uniphier: increase BL33 max size and GZIP temporary buffer size
...
The current BL33 size is large enough for U-Boot, but we need to
increase the limit to use other boot loaders such as edk2.
Increase the buffer size used for GZIP decompression too.
BL33 max size (UNIPHIER_BL33_MAX_SIZE): 1MB -> 8MB
GZIP buffer (UNIPHIER_IMAGE_BUF_SIZE): 1MB -> 8MB
Increasing the block buffer size (UNIPHIER_BLOCK_BUF_SIZE) is not
required, but I increased it too to make it work more efficiently.

uniphier: use enable_mmu() in common function
...
Currently, enable_mmu_el1() or enable_mmu_el3() is kept outside the
common function because the appropriate one must be chosen.
Use enable_mmu() and move it to the common function.

uniphier: make all BL images completely position-independent
...
This platform supports multiple SoCs. The next SoC will still keep
quite similar architecture, but the memory base will be changed.
The ENABLE_PIE improves the maintainability and usability. You can reuse
a single set of BL images for other SoC/board without re-compiling TF-A
at all. This will also keep the code cleaner because it avoids #ifdef
around various base addresses.
By defining ENABLE_PIE, BL2_AT_EL3, BL31, and BL32 (TSP) are really
position-independent now. You can load them anywhere irrespective of
their link address.

uniphier: make uniphier_mmap_setup() work with PIE
...
BL2_BASE, BL31_BASE, and BL32_BASE are defined in platform_def.h,
that is, determined at link-time.
On the other hand, BL2_END, BL31_END, and BL32_END are derived from
the symbols produced by the linker scripts. So, they are fixed-up
at run-time if ENABLE_PIE is enabled.
To make it work in a position-indepenent manner, use BL_CODE_BASE and
BL_END, both of which are relocatable.

uniphier: pass SCP base address as a function parameter

Currently, uniphier_bl2_mmap hard-codes the memory region needed for

Towards the goal of making this really position-independent, call
mmap_add_dynamic_region() before that region gets accessed.

Remove duplicated definitions of linker symbols
...
Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.
As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

Sanitise includes across codebase
...
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

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
command line.
- Images are GZIP-compressed, then packed into FIP. If Trusted Board
Boot is enabled, certificates are generated based on the compressed
images.
- GZIP decompressor is linked into BL2 to decompress images at
run-time.

UniPhier platform implements non-TF boot ROM. Prior to the BL2-AT-EL3
support, BL1 (worked as a pseudo ROM) was needed just for ensuring BL2
is entered at EL1-S. Now, this platform is able to avoid this waste.
Enable the BL2_AT_EL3 option, and remove BL1.
