Drop second link, not relevant. You are not adding new SoC here, are
you?

No changes against v2? You received comments, didn't you?

Hi Joshua
Many thanks for this update! I'd love to have this board supported in
mainline, and when this happens, I'll add it to Yocto's meta-riscv layer
to make it easy to use.

I managed to boot the board and run tests:
Tested successfully:
* uart0: boot console
* mmc0 (sdhci0?): root filesystem
Issues
*
eth0:
ifconfig eth0 172.24.0.2
[ 48.893725] stmmaceth 4070000.ethernet eth0: Register
MEM_TYPE_PAGE_POOL RxQ-0
[ 48.903077] stmmaceth 4070000.ethernet eth0: cannot attach to PHY
(error: -ENODEV)
ifconfig: SIOCSIFFLAGS: No such device
I believe I have all drivers enabled though...
* emmc:
[ 2.730194] mmc2: Failed to initialize a non-removable card
[ 2.764843] mmc1: Failed to initialize a non-removable card
I tested with a board that has an eMMC
* i2c4: detected by "i2cdetect -l"
but no devices found by "i2cdetect -r 4"
I tried both pins 3/4 and pins 50/48, with two different devices
connected to the bus.
Which pins did you use? I could check the SoC pin muxing, but your
answer will save me time :D
Would you mind sharing your defconfig file ("make savedefconfig") via a
private message or through a link (to avoid sending the entire file to
the list)?
Thanks again
Cheers
Michael.

I realize I replied to the arm64 part of the thread, but indeed I ran my
tests on riscv.
