.
fiptool supports various subcommands. Below are the currently
supported subcommands:
1) info - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file. This is a new command that
was not present in fip_create.
To create a new FIP file, replace "fip_create" with "fiptool create".
To update a FIP file, replace "fip_create" with "fiptool update".
To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".
A compatibility script that emulates the basic functionality of
fip_create is provided. Existing scripts might or might not work with
the compatibility script. Users are strongly encouraged to migrate to
fiptool.

If an SPD wants to use a prebuilt binary as BL32 image (for example,
the OPTEE Dispatcher), it must point the `BL32` variable to the
image file. This dependency should apply only to the `fip` target.
However, it also applies to the `all` target at the moment. If the
user tries to build all individual TF images using `make all`
without setting BL32, the build fails. The following command will
throw the error:
make CROSS_COMPILE=aarch64-linux-gnu- SPD=opteed all
...
...
aarch64-linux-gnu-gcc: fatal error: no input files
compilation terminated.
make: *** [build/fvp/release/bl32/bl32.ld] Error 1
The reason is that the build system checks if BL32 is defined, and
if it is not, it will try to build BL32 from source. If the SPD
makefile does not provide support for that (as is the case of the
OPTEE Dispatcher, since OPTEE is provided as an external binary),
the build will fail.
This patch fixes the issue by checking if `BL32_SOURCES` has been
defined by the SPD before attempting to build BL32 from source.
If neither `BL32` nor `BL32_SOURCES` is defined when building the
FIP, a warning message will be printed and the process aborted.

This patch is a complete rework of the main Makefile. Functionality
remains the same but the code has been reorganized in sections in
order to improve readability and facilitate adding future extensions.
A new file 'build_macros.mk' has been created and will contain common
definitions (variables, macros, etc) that may be used from the main
Makefile and other platform specific makefiles.
A new macro 'FIP_ADD_IMG' has been introduced and it will allow the
platform to specify binary images and the necessary checks for a
successful build. Platforms that require a BL30 image no longer need
to specify the NEED_BL30 option. The main Makefile is now completely
unaware of additional images not built as part of Trusted Firmware,
like BL30. It is the platform responsibility to specify images using
the macro 'FIP_ADD_IMG'. Juno uses this macro to include the BL30
image in the build.
BL33 image is specified in the main Makefile to preserve backward
compatibility with the NEED_BL33 option. Otherwise, platform ports
that rely on the definition of NEED_BL33 might break.
All Trusted Board Boot related definitions have been moved to a
separate file 'tbbr_tools.mk'. The main Makefile will include this
file unless the platform indicates otherwise by setting the variable
'INCLUDE_TBBR_MK := 0' in the corresponding platform.mk file. This
will keep backward compatibility but ideally each platform should
include the corresponding TBB .mk file in platform.mk.
