The 8xx watchdog really is a HW watchdog, so declare it as is
then it goes through Kconfig
And the watchdog reset doesn't mind getting interrupted, so
no need to disable interrupts

Latest versions of u-boot have increased in size and require more
than the 256kb allocated to it.
The MCR3000 board is equipped with an AM29LV160DB boot flash which
is organised as follows:
- One 16kb block
- Two 8kb block
- One 32kb block
- Thirty one 64kb blocks
At the time being, u-boot is a single piece occupying the 256 first
kbytes, then the environment is stored in the following 64kb block
The environment being quite tiny, we save one 64kb block by embedding
the environment in the first 8kb block, hence allowing to increase
the monitor size to 320kb.

Commit 7653942b10 ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
04003df8 g F .text 00000038 mii_init
04004000 g O .text 00000004 env_size
04004004 g O .text 00002000 environment
04006004 g F .text 00000040 .hidden __lshrdi3
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)

The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an
upstream Linux driver in v4.15.
This one uses a slightly different binding from the original one used
by the U-Boot driver.
The differences to the old binding are:
- The "syscon" address is held in a separate node, referenced via a
phandle in the "syscon" property.
- The reference to the PHY is held in a property called "phy-handle",
not "phy".
- The PHY register is at offset 0x30 in the syscon device, not at 0.
- The internal PHY is activated when the node, which phy-handle points
to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node.
Teach the U-Boot driver how to find its resources in a "new-style" DT,
so that we can use a Linux kernel compatible DT for U-Boot as well.
This keeps support for the old binding for now, to allow a smooth
transition.
