* changes:
  N1SDP: Initialise CNTFRQ in Non Secure CNTBaseN
  N1SDP: Fix DRAM2 start address
  Add option for defining platform DRAM2 base
  Disable speculative loads only if SSBS is supported

N1SDP exhibits the behavior similar to Juno wherein CNTBaseN.CNTFRQ
can be written but does not reflect the value of the CNTFRQ register
in CNTCTLBase frame. This doesn't follow ARM ARM in that the value
updated in CNTCTLBase.CNTFRQ is not reflected in CNTBaseN.CNTFRQ.

Hence enable the workaround (applied to Juno) for N1SDP that updates
the CNTFRQ register in the Non Secure CNTBaseN frame.

The default DRAM2 start address for Arm platforms
is 0x880000000. However, for N1SDP platform this is
0x8080000000.

Fix the DRAM2 start address by initialising
PLAT_ARM_DRAM2_BASE.

Without this fix there is a mismatch of the System
memory region view as seen by the BL31 runtime
firmware (PSCI) versus the view of the OS (which
is based on the description provided by UEFI. In
this case UEFI is correctly describing the DRAM2
start address).

This implicates in secondary cores failing to start
on some Operating Systems if the OS decides to place
the secondary start address in the mismatched region.

The default DRAM2 base address for Arm platforms
is 0x880000000. However, on some platforms the
firmware may want to move the start address to
a different value.

To support this introduce PLAT_ARM_DRAM2_BASE that
defaults to 0x880000000; but can be overridden by
a platform (e.g. in platform_def.h).

We've seen issues with some THG based UFS chips, where
after reset the LUNs don't always enumerate properly.

After some debugging, we found that extending the mdelay
here seems to resolve the issue by giving the chips enough
time to complete reset.

This patch removes .arch "arm8.1-a" and "armv8-a"
directives which overwrite ASFLAGS_aarch64 option based
on ARM_ARCH_MINOR passed to Makefile and cause
translation errors like
"selected processor does not support `bti jc'"
for armv8.5-a targets when BTI support is enabled.

For security DMA should be blocked at the SMMU by default
unless explicitly enabled for a device. SMMU is disabled
after reset with all streams bypassing the SMMU, and
abortion of all incoming transactions implements a default
deny policy on reset.
This patch also moves "bl1_platform_setup()" function from
arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and
fvp_ve_bl1_setup.c files.

The IMX_SIP_BUILDINFO call was implemented for imx8qm and imx8qx but
it's also applicable to imx8m.

This fixes U-Boot not printing commit hash on 8m with upstream TF-A.

This patch fixes this issue:
https://github.com/ARM-software/tf-issues/issues/660



The introduced changes are the following:

1) Some cores implement cache coherency maintenance operation on the
hardware level. For those cores, such as - but not only - the DynamIQ
cores, it is mandatory that TF-A is compiled with the
HW_ASSISTED_COHERENCY flag. If not, the core behaviour at runtime is
unpredictable. To prevent this, compile time checks have been added and
compilation errors are generated, if needed.

2) To enable this change for FVP, a logical separation has been done for
the core libraries. A system cannot contain cores of both groups, i.e.
cores that manage coherency on hardware and cores that don't do it. As
such, depending on the HW_ASSISTED_COHERENCY flag, FVP includes the
libraries only of the relevant cores.

3) The neoverse_e1.S file has been added to the FVP sources.

This patch is a preparation for the subsequent changes in
SMMUv3 driver. It introduces a new "smmuv3_poll" function
and replaces inline functions for accessing SMMU registers
with mmio read/write operations. Also the infinite loop
for the poll has been replaced with a counter based timeout.

* changes:
  rockchip: Disable binary generation for all SoCs.
  build_macros: Add mechanism to prevent bin generation.

All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
have non-continuous memory areas in the linker script with a huge
gap between them. This results in extremely padded binary images
with a size of about 4 GiB.

E.g. on the RK3399 we have the following memory areas (and base addresses):
RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).

Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
use the ELF image instead, which has a size of a few hundred kBs.

In order to prevent the generation of a huge and useless file,
this patch disables the binary generation for all affected Rockchip
SoCs.
