juno: Add romlib support
...
This patch adds support to build a combined BL1
and ROMLIB binary file with the right page
alignment in Juno. When USE_ROMLIB=1 is set for
Juno, it generates the combined file
bl1_romlib.bin which needs to be used instead of
bl1.bin

plat/arm: Move norflash driver to drivers/ folder
...
This way it can be reused by other platforms if needed.
Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.
Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM
...
This option makes it hard to optimize the memory definitions of all Arm
platforms because any change in the common defines must work in all of
them. The best thing to do is to remove it and move the definition to
each platform's header.
FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.

juno: Revert FWU update detect mechanism
...
The patch 7b56928 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.

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.

ARM platforms: Fixup AArch32 builds
...
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.

These errata are only applicable to AArch64 state. See the errata notice
for more details:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.epm048406/index.html
Introduce the build options ERRATA_A53_835769 and ERRATA_A53_843419.
Enable both of them for Juno.
Apply the 835769 workaround as following:
* Compile with -mfix-cortex-a53-835769
* Link with --fix-cortex-a53-835769
Apply the 843419 workaround as following:
* Link with --fix-cortex-a53-843419
The erratum 843419 workaround can lead the linker to create new sections
suffixed with "*.stub*" and 4KB aligned. The erratum 835769 can lead the
linker to create new "*.stub" sections with no particular alignment.
Also add support for LDFLAGS_aarch32 and LDFLAGS_aarch64 in Makefile for
architecture-specific linker options.

CSS: Allow system suspend only via PSCI SYSTEM_SUSPEND API
...
The CSS power management layer previously allowed to suspend system
power domain level via both PSCI CPU_SUSPEND and PSCI SYSTEM_SUSPEND
APIs. System suspend via PSCI CPU_SUSPEND was always problematic to
support because of issues with targeting wakeup interrupts to
suspended cores before the per-cpu GIC initialization is done. This
is not the case for PSCI SYSTEM_SUSPEND API because all the other
cores are expected to be offlined prior to issuing system suspend and
PSCI CPU_ON explicit calls will be made to power them on. Hence the Juno
platform used to downgrade the PSCI CPU_SUSPEND request for system
power domain level to cluster level by overriding the default
`plat_psci_pm_ops` exported by CSS layer.
Given the direction the new CSS platforms are evolving, it is best to
limit the system suspend only via PSCI SYSTEM_SUSPEND API for all
CSS platforms. This patch makes changes to allow system suspend
only via PSCI SYSTEM_SUSPEND API. The override of `plat_psci_ops`
for Juno is removed.

Changes to support execution in AArch32 state for JUNO
...
Following steps are required to boot JUNO in AArch32 state:
1> BL1, in AArch64 state, loads BL2.
2> BL2, in AArch64 state, initializes DDR.
Loads SP_MIN & BL33 (AArch32 executable)images.
Calls RUN_IMAGE SMC to go back to BL1.
3> BL1 writes AArch32 executable opcodes, to load and branch
at the entrypoint address of SP_MIN, at HI-VECTOR address and
then request for warm reset in AArch32 state using RMR_EL3.
This patch makes following changes to facilitate above steps:
* Added assembly function to carry out step 3 above.
* Added region in TZC that enables Secure access to the
HI-VECTOR(0xFFFF0000) address space.
* AArch32 image descriptor is used, in BL2, to load
SP_MIN and BL33 AArch32 executable images.
A new flag `JUNO_AARCH32_EL3_RUNTIME` is introduced that
controls above changes. By default this flag is disabled.
NOTE: BL1 and BL2 are not supported in AArch32 state for JUNO.

Add workaround for ARM Cortex-A53 erratum 855873
...
ARM erratum 855873 applies to all Cortex-A53 CPUs.
The recommended workaround is to promote "data cache clean"
instructions to "data cache clean and invalidate" instructions.
For core revisions of r0p3 and later this can be done by setting a bit
in the CPUACTLR_EL1 register, so that hardware takes care of the promotion.
As CPUACTLR_EL1 is both IMPLEMENTATION DEFINED and can be trapped to EL3,
we set the bit in firmware.
Also we dump this register upon crashing to provide more debug
information.
Enable the workaround for the Juno boards.

Apply workaround for errata 813419 of Cortex-A57
...
TLBI instructions for EL3 won't have the desired effect under specific
circumstances in Cortex-A57 r0p0. The workaround is to execute DSB and
TLBI twice each time.
Even though this errata is only needed in r0p0, the current errata
framework is not prepared to apply run-time workarounds. The current one
is always applied if compiled in, regardless of the CPU or its revision.
This errata has been enabled for Juno.
The `DSB` instruction used when initializing the translation tables has
been changed to `DSB ISH` as an optimization and to be consistent with
the barriers used for the workaround.

ARM platforms: Define common image sizes
...
Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to
`ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines
related to the translation tables but to the image size as well.
The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and
`PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h.
This way, ARM platforms no longer have to set their own values if
`ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values
otherwise. The common sizes have been set to the highest values used
for any of the current build configurations.
This is needed because in some build configurations some images are
running out of space. This way there is a common set of values known
to work for all of them and it can be optimized for each particular
platform if needed.
The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been
increased. This is needed because when memory optimisations are
disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and
`MAX_XLAT_TABLES` are higher. If in this situation the code is
compiled in debug mode and with "-O0", the code won't fit.
