Added a build flag to select the generic delay timer on FVP instead
of the SP804 timer. By default, the generic one will be selected. The
user guide has been updated.

Add delay timer implementation based on the system generic counter.
This either uses the platform's implementation of
`plat_get_syscnt_freq()` or explicit clock multiplier/divider values
provided by the platform.
The current implementation of udelay has been modified to avoid
unnecessary calculations while waiting on the loop and to make it
easier to check for overflows.

Added plat_get_syscnt_freq2, which is a 32 bit variant of the 64 bit
plat_get_syscnt_freq. The old one has been flagged as deprecated.
Common code has been updated to use this new version. Porting guide
has been updated.

Allow to handle cases where some images are pre-loaded (by debugger for

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.

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.

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

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.

The translation table library code has moved from lib/aarch64/ to
lib/xlat_tables/ since commit 3ca9928df but the Porting Guide still
points to the old location. This patch fixes this issue.

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.

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
`749ade4`, for platforms that use arm_common.c but do not
provide a memory mapped interface to the generic counter.

Drop the current configuration options for selecting the location of
the ATF and TSP (ZYNQMP_ATF_LOCATION, ZYNQMP_TSP_RAM_LOCATION).
The new configuration provides one default setup (ATF in OCM,
BL32 in DRAM). Additionally, the new configuration options
- ZYNQMP_ATF_MEM_BASE
- ZYNQMP_ATF_MEM_SIZE
- ZYNQMP_BL32_MEM_BASE
- ZYNQMP_BL32_MEM_SIZE
can be used to freely configure the memory locations used for ATF and
secure payload.
Also, allow setting the BL33 entry point via PRELOADED_BL33_BASE.

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:

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.
