hikey960: avoid hardcode on uart port

tegra: Fix mmap_region_t struct mismatch ...

Commit fdb1964 ("xlat: Introduce
MAP_REGION2() macro") added a granularity field to mmap_region_t.

Tegra platforms were using the v2 xlat_tables implementation in
common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c
where arrays are being defined. This caused the next physical address to
be read as granularity, causing EINVAL error and triggering an assert.

Consistently use xlat_tables_v2.h header to avoid this.

Fixes ARM-software/tf-issues#548.

ARM platforms: Fix console address for flush ...

The console core flush API expects the base address in the first
register, but ARM helpers currently sets the second register with the
base address. This causes an assert failure.

This patch fixes that.

qemu: Fix interrupt type check ...

Function plat_ic_get_pending_interrupt_type() should return interrupt
type, not id. The function is used in aarch64 exception handling and
currently the irq/fiq forwarding fails if a secure interrupt happens while
running normal world.

The qemu-specific gic file does not contain any extra functionality so it
can be removed and common file can be used instead.

Merge pull request #1224 from masahir0y/gzip ...

Support GZIP-compressed images for faster loading and verification

qemu: support ARMv7/Cortex-A15 ...

Define Qemu AArch32 implementation for some platform functions
(core position, secondary boot cores, crash console). These are
derived from the AArch64 implementation.

BL31 on Qemu is needed only for ARMv8 and later. On ARMv7, BL32 is
the first executable image after BL2.

Support SP_MIN and OP-TEE as BL32: create a sp_min make script target
in Qemu, define mapping for IMAGE_BL32

Minor fix Qemu return value type for plat_get_ns_image_entrypoint().

Qemu model for the Cortex-A15 does not support the virtualization
extension although the core expects it. To overcome the issue, Qemu
ARMv7 configuration set ARCH_SUPPORTS_VIRTUALIZATION to 0.

Add missing AArch32 assembly macro arm_print_gic_regs from ARM platform
used by the Qemu platform.

Qemu Cortex-A15 model integrates a single cluster with up to 4 cores.

uniphier: allocate xlat region of on-chip SRAM only when needed ...

Currently, the xlat region of the on-chip SRAM is always allocated
for all BL images.

The access to the on-chip SRAM is necessary for loading images from
a USB memory device (i.e. when updating firmware), so unneeded for
the usual boot procedure.

To avoid this waste, allocate the xlat region dynamically only for
BL2, and only when it is necessary.

uniphier: get back original BL31/32 location used before BL2-AT-EL3 ...

Commit 247fc0435191 ("uniphier: switch to BL2-AT-EL3 and remove BL1
support") accidentally changed the location of BL31 and BL32.  The
new memory map overlaps with the audio DSP images, also gives impact
to OP-TEE.  They are both out of control of ARM Trusted Firmware, so
not easy to change.  This commit restores the image layout that was
originally used prior to the BL2-AT-EL3 migration.

Allow to handle GZIP-compressed images by giving FIP_GZIP=1 from the

- Images are GZIP-compressed, then packed into FIP.  If Trusted Board

  images.

- GZIP decompressor is linked into BL2 to decompress images at
  run-time.

In the next commit, I will have more usecases to get struct image_info

the code is small enough to be squashed into the caller side.

There are cases where we need to manipulate image information before

compressed images to their final destination.  Instead, we need to
load them to the temporary buffer for the decompressor.

plat/common: move arch-agnostic fallback functions to C file ...

When we add a new callback, we need to duplicate fallbacks among
plat/common/{aarch32,aarch64}/platform_helpers.S  This is tedious.

I created a new C file, then moved 3 functions:
  plat_error_handler
  bl2_plat_preload_setup
  plat_try_next_boot_source

They are called from C, so I do not see a good reason to implement
them in assembly.

Build: change the first parameter of TOOL_ADD_IMG to lowercase ...

In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.

Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.

make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist.  We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.

Build: merge build macros between FIP_ and FWU_FIP_ ...

The build system supports generating two FIP images, fip and fwu_fip.
Accordingly, we have similar build macros.

   FIP_ADD_PAYLOAD   <-->  FWU_FIP_ADD_PAYLOAD
   CERT_ADD_CMD_OPT  <-->  FWU_CERT_ADD_CMD_OPT
   FIP_ADD_IMG       <-->  FWU_FIP_ADD_IMG

The duplicated code increases the maintenance burden.  Also, the build
rule of BL2U looks clumsy - we want to call MAKE_BL to compile it from
source files, but we want to put it in fwu_fip.  We can not do it in a
single macro call since the current MAKE_BL does not support fwu_fip.

To refactor those in a clean way is to support one more argument to
specify the FIP prefix.  If it is empty, the images are targeted to
fip, whereas if the argument is "FWU_", targeted to fwu_fip.

The build macros prefixed with FWU_ go away.
