Following the messages on the mailing list regarding the possible issue around
reading DTB's information, we decided to flag the fconf feature as experimental.
A uniform approach should be used to handle properties miss and DTB validation.

 - Include the platform documentation in the table of contents.

 - Add a title for the document. Without this, the platform
   documentation was listed under a 'Description' title on page
   https://trustedfirmware-a.readthedocs.io/en/latest/plat/index.html



 - Change TF-A git repository URL to point to tf.org (rather than the
   deprecated read-only mirror on Github).

 - Fix the restructuredText syntax for the FIP command line. It was
   not displayed at all on the rendered version.

A single chip platform requires five mmap entries and a corresponding
number of translation tables. For every additional chip in the system,
three additional mmap entries are required to map the shared SRAM and
the IO regions. A corresponding number of additional translation
tables are required as well.

The arm_fpga platform code contains an dubious line to initialise some
timer. On closer inspection this turn out to be bogus, as this was only
needed on some special (older) FPGA board, and is actually not needed on
the current model. Also the base address was wrong anyways.

Remove the code entirely.

To support compatibility with previous GICv3 driver version
this patch:
- restores original API for gicr_read_ipriority() and
gicr_wrtite_ipriority() functions;
- adds accessor functions for GICR_XXX0,1 registers, e.g.
GICR_IGROUPR0, GICR_ICFGR0, GICR_ICFGR1, etc.

RD-Daniel uses GIC-Clayton as its interrupt controller which is an
implementation of GICv4.1 architecture. Hence for RD-Daniel, enable
GICv4 extension support.

GIC-Clayton supports multichip operation mode which allows it to connect
upto 16 other GIC-Clayton instances. GIC-Clayton's multichip programming
and operation remains same as GIC-600 with a minor change in the
SPI_BLOCKS and SPI_BLOCK_MIN shifts to accommodate additional SPI
ranges. So identify if the GIC v4 extension is enabled by the platform
makefile and appropriately select the SPI_BLOCKS and SPI_BLOCK_MIN
shifts.

This patch adds support for GICv4 extension.
New `GIC_ENABLE_V4_EXTN` option passed to gicv3.mk makefile
was added, and enables GICv4 related changes when set to 1.
This option defaults to 0.

This patch adds code to parse memory range information passed by
coreboot, and a simple helper to test whether a specific address belongs
to a range. This may be useful for coreboot-using platforms that need to
know information about the system's memory layout (e.g. to check whether
an address passed in via SMC targets valid DRAM).

Increased the maximum size of BL2 image in order to
accommodate the BL2 image when TF-A build with no compiler
optimization for ARM platform.

Note: As of now, "no compiler optimization" build works
only when TRUSTED_BOOT_BOARD option is set to 0.

This change is verified using below CI configuration:
1. juno-no-optimize-default:juno-linux.uboot
2. fvp-no-optimize-default,fvp-default:fvp-tftf-fip.tftf-aemv8a-debug

bakery_lock_normal.c uses the raw register accessor, read_sctlr(_el3)
to check whether the dcache is enabled.

Using is_dcache_enabled() is cleaner, and a good abstraction for
the library code like this.

A problem is is_dcache_enabled() is declared in the local header,
lib/xlat_tables_v2/xlat_tables_private.h

I searched for a good place to declare this helper. Moving it to
arch_helpers.h, closed to cache operation helpers, looks good enough
to me.

I also changed the type of 'is_cached' to bool for consistency,
and to avoid MISRA warnings.

This patch provides support for GICv3.1 extended PPI and SPI
range. The option is enabled by setting to 1 and passing
`GIC_EXT_INTID` build flag to gicv3.mk makefile.
This option defaults to 0 with no extended range support.
