Juno: Change the Firmware update detect mechanism
...
Previously, Juno used to depend on the SSC_GPRETN register to inform
about the reset syndrome. This method was removed when SCP migrated
to the SDS framework. But even the SDS framework doesn't report the
reset syndrome correctly and hence Juno failed to enter Firmware
update mode if BL2 authentication failed.
In addition to that, the error code populated in V2M_SYS_NVFLAGS register
does not seem to be retained any more on Juno across resets. This could
be down to the motherboard firmware not doing the necessary to preserve
the value.
Hence this patch modifies the Juno platform to use the same mechanism to
trigger firmware update as FVP which is to corrupt the FIP TOC on
authentication failure. The implementation in `fvp_err.c` is made common
for ARM platforms and is moved to the new `arm_err.c` file in
plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
are modified to allow write to the Flash memory address.

BL2U: Fix ARM platform timer initilization
...
This issue was detected when testing FWU on Juno. The Timer
`timer_ops` was not being initialized before being used by
the SDS driver on Juno. This patch adds the call to
`generic_delay_timer_init()` during bl2u_early_platform_setup().
This is done generically for all ARM platforms because the
cost involved is minimal.

Remove sp_min functions from plat_common.c
...
This patch removes default platform implementations of sp_min
platform APIs from plat/common/aarch32/plat_common.c. The APIs
are now implemented in `plat_sp_min_common.c` file within the
same folder.
The ARM platform layer had a weak definition of sp_min_platform_setup2()
which conflicted with the weak definition in the common file. Hence this
patch fixes that by introducing a `plat_arm_` version of the API thus
allowing individual boards within ARM platforms to override it if they
wish to.
Fixes ARM-software/tf-issues#559

Fix FVP DRAM2 size

This was correct according to the model specifications , but it seems
that FVP doesn't implement it. It is safer to use the size exposed by

FVP: Allow building for DynamIQ systems
...
FVPs that model DynamIQ configuration implements all CPUs in a single
cluster. I.e., such models have a single cluster with more than 4 CPUs.
This differs from existing default build configuration for FVP where up
to 4 CPUs are assumed per cluster.
To allow building for DynamIQ configuration, promote the macro
FVP_MAX_CPUS_PER_CLUSTER as a build option to have it set from the build
command line. The value of the build option defaults to 4.

FVP: Add TB_FW_CONFIG and HW_CONFIG

This patch adds TB_FW_CONFIG for FVP and allows FVP
to select the appropriate HW_CONFIG to include in the
fip. The HW_CONFIG for FVP is selected via `FVP_HW_CONFIG_DTS`
build option. The TB_FW_CONFIG specifies the load address of
HW_CONFIG to BL2. Since currently the load address is different
between AARCH32 and AARCH64, 2 separate TB_FW_CONFIGs are
maintained for the 2 modes.

ARM Platforms: Load HW_CONFIG in BL2
...
The patch adds the necessary changes to load HW_CONFIG in BL2 for
ARM Platforms :
1. The load address of HW_CONFIG is specified via the `hw_config_addr`
property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
property defines the maximum size to be expected for the HW_CONFIG.
The `arm_dyn_cfg_helpers.c` and corresponding header implements
utility functions to parse these DT properties defined.
The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
them to be invoked from ARM platform layer.
2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
the list of images to be loaded by BL2.
3. The `libfdt` sources are now included when BL2 is built
4. A new helper `populate_next_bl_params_config()` is introduced in
desc_image_load.c to populate the subsequent executable BL images
with the `hw_config` and the corresponding `fw_config` if available.
The `plat_get_next_bl_params()` API for ARM platforms is modified to
invoke this new helper.
5. The implementation of `bl2_early_platform_setup2()` is modified to
consider `arg0` as well in addition to `arg1` passed from BL1.
6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.

Build: change the first parameter of TOOL_ADD_IMG to lowercase
...
In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.
Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.
make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist. We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.

Build: merge build macros between FIP_ and FWU_FIP_
...
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.
