d96c26040e common: Move clock functions into a new file
These three clock functions don't use driver model and should be migrated.
In the meantime, create a new file to hold them.

941338725d common: Move relocate_code() to init.h
This is an init function so move it out of the common header. Avoid using
the typedef so that we don't have to include the global_data header file.

Also tidy up the function style in comments while we are here.

c30b7adbca common: Move interrupt functions into a new header
These functions do not use driver model but are fairly widely used in
U-Boot. But it is not clear that they will use driver model anytime soon,
so we don't want to label them as 'legacy'.

Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

2a250ae9b6 MIPS: remove Micronas VCT boards
The deadline for migration to CONFIG_DM is v2020.01. The VCT
baords would need an almost complete rewrite of all drivers to
support driver model.

Unless someone has access to the hardware and volunteers to do the migration,
the board should be scheduled for removal.

9814fb272f mips: mt76xx: Implement new d-cache fix in last_stage_init()
With commit 06985289d4 ("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.

f913eab9b9 mips: mt76xx: Remove cache workaround and select SYS_MALLOC_CLEAR_ON_INIT

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.

Dependencies of four drivers are changed to SOC_MT7628 as these drivers
are only used by MT7628.

6943cc9732 arch: mips: Update initrd_start and initrd_end
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.

06985289d4 watchdog: Implement generic watchdog_reset() version
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.

ffd4c7c2ec dts: switch spi-flash to jedec, spi-nor compatible
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

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

ccd063e981 watchdog: Move watchdog_dev to data section (BSS may not be cleared)
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.

344db3f330 mips: add missing dtb-y to arch/mips/dts/Makefile
Since commit 27cb7300ff ("Ensure device tree DTS is compiled"),
build succeeds irrespective of the correctness of Makefile.

In fact, you can compile any defconfig without adding any entry in
arch/*/dts/Makefile.

I am going to revert that commit, so device tree must be explicitly
listed in Makefile.

These misc updates include the following changes:
- Change baudrate from 57600 to 115200
- Enable MIPS_BOOT_CMDLINE_LEGACY
- Enable FIT support
- Enable ethernet support
- Enable SPI support
- Enable GPIO support
- Change max image size from 0x40000 to 0x80000

A note about the baudrate change:

The original Mediatek U-Boot version used 57600 baud. Lets move to a
more common and faster speed of 115200 baud. And remove the "console="
property from the DT as its not needed.

9630146411 MIPS: make size of relocation table fixed but configurable
Currently the size of the relocation table will be shrunk
to the actual size needed. Although this gives a maximal
space saving, it messes up the _end symbol. This breaks
features like appended DTBs because the _end symbol doesn't
point to the real end of the U-Boot binary.

Remove the size shrinking and make the size of the relocation
table fixed but configurable. This follows the Linux approach
and the user can adjust the size to his needs.

Also rename the relocation table section from .rel to .data.reloc
to follow the Linux approach and to avoid ambiguities with the
.rel.* sections added by the linker.
