Revision C of the Base FVP has the same memory map as earlier revisions,
but has the following differences:
- Implements CCI550 instead of CCI400,
- Has a single instantiation of SMMUv3,
- CPU MPIDs are shifted left by one level, and has MT bit set in them.
The correct interconnect to program is chosen at run time based on the
FVP revision. Therefore, this patch implements FVP functions for
interconnect programming, rather than depending on ARM generic ones. The
macros used have been renamed to reflect this change.
Additionally, this patch initializes SMMUv3 as part of FVP early
platform setup.
New ARM config flags are introduced for feature queries at run time.

ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:
- The MT bit set;
- Affinity levels pertaining to cluster and CPUs occupy one level
higher than in a single-threaded implementation, and the lowest
affinity level pertains to hardware threads. MPIDR affinity level
fields essentially appear shifted to left than otherwise.
The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.
To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.
An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

plat_get_my_stack is called from C, so it can't expect argument
registers to be preserved. Stash registers temporarily onto the stack
instead.
plat_set_my_stack is called during early init, when there exists no

In a previous patch, the xlat_ctx_t type has been made public.
This patch now makes the *_ctx() APIs public.
Each API now has a *_ctx() variant. Most of them were already implemented
and this patch just makes them public. However, some of them were missing
so this patch introduces them.
Now that all these APIs are public, there's no good reason for splitting
them accross 2 files (xlat_tables_internal.c and xlat_tables_common.c).
Therefore, this patch moves all code into xlat_tables_internal.c and
removes xlat_tables_common.c. It removes it from the library's makefile
as well.
This last change introduces a compatibility break for platform ports
that specifically include the xlat_tables_common.c file instead of
including the library's Makefile. The UniPhier platform makefile has
been updated to now omit this file from the list of source files.
The prototype of mmap_add_region_ctx() has been slightly changed. The
mmap_region_t passed in argument needs to be constant because it gets
called from map_add(), which receives a constant region. The former
implementation of mmap_add() used to cast the const qualifier away,
which is not a good practice.
Also remove init_xlation_table(), which was a sub-function of
init_xlat_tables(). Now there's just init_xlat_tables() (and
init_xlat_tables_ctx()). Both names were too similar, which was
confusing. Besides, now that all the code is in a single file,
it's no longer needed to have 2 functions for that.

After disconnect Jumper pin 1-2 in J15 header, the signal VBUS_DET is to
be pulled down to low level. This will assert the interrupt signal in
PMIC and trigger IRQ in GIC; the asserted signal from VBUS_DET is level
triggered and kernel reports the warning for unhooked interrupt handling;
and VBUS_DET stays with low level, this triggers IRQ storm in kernel.
This patch is to disable interrupt for VBUS_DET in PMIC, this can
dismiss the verbose log and IRQ storm after kernel booting.

On ARM CSS platforms, the SCP_BL2/2U image is loaded below
BL1 read-write data. This same memory is used to load BL31
later on. But sufficient checks were not done to ensure that the
SCP_BL2 would not overwrite BL1 rw data. This patch adds the
required CASSERT checks to prevent overwrite into BL1 or BL2
memory by load of SCP_BL2/2U. Also the size of BL31 is increased
and SCP_BL2/2U size is decreased to accomodate it within the

The SCP_BL2 is transferred to SCP during BL2 image load and authenticate
sequence. The Boot-Over-MHU (BOM) protocol is used as transport for this. After
the SCP boots using the transferred image, the AP CPU waits till the `READY`
message is received from SCP. This patch separates the API for transport of
image from the wait for `READY` message and also moves the related files to
the `css/drivers` folder. The previous API `scp_bootloader_transfer` is
renamed to `css_scp_boot_image_xfer` to reflect the css naming convention.
This reorganisation also allows easier switch to a different transport
(eg: Shared Data Structure based transfer) in future

This patch fixes the two things as follows:
1) rk3399_flash_l2_b" seems to be a typo. That's "flush", not "flash".
2) fixes the warnings log.
We always hit the warnings thing during the suspend, as below log:
..
[ 51.022334] CPU5: shutdown
[ 51.025069] psci: CPU5 killed.
INFO: sdram_params->ddr_freq = 928000000
WARNING: rk3399_flash_l2_b:reg 28830380,wait
When the L2 completes the clean and invalidate sequence, it asserts the
L2FLUSHDONE signal. The SoC can now deassert L2FLUSHREQ signal and then
the L2 deasserts L2FLUSHDONE.
Then, a loop without a delay isn't really great to measure time. We should
probably add a udelay(10) or so in there and then maybe replace the WARN()
after the loop. In the actual tests, the L2 cache will take ~4ms by
default for big cluster.
In the real world that give 10ms for the enough margin, like the
ddr/cpu/cci frequency and other factors that will affect it.

This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:
* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.
* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.
* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

Before BL2 loads the SCP ram firmware, `SCP_BOOT_CFG_ADDR` specifies
the primary core. After the SCP ram firmware has started executing,
`SCP_BOOT_CFG_ADDR` is modified. This is not normally an issue but
the Juno AArch32 boot flow is a special case. BL1 does a warm reset
into AArch32 and the core jumps to the `sp_min` entrypoint. This is
effectively a `RESET_TO_SP_MIN` configuration. `sp_min` has to be
able to determine the primary core and hence we need to restore
`SCP_BOOT_CFG_ADDR` to the cold boot value before `sp_min` runs.
This magically worked when booting on A53 because the core index was
zero and it just so happened to match with the new value in
`SCP_BOOT_CFG_ADDR`.

Currently, ROTPK_NOT_DEPLOYED flag is set in plat_get_rotpk_info().
It is up to users how to retrieve ROTPK if the ROT verification is
desired. This is not nice.
This commit improves plat_get_rotpk_info() implementation and automates
the ROTPK deployment. UniPhier platform has no ROTPK storage, so it
should be embedded in BL1/BL2, like ARM_ROTPK_LOCATION=devel_rsa case.
This makes sense because UniPhier platform implements its internal ROM
i.e. BL1 is used as updatable pseudo ROM.
Things work like this:
- ROT_KEY (default: $(BUILD_PLAT)/rot_key.pem) is created if missing.
Users can override ROT_KEY from the command line if they want to
use a specific ROT key.
- ROTPK_HASH is generated based on ROT_KEY.
- ROTPK_HASH is included by uniphier_rotpk.S and compiled into BL1/BL2.
- ROT_KEY is input to cert_create tool.

The 'impl' variable is guarded by the symbol DEBUG, but used in an INFO
level print statement. INFO is defined based on LOG_LEVEL. Hence, builds
would fail when
- DEBUG=0 && LOG_LEVEL>=LOG_LEVEL_INFO with a variable used but not defined
- DEBUG=1 && LOG_LEVEL<LOG_LEVEL_INFO with a variable defined but not used
Fixing this by guarding impl with the same condition that guards INFO.

function for rockchip platform, so we need to check wakeup

This moves the DRAM restore code to PMUSRAM. This is so that the
voltage domain that contains the SRAM that it was stored in before may
be turned off during system suspend.

it is in does to break out of the for loop, so it doesn't make any
sense to keep it there.

This removes the mmio_... function calls to set the multicast bit for
the PHY registers when overriding the write leveling values. These are
not needed since multicast is set by default when calling the
function, and it's also better not to leave the side effect of
disabling multicast when exiting the function.

This removes the phy_dll_bypass_set function as it is unneeded. The
values that function sets are saved during suspend, so the proper

This removes the space allocation for the unused PHY register space.
For instance in PHY registers 0-127, only 0-90 are used, so don't save
the 91-127 registers. This saves about 1.6KB of space.

The differential signal of DQS need keep low level
before gate training. It need enable RPULL and disable
PHY side ODT to ensure it when do gate training.
But it can not access the PHY registers to do it when
perform DFS.So the workaroud as below: It is ensure that
the PHY's read gate is landing somewhere in the incoming
DQS's pulses before it starts searching for pre-amble window.
It need get the rddqs_delay_ps to calculate the start point
of gate training for DFS.
