FVP: Remove VE memory map support and change default GIC driver

Refactor MediaTek platform common code for further mt6795 upstream.

This patch changes the default driver for FVP platform from the deprecated
GICv3 legacy to the GICv3 only driver. This means that the default build of
Trusted Firmware will not be able boot Linux kernel with GICv2 FDT blob. The
user guide is also updated to reflect this change of default GIC driver for
FVP.

Change-Id: Id6fc8c1ac16ad633dabb3cd189b690415a047764

This patch removes support for legacy Versatile Express memory map for the
GIC peripheral in the FVP platform. The user guide is also updated for the
same.

Emmc v3

In a lot of embedded platforms, eMMC device is the only one storage
device. So loading content from eMMC device is required in ATF.

Create the emmc stack that could co-work with IO block driver.
Support to read/write/erase eMMC blocks on both rpmb and normal
user area. Support to change the IO speed and bus width.

Add MAX_IO_BLOCK_DEVICES in porting guide. It's necessary to define
this macro to support io block device. With this macro, multiple
block devices could be opened at the same time. Each block device
stores its own state.

FIP is accessed as memory-mapped type. eMMC is block device type.
In order to support FIP based on eMMC, add the new io_block layer.

io_block always access eMMC device as block size. And it'll only
copy the required data into buffer in io_block driver. So preparing
an temporary buffer is required.

When use io_block device, MAX_IO_BLOCK_DEVICES should be declared
in platform_def.h. It's used to support multiple block devices.

Fix computation of L1 bitmask in the translation table lib

The translation table library code has moved from lib/aarch64/ to
lib/xlat_tables/ since commit 3ca9928d but the Porting Guide still
points to the old location. This patch fixes this issue.

Change-Id: I983a9a100d70eacf6bac71725ffbb4bb5f3732b0

This patch fixes the computation of the bitmask used to isolate
the level 1 field of a virtual address. The whole computation needs
to work on 64-bit values to produce the correct bitmask value.
XLAT_TABLE_ENTRIES_MASK being a C constant, it is a 32-bit value
so it needs to be extended to a 64-bit value before it takes part
in any other computation.

This patch fixes this bug by casting XLAT_TABLE_ENTRIES_MASK as
an unsigned long long.

Note that this bug doesn't manifest itself in practice because
address spaces larger than 39 bits are not yet supported in the
Trusted Firmware.

Conditionally compile `plat_get_syscnt_freq()` in ARM standard platforms

This patch puts the definition of `plat_get_syscnt_freq()`
under `#ifdef ARM_SYS_CNTCTL_BASE` in arm_common.c file.
This is the fix for compilation error introduced by commit-id
`749ade45`, for platforms that use arm_common.c but do not
provide a memory mapped interface to the generic counter.

Fixes ARM-software/tf-issues#395

Validate psci_cpu_on_start() arguments

rockchip: fixes for the required

Move `plat_get_syscnt_freq()` to arm_common.c

The "end power level" value passed as the 3rd argument to the
psci_cpu_on_start() function is not used so this patch removes it.

Change-Id: Icaa68b8c4ecd94507287970455fbff354faaa41e

This patch introduces some debug assertions in the function
psci_cpu_on_start() to check the arguments it receives are
valid.

Change-Id: If4d23c9f668fb46f2d18c5e2ed1929498cc6736b

This patch has the following change for rk3399.

* Set the uart to 115200 since the loader decide to set
  uart baud to 115200Hz. So the ATF also should set uart baud to 115200.

* We need ensure the bl31 base is greater than 4KB since there are have
  the shared mem for coreboot.(Note: the previous vesion was tested with uboot)

Otherwise, we will happen the exception crash since the ddr area won't
to work from the shared ram address in some cases.

For example, the exception crash:
CBFS: Found @ offset 19c80 size 24074
exception _sync_sp_el0
ELR = 0x0000000000008000

Cortex-A57 errata workarounds

Limit support for region overlaps in xlat_tables

This patch moves the definition for `plat_get_syscnt_freq()`
from arm_bl31_setup.c to arm_common.c. This could be useful
in case a delay timer needs to be installed based on the
generic timer in other BLs.
This patch also modifies the return type for this function
from `uint64_t` to `unsigned long long` within ARM and other
platform files.

Add support for unoptimised (-O0) build

The only case in which regions can now overlap is if they are
identity mapped or they have the same virtual to physical address
offset (identity mapping is just a particular case of the latter).
They must overlap completely (i.e. one of them must be completely
inside the other one) and not cover the same area.

This allow future enhancements to the xlat_tables library without
having to support unnecessarily complex edge cases.

Outer regions are now sorted by mmap_add_region() before inner
regions with the same base virtual address for consistency: all
regions contained inside another one must be placed after the outer
one in the list.

If an inner region has the same attributes as the outer ones it will
be merged when creating the tables with init_xlation_table(). This
cannot be done as regions are added because there may be cases where
adding a region makes previously mergeable regions no longer
mergeable.

If the attributes of an inner region are different than the outer
region, new pages will be generated regardless of how "restrictive"
they are. For example, RO memory is more restrictive than RW. The
old implementation would give priority to RO if there is an overlap,
the new one doesn't.

NOTE: THIS IS THEORETICALLY A COMPATABILITY BREAK FOR PLATFORMS THAT
USE THE XLAT_TABLES LIBRARY IN AN UNEXPECTED WAY. PLEASE RAISE A
TF-ISSUE IF YOUR PLATFORM IS AFFECTED.
