Masahiro Yamada 2765ffdc99 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.

Masahiro Yamada c64873ab94 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.

Masahiro Yamada 4dd4bde4b7 uniphier: fix typo and coding style
Fix the typo "warn" -> "warm".

Also fix the following checkpatch.pl warnings:

  CHECK: Prefer using the BIT macro
  CHECK: No space is necessary after a cast
  CHECK: Alignment should match open parenthesis
  CHECK: Unnecessary parentheses around uniphier_io_policies[image_id].dev_handle

Masahiro Yamada ac9f1b5555 uniphier: support console based on multi-console
The legacy console is gone. Re-add the console support based on the
multi-console framework.

I am still keeping the putc, getc, and flush callbacks in
uniphier_console.S to use plat/common/aarch64/crash_console_helpers.S

The console registration code already relies on that C environment
has been set up. So, I just filled the struct console fields with the
callback pointers, then called console_register() directly. I also
re-implemented the init function in C to improve the readability.

Removing the custom crash console implementation has one disadvantage;
we cannot use the crash console on very early crashes because
crash_console_helpers.S works only after the console is registered.
I can live with this limitation.

Tested on my boards, and confirmed this worked like before.

Antonio Nino Diaz 09d40e0e08 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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("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.
