The first two patches make memtest run ~40x faster (when, as it should
be, dcache is disabled), with the second patch being responsible for
most of that. At least on the beagleboneblack which I used for
testing; other boards and configurations will likely see different
numbers.
This is for CONFIG_SYS_ALT_MEMTEST=y and
CONFIG_SYS_ALT_MEMTEST_BITFLIP=n; one could probably get a similar
improvement in the bitflip case since that also has a schedule() call
in the inner loop.

A function call itself for every word written or read+written in these
loops is bad enough. But since the memory test must be run with dcache
disabled, the schedule() call, traversing the linked list of
registered cyclic clients, and accessing the 'struct cyclic_info' for
each to see if any are due for a callback, is quite expensive. On a
beagleboneblack, testing a modest 16MiB region takes 2.5 minutes:
=> dcache off
=> time mtest 0x81000000 0x82000000 0 1
Testing 81000000 ... 82000000:
Iteration: 1
Tested 1 iteration(s) with 0 errors.
time: 2 minutes, 28.946 seconds
There is really no need for calling schedule() so frequently. It is
quite easy to limit the calls to once for every 256 words by using a
u8 variable. With that, the same test as above becomes 37 times
faster:
=> dcache off
=> time mtest 0x81000000 0x82000000 0 1
Testing 81000000 ... 82000000:
Iteration: 1
Tested 1 iteration(s) with 0 errors.
time: 4.052 seconds
Note that we are still making a total of
3 loops * (4 * 2^20 words/loop) / (256 words/call) = 49152 calls
during those ~4000 milliseconds, so the schedule() calls are still
done less than 0.1ms apart.
These numbers are just for a beagleboneblack, other boards may have a
slower memory, but we are _two orders of magnitude_ away from
schedule() "only" being called at 100Hz, which is still more than
enough to ensure any watchdog is kept happy.

It is obviously important that the addr pointer used to access the
memory region being tested is volatile-qualified, to prevent the
compiler from optimizing out the "write this value, read it back,
check that it is what we expect".
However, none of these auxiliary variables have any such need for,
effectively, being forced to live on the stack and cause each and
every reference to them to do a memory access.
This makes the memtest about 15% faster on a beagleboneblack.
Before:
=> dcache off
=> time mtest 0x81000000 0x81100000 0 1
Testing 81000000 ... 81100000:
Iteration: 1
Tested 1 iteration(s) with 0 errors.
time: 10.868 seconds
After:
=> dcache off
=> time mtest 0x81000000 0x81100000 0 1
Testing 81000000 ... 81100000:
Iteration: 1
Tested 1 iteration(s) with 0 errors.
time: 9.209 seconds
[Without the 'dcache off', there's no difference in the time, about
0.6s, but the memtest cannot usefully be done with dcache enabled.]

Exynos850 SoC has a dual-role USB controller which can be configured in
USB host role. As it's the only one USB controller on the board, it's
shared between "device" USB connector (micro-USB) and host USB
connectors. The hardware automatically powers on the host related parts
when the micro-USB cable (for device role) is being disconnected. Also,
as U-Boot lacks dynamic USB role switching capability, the only way to
switch the role at the moment is to modify "dr_mode" property in
U-Boot's device tree file here:
dts/upstream/src/arm64/exynos/exynos850-e850-96.dts
This won't affect the dynamic role switching later in Linux kernel, as a
separate (different) device tree blob is provided to the kernel.

Linux kernel should use some separate device tree obtained from another
source anyway. For example the dtb file can be read from /boot directory
in eMMC rootfs partition, either by GRUB or U-Boot. Using U-Boot's
device tree blob to provide it to the kernel (when
CONFIG_DEFAULT_FDT_FILE is set and nobody else overrides this choice)
might lead to undesired effects when booting the OS. For example, if a
user sets "dr_mode" property to "host" value in U-Boot's dts to enable
USB host capabilities in U-Boot, it might confuse usb-conn-gpio driver
in Linux kernel later like this:
platform connector: deferred probe pending: usb-conn-gpio:
