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 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.

Merge "xlat lib v2: Add support to pass shareability attribute for normal memory region" into integration

* changes:
  doc: brcm: Add documentation file for brcm stingray platform
  drivers: Add SPI Nor flash support
  drivers: Add iproc spi driver
  drivers: Add emmc driver for Broadcom platforms
  Add BL31 support for Broadcom stingray platform
  Add BL2 support for Broadcom stingray platform
  Add bl31 support common across Broadcom platforms
  Add bl2 setup code common across Broadcom platforms
  drivers: Add support to retrieve plat_toc_flags

Present framework restricts platform to pass desired shareability attribute
for normal memory region mapped in MMU. it defaults to inner shareability.

There are platforms where memories (like SRAM) are not placed at snoopable
region in advaned interconnect like CCN/CMN hence snoopable transaction is
not possible to these memory. Though These memories could be mapped in MMU
as MT_NON_CACHEABLE, data caches benefits won't be available.

If these memories are mapped as cacheable with non-shareable attribute,
when only one core is running like at boot time, MMU data cached could be
used for faster execution. Hence adding support to pass the shareability
attribute for memory regions.

Using get_current_el_maybe_constant() produces more optimized code
because in most cases, we know the exception level at build-time.
For example, BL31 runs at EL3, so unneeded code will be trimmed.
