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.

Improve MULTI_CONSOLE_API deprecation warnings

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.

This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.

For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.

This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.

Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

Select SCMI/SDS drivers by default on Juno

The SCP binaries provided in the 17.10 Linaro release (and onwards)
have migrated to the SCMI/SDS protocols. Therefore, the ARM TF should
now use the corresponding drivers by default.

This patch changes the default value of the CSS_USE_SCMI_SDS_DRIVER
build option to 1 for Juno.

6 years agoInvalidate TLB entries during warm boot
Antonio Nino Diaz [Mon, 19 Feb 2018 16:27:06 +0000 (16:27 +0000)]
Invalidate TLB entries during warm boot

During the warm boot sequence:

1. The MMU is enabled with the data cache disabled. The MMU table walker
   is set up to access the translation tables as in cacheable memory,
   but its accesses are non-cacheable because SCTLR_EL3.C controls them
   as well.
2. The interconnect is set up and the CPU enters coherency with the
   rest of the system.
3. The data cache is enabled.

If the support for dynamic translation tables is enabled and another CPU
makes changes to a region, the changes may only be present in the data
cache, not in RAM. The CPU that is booting isn't in coherency with the
rest of the system, so the table walker of that CPU isn't either. This
means that it may read old entries from RAM and it may have invalid TLB
entries corresponding to the dynamic mappings.

This is not a problem for the boot code because the mapping is 1:1 and
the regions are static. However, the code that runs after the boot
sequence may need to access the dynamically mapped regions.

This patch invalidates all TLBs during warm boot when the dynamic
translation tables support is enabled to prevent this problem.

6 years agoEHF: Introduce preempted return code parameter to ehf_allow_ns_preemption()

EHF: Introduce preempted return code parameter to ehf_allow_ns_preemption()

When a Yielding SMC is preempted, it's possible that Non-secure world is
resumed afterwards. In this case, Non-secure execution would find itself
in a state where the SMC has returned. However, the dispatcher might not
get an opportunity to populate the corrected return code for having
been preempted, and therefore the caller of the Yielding SMC cannot
reliably determine whether the SMC had successfully completed or had
been preempted.

To solve this, this patch introduces a new parameter to the
ehf_allow_ns_preemption() API. An SPD, through this parameter, would
provide the expected error code when a Yielding SMC is preempted. EHF
can then populate the specified value in x0 of the Non-secure context so
that the caller of the Yielding SMC correctly identifies the SMC return
as a preemption.

Documentation updates to follow.

SDEI: Pop dispatch context only after error checking

Currently, when the client attempts to do SDEI_EVENT_COMPLETE or
SDEI_EVENT_COMPLETE_AND_RESUME, the dispatcher pops off the outstanding
dispatch context for sanity check. There are however other checks
following this, which could potentially return failure. If that happens,
by popping the context, the dispatcher has inadvertently discarded a
valid context.

This patch fixes this bug by inspecting (not actually popping) the
outstanding context. The context is popped only after all error checks
are completed.
