As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Given gcc-6.1 and later we can now safely have strings discarded when
the functions are unused. This lets us drop certain cases of not
building something so that we don't have the strings brought in when the
code was discarded. Simplify the code now by dropping guards we don't
need now.

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx31
does not boot anymore.
Add a specific relocate_vectors macro that skips the vector relocation, as the
i.MX31 SoC does not provide RAM at the high vectors address (0xFFFF0000), and
(0x00000000) maps to ROM.
This allows mx31 to boot again.

This patch moves mx31 to the common timer functions added in commit
8dfafdd - Introduce common timer functions <Rob Herring>
The (removed) mx31 timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value
cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locks the processor. Rather than patch the specific mx31 issues, simply
move everything over to the common code.

This patch modifies mxcmmc.c to be used
not only by i.MX27 but also by i.MX31 boards.
Both use the same SD controller, but have different
clock set-ups.
The i.MX27 imx_get_XXXclock functions are made static to
generic.c and a public mxc_get_clock() function
is provided. Pins, base address and prototypes for
an i.MX31 specific board_init_mmc() are provided.
Some of the i.MX27 clock getters are unused and marked
as such to avoid warnings (./MAKEALL -s mx27), but
the code was left in for future use.

The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port>
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.

setup_weimcs() and some macros are added to support the setup
for i.MX31 WEIM chip selects. As a compromise between verbosity
and readability an ASCII-art'ish bit comment is used instead of
bitfields.

helper program to verify the changes.

Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes.
Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt
and there was no activity, the system entered into idle mode while watchdog timer was still active.
Fix this by disabling watchdog timer during idle mode.

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
mxc_hw_watchdog_enable
mxc_hw_watchdog_reset
The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the arm1136 timer driver for mx31 and omap24xx
The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

for the armv7/omap-common/timer.c

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
