All the arm platforms were including the files related to
mem-protect. This configuration generates some problems
with new platforms that don't support such functionality,
and for that reason this patch moves these files to the
platform specific makefiles.

cpus: denver: report CVE_2017_5715 mitigation to higher layers

rockchip: Add plat_is_my_cpu_primary function

DSU erratum 936184 workaround

This patch uses the 'declare_cpu_ops_wa' macro, to set the check function,
to report that Denver cores are mitigated.

Denver cores are vulnerable to this anomaly and require the mitigation to
be enabled always.

DTC: Add recommended device tree compiler version

If the system is in near idle conditions, this erratum could cause a
deadlock or data corruption. This patch applies the workaround that
prevents this.

This DSU erratum affects only the DSUs that contain the ACP interface
and it was fixed in r2p0. The workaround is applied only to the DSUs
that are actually affected.

rpi3: Remove dependencies on Arm platform code

Fix typo in documentation page title

Console: Use callee-saved registers

The Raspberry Pi 3 port doesn't actually depend on any Arm platform
code, so the dependencies can be removed.

Replace stdio.h functions by TF functions

readme: Add information about the TF-A IRC channel

cci: Use dsb to wait before reading status register

The CCI500 TRM explicitily requires completion of the write
operation before the read operation, and it is not guaranteed
by dmb but it is dsb.

The translation library is useful elsewhere. Even though this repository
doesn't exercise the EL2 support of the library, it is better to have it
here as well to make it easier to maintain.

enable_mmu_secure() and enable_mmu_direct() have been deprecated. The
functions are still present, but they are behind ERROR_DEPRECATED and
they call the new functions enable_mmu_svc_mon() and
enable_mmu_direct_svc_mon().

DMA is always used in mmc driver. So the buffer address should
always follow the DMA limitation.

There're same requirement in mmc_read_blocks()/mmc_write_blocks()
on parameter buf. Since parameter buf comes from io_block driver,
it's already handled in io_block driver.

At here, just make the minimum address alignment on 16 chars.

mmc_read_blocks()/mmc_write_blocks() derived from io_block_ops_t
type. It means that lba param should be integer type, not
unsigned integer type.

mmc: add required delays when retrying commands

Functions provided by stdio.h such as printf and sprintf are available
in the codebase, but they add a lot of code to the final image if they
are used:

- AArch64: ~4KB
- AArch32: ~2KB in T32, ~3KB in A32

tf_printf and tf_snprintf are a lot more simple, but it is preferable
to use them when possible because they are also used in common code.
