Update the memory firewall configuration to reserve 4 MB of secure RAM
for use by the kernel and OP-TEE as the Secure Data Path pool.
Note that this address range (0x3E800000 - 0x3EC00000) falls in the
range already set aside by UEFI (which reserves the upper 32 MB of the
1GB DRAM for OP-TEE [1]) and was previously unused.

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.

For rk3399, the L2ACTLR[14] is 0 by default, as ACE CCI-500 doesn't
support WriteEvict. and you will hit the condition L2ACTLR[3] with 0,
as the Evict transactions should propagate to CCI-500 since it has
snoop filters.

Maybe this erratum applies to all Cortex-A53 cores so far, especially
if RK3399's A53 is a r0p4. we should enable it to avoid data corruption,

On Juno AArch32, the L2 cache may contain garbage after the warm reset
from AArch64 to AArch32.  This is all fine until the MMU is configured
and the data caches enabled.  To avoid fetching stale data from the L2
unified cache, invalidate it before the warm reset to AArch32 state.

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`.

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.

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.

In CPU off callback function, the old code uses the function
hisi_test_pwrdn_allcores() to check if all CPUs in cluster have been
powered off and if it's valid then power off the whole cluster. But the
function hisi_test_pwrdn_allcores() only maintains the different power
states only for CPU suspend/resume flow, so it cannot return correct
states for CPU on/off flow.

This patch is to change use hisi_test_cpu_down() to check if all CPUs
have been powered off, so that can power off the whole cluster properly
when all CPUs in cluster have been hotplugged off.

The ARM_PLAT_MT bit enables the support for MT bit in

represents the thread and CPU / Cluster levels are
at affinity level 1 and 2 respectively.
This was not catered for in the scpi 'css_scp_get_power_state, API.
Since the SCPI driver can only cater for single threaded CPUs,
this patch fixes the problem by catering for this shift by
effectively ignoring the Thread (level 0) affinity level.
