Varun Wadekar d48c0c45de Tegra: memctrl_v2: secure the on-chip TZSRAM memory
This patch programs the Memory controller's control registers
to disable non-secure accesses to the TZRAM. In case these
registers are already programmed by the BL2/BL30, then the
driver just bails out.

Varun Wadekar b5ef956927 Tegra186: relocate bl31.bin to the SYSRAM
Tegra186 has an on-die, 320KB, "System RAM" memory. Out of the total
size, 256KB are allocated for the CPU TrustZone binaries - EL3 monitor
and Trusted OS.

This patch changes the base address for bl31.bin to the SysRAM base
address. The carveout is too small for the Trusted OS, so we relocate
only the monitor binary.

Varun Wadekar b47d97b395 Tegra186: power on/off secondary CPUs
This patch add code to power on/off the secondary CPUs on the Tegra186
chip. The MCE block is the actual hardware that takes care of the
power on/off sequence. We pass the constructed CPU #, depending on the

This patch also programs the reset vector addresses to allow the
CPUs to power on through the monitor and then jump to the linux
world.

Varun Wadekar 7808b06b99 Tegra186: mce: driver for the CPU complex power manager block
The CPU Complex (CCPLEX) Power Manager (Denver MCE, or DMCE) is an
offload engine for BPMP to do voltage related sequencing and for
hardware requests to be handled in a better latency than BPMP-firmware.

There are two interfaces to the MCEs - Abstract Request Interface (ARI)
and the traditional NVGINDEX/NVGDATA interface.

MCE supports various commands which can be used by CPUs - ARM as well
as Denver, for power management and reset functionality. Since the
linux kernel is the master for all these scenarios, each MCE command
can be issued by a corresponding SMC. These SMCs have been moved to
SiP SMC space as they are specific to the Tegra186 SoC.

Tegra186 is the newest SoC in the Tegra family which consists

cores on this SoC would be available to the system at the same
time and individual clusters can be powered down to conserve
power.

Andre Przywara b75dc0e41c 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.

Antonio Nino Diaz bf75a3710c ARM platforms: Enable xlat tables lib v2
Modify ARM common makefile to use version 2 of the translation tables

The following table contains information about the size increase in

different configurations of FVP in AArch64 mode with compiler GCC 4.9.3
20150413. The sizes have been calculated with the output of `nm` by
adding the size of all regions and comparing the total size before and

Antonio Nino Diaz ccbec91c0c 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.

Varun Wadekar 78e2bd10ae Tegra: implement FIQ interrupt handler
This patch adds a handler for FIQ interrupts triggered when
the CPU is in the NS world. The handler stores the NS world's
context along with ELR_EL3/SPSR_EL3.

The NS world driver issues an SMC initially to register it's
handler. The monitor firmware stores this handler address and
jumps to it when the FIQ interrupt fires. Upon entry into the
NS world the driver then issues another SMC to get the CPU
context when the FIQ fired. This allows the NS world driver to
determine the CPU state and call stack when the interrupt
fired. Generally, systems register watchdog interrupts as FIQs
which are then used to get the CPU state during hangs/crashes.

Varun Wadekar d336030169 Tegra: GIC: enable FIQ interrupt handling
Tegra chips support multiple FIQ interrupt sources. These interrupts
are enabled in the GICD/GICC interfaces by the tegra_gic driver. A
new FIQ handler would be added in a subsequent change which can be
registered by the platform code.

This patch adds the GIC programming as part of the tegra_gic_setup()
which now takes an array of all the FIQ interrupts to be enabled for
the platform. The Tegra132 and Tegra210 platforms right now do not
register for any FIQ interrupts themselves, but will definitely use
this support in the future.

Varun Wadekar 2693f1dbc7 Tegra: implement common handler `plat_get_target_pwr_state()`
This patch adds a platform handler to calculate the proper target power
level at the specified affinity level.

Tegra platforms assign a local state value in order of decreasing depth
of the power state i.e. for two power states X & Y, if X < Y then X
represents a shallower power state than Y. As a result, the coordinated
target local power state for a power domain will be the maximum of the
requested local power state values.

steps (compiling, assembling, linking) actually call GCC, remove the
misleading aliases $(AS) and $(LD) to avoid confusion that those tools
might be called directly. Split flags into a common group that has
meaning for all three steps and separate variables specific to each
step. Remove -nostartfiles which is a strict subset of -nostdlib.

Also add explicit parameters for -mfloat-abi=soft, -fomit-frame-pointer
and -fno-common. If omitted these settings depend on the toolchain's
built-in default and cause various problems if they resolve to
unexpected values.

Varun Wadekar e10842167b Tegra: init normal/crash console for platforms
The BL2 fills in the UART controller ID to be used as the normal as
well as the crash console on Tegra platforms. The controller ID to
UART controller base address mapping is handled by each Tegra SoC
the base addresses might change across Tegra chips.

This patch adds the handler to parse the platform params to get the
UART ID for the per-soc handlers.

Varun Wadekar e0d4158c71 Tegra: add tzdram_base to plat_params_from_bl2 struct
This patch adds another member, tzdram_base, to the plat_params_from_bl2 struct
in order to store the TZDRAM carveout base address used to load the Trusted OS.
The monitor programs the memory controller with the TZDRAM base and size in order
to deny any accesses from the NS world.
