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.

around with the cache flush somehow does not work any more now with
the new code change.
To fix this issue, this patch now removes the old workaround and selects
CONFIG_SYS_MALLOC_CLEAR_ON_INIT for ARCH_MTMIPS. With this option the
complete malloc area is initialized with zeros (cache lines are touched).
Testing has shown that this also fixes the issue on the MT7688 boards.

Currently mach-mt7620 contains only support for mt7628. To avoid confusion,
rename mach-mt7620 to mach-mtmips, which means MediaTek MIPS platforms.
MT7620 and MT7628 should be distinguished by SOC_MT7620 and SOC_MT7628
because they do not share the same lowlevel codes.
Dependencies of four drivers are changed to SOC_MT7628 as these drivers
are only used by MT7628.

Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which
represents the start of kseg0 and represents a virtual address. Meaning
that the initrd_start and initrd_end point somewhere kseg0.
When these parameters are passed to linux kernel through DT
they are pointing somewhere in kseg0 which is a virtual address but linux
kernel expects the addresses to be physical addresses(in kuseg) because
it is converting the physical address to a virtual one.
Therefore update the uboot to pass the physical address of initrd_start
and initrd_end by converting them using the function virt_to_phys before
setting up the DT.

In case the ddr training was failing, it couldn't reset, it was just
hanging. Therefore reimplement it, so when ddr training is failing
it would call _machine_restart, which power downs the DDR and does
a force reset.

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.
Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.
With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).
This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

Remove the function boot_reloc_ramdisk in the file arch/mips/lib/bootm
because it is relocating again the ramdisk. The function do_bootm_states()
already relocates the ramdisk even if it is a legacy uImage or a FIT image.
The relocation in the function do_bootm_states() was introduce in the
commit c2e7e72bb9f0cb47d024997b381cb64786eb5402 ("bootm: relocate ramdisk

The x86 dts are switched in a separate commit since it depends on a change

This patch moves all instances of static "watchdog_dev" declarations to
the "data" section. This may be needed, as the BSS may not be cleared
in the early U-Boot phase, where watchdog_reset() is already beeing
called. This may result in incorrect pointer access, as the check to
"!watchdog_dev" in watchdog_reset() may not be true and the function
may continue to run.
