Introudce a new function lcdif_power_down.
1. Waits for a VSYNC interrupt to guarantee the reset is done at the
VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?)
and helps the LCDIF work normally at the kernel stage.
2. Add power down function to stop lcdif.
The reason to introduce lcdif_power_down is that we want lcdif to be in
initial state when doing uboot reset or before kernel boot to make
system stable, otherwise system may hang.

The code such as PSCI in section named secure is bundled with
u-boot image, and when bootm, the code will be copied to their
runtime address same to compliation/linking address -
CONFIG_ARMV7_SECURE_BASE.
When compile the PSCI code and link it into the u-boot image,
there will be relocation entries in .rel.dyn section for PSCI.
Actually, we do not needs these relocation entries.
If still keep the relocation entries in .rel.dyn section,
r0 at line 103 and 106 in arch/arm/lib/relocate.S may be an invalid
address which may not support read/write for one SoC.
102 /* relative fix: increase location by offset */
103 add r0, r0, r4
104 ldr r1, [r0]
105 add r1, r1, r4
106 str r1, [r0]
So discard them to avoid touching the relocation entry in
arch/arm/lib/relocate.S.

This change simply deletes code from the Tegra210 XUSB padctl driver that
is already present in the common XUSB padctl code. Since all the arrays
in tegra210_socdata are empty, this update may leave the Tegra210 XUSB
padctl driver non-functional at run-time. However, (a) this driver is not
used yet so no regression can be observed and (b) the next commit will

A fair amount of the XUSB padctl driver will be common between Tegra124
and Tegra210. To avoid cut/paste between the two chips, create a new
file that will contain the common code, and convert the Tegra124 code to
use it. This change doesn't move every last piece of code that can/will be
shared, but rather concentrates on moving code that can be moved with zero
changes, so there are no other diffs mixed in.

Tegra210's PCI controller is largely identical to Tegra124, and hence
shares the same binding. However, it has a unique compatible value due
to the existence of at least one new HW bug that would prevent any driver
for a previous HW version from operating correctly.

This sets up a fine-grained page table, which is a requirement for
noncached_init() to operate correctly.
MMU setup code currently exists in a number of places:
- A version in the core ARMv8 support code that sets up page tables that
use very large block sizes that CONFIG_SYS_NONCACHED_MEMORY doesn't
support.
- Enhanced versions for fsl-lsch3 and zynmq that set up finer grained
page tables.
Ideally, rather than duplicating the MMU setup code yet again this patch
would instead consolidate all the different routines into the core ARMv8
code so that it supported all use-cases. However, this will require
significant effort since there appear to be a number of discrepancies[1]
between different versions of the code, and between the defines/values by
some copies of the MMU setup code use and the architectural MMU
documentation. Some reverse engineering will be required to determine the
intent of the current code.
[1] For example, in the core ARMv8 MMU setup code, three defines named
TCR_EL[123]_IPS_BITS exist, but only one of them sets the IPS field and
the others set a different field (T1SZ) in the page tables. As far as I
can tell so far, there should be no need to set different values per
exception level nor to modify the T1SZ field at all, since TTBR1 shouldn't
be enabled anyway. Another example is inconsistent values for *_VA_BITS
between the current core ARMv8 MMU setup code and the various SoC-
specific MMU setup code. Another example is that asm/armv8/mmu.h's value
for SECTION_SHIFT doesn't match asm/system.h's MMU_SECTION_SHIFT;
research is needed to determine which code relies on which of those
values and why, and whether fixing the incorrect value will cause any
regression.

In order for noncached_init() to operate correctly, SoCs must set up a
custom page table with fine-grained (2MiB) sections, which can be
configured from noncached_init().
This is currently performed by arch/arm/cpu/armv8/{fsl-lsch3,zynqmp}/cpu.c
by cut/pasting and re-implementing mmu_setup, enable_caches(), etc. There
are some other reasons for the duplication there though, such as enabling
icache early, and enabling dcaching earlier with a different configuration.
This change makes mmu_setup() a weak implementation, so that the MMU setup
code can be replaced without having to duplicate other code that calls it.

The implementation of noncached_init() uses define MMU_SECTION_SIZE.
Define this on ARM64.
Move the prototype of noncached_{init,alloc}() to a location that
doesn't depend on !defined(CONFIG_ARM64).
Note that noncached_init() calls mmu_set_region_dcache_behaviour() which
relies on something having set up translation tables with 2MB block size.
The core ARMv8 MMU setup code does not do this by default, but currently
relies on SoC specific MMU setup code. Be aware of this before enabling
this feature on your platform!

In binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbols defined by PROVIDE in
u-boot.lds overrides the linker built-in symbols
(https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;
h=b893397a4b1316610f49819344817715e4305de9),
so the linker is treating _GLOBAL_OFFSET_TABLE_ as a definition into the
.reloc section.
To align with the change of binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbol
should not be defined in sections, and the symbols in linker generated .got
section should be used(https://sourceware.org/ml/binutils/2008-09/

A number of headers define functions as "extern inline" which is
causing problems with gcc5. The reason is that starting with
version 5.1, gcc defaults to the standard C99 semantics for the
inline keyword.
Under the traditional GNU inline semantics, an "extern inline"
function would never create an external definition, the same
as inline *without* extern in C99. In C99, and "extern inline"
definition is simply an external definition with an inline hint.
In short, the meanings of inline with and without extern are
swapped between GNU and C99.
The upshot is that all these definitions in header files create
an external definition wherever those headers are included,
resulting in multiple definition errors at link time.
Changing all these functions to "static inline" fixes the problem
since this works as desired in all gcc versions. Although the
semantics are slightly different (a static inline definition may
result in an actual function being emitted), it works as intended
in practice.
This patch also removes extern prototype declarations for the
changed functions where they existed.
