board_r: move initr_watchdog to be called after initr_serial
The initr_watchdog is currently placed before initr_serial. The
initr_watchdog calls printf and printf finally calls ops->putc of a serial
driver.
However, gd->cur_serial_dev points to a udevice allocated in board_f. The
gd->cur_serial_dev->driver->ops->putc points the the code region before
relocation.
Some serial drivers call WATCHDOG_RESET() in ops->putc. When DM is enabled
for watchdog, watchdog_reset() is called. watchdog_reset() calls get_timer
to get current timer.
On some platforms the timer driver is also a DM driver. initr_watchdog is
placed right after initr_dm, which means the timer driver hasn't been
initialized. So dm_timer_init() is called. To create a new udevice, calloc
is called.
However start from ops->putc, u-boot execution flow is redirected into the
memory region before relocation (board_f). In board_f, dlmalloc hasn't
been initialized. The call to calloc will fail, and this will cause DM to
print out an error message, and it will call printf again, causing
recursive error outputs.
This patch places initr_watchdog after initr_serial to solve this issue.

mips: mt76xx: Implement new d-cache fix in last_stage_init()
With commit 06985289d452 ("watchdog: Implement generic watchdog_reset()
version") the init sequence has changed in arch_misc_init(), resulting
in a re-appearance of the d-cache issue on MT7688 boards (e.g. gardena).
When this happens, the first (or sometimes later ones as well) TFTP
command hangs and does not complete correctly. This leads to the
assumption that the d-cache is not in a clean state once the ethernet
driver is called (d-cache is used here for the buffers). The old work-
around with the cache flush somehow does not work any more now with
the new code change.
Unfortunately adding CONFIG_SYS_MALLOC_CLEAR_ON_INIT also did not fix
this issue. With v2019.07-rc3 it shows again. The time of accessing
the data seems to be very important here. It needs to be "very late"
in the boot process.
Testing has shown, that copying a 64KiB area in DDR at a very late
bootup time, directly before calling into the prompt, fixes this issue.
Flushing of the complete d-cache does not seem to necessary, as this
copy alone seems to fix this problem.

usb: ehci-mx6: Fix bus enumeration for DM case
The EHCI iMX6 driver is only partly converted to DT probing and
still uses a tremendous amount of hard-coded addresses. Worse,
the driver uses hard-coded SoC-model-specific base addresses, which
are derived from values protected by SoC-specific macros, hence the
driver is also compiled for a specific SoC model. Even worse, the
driver depends on specific sequential indexing of the controllers,
from which it derives offsets in the PHY and ANATOP register sets.
However, when the driver is probed from DT, the indexing is not
correct. In fact, each controller has index 0. This patch derives
the index for DT probing case from the controller base addresses,
which is not the way this should be done, however it is the least
intrusive approach, favorable this close to release.
The necessary steps to convert this driver fully to DT probing are
described inside the patch, however this should be done in the next
release and depends on iMX clock driver patches.

lib: Makefile: build fdtdec_common.c when OF_LIBFDT selected
When build SPL_OF_PLATDATA on i.MX6, meet issue the fdtdec_get_int
not defined, however fdtdec.c will use fdtdec_get_int, so let's
compile fdtdec_common.c when OF_LIBFDT selected.
Since there is also SPL_OF_LIBFDT, so need to use
CONFIG_$(SPL_TPL_)OF_LIBFDT.

pci: Avoid assigning PCI resources that are below 0x1000
commit b7598a43f2b4 ("[PATCH] Avoid assigning PCI resources from
zero address") only moved the bus lower address to 0x1000 if the
given bus start address is zero. The comment said 0x1000 is a
reasonable starting value, hence we'd better apply the same
adjustment when the given bus start address is below 0x1000.
