Any specific reason to use 2MB? u-boot-sunxi-with-spl.bin is only 768KB.

I was shy enough when fine tuning that space. Yes, it fits into 1MB.

[Buildroot] [PATCH 3/5] board/nezha/overlay/boot/extlinux/extlinux.conf: activate framebuffer console on HDMI

[Indrek Kruusa]

Replace serial console with the framebuffer console on HDMI.
Limit resolution to 1280x800 as the framebuffer is really slow.

Why? We generally use serial console in the defconfigs, or at least run
the console and a getty on both the serial port and the video output
like on raspberrypi.

Well, I was thinking that a working HDMI console fits for a wider audience.
But this is subjective indeed. Will take that into account in the future.

Thanks for this patch series, however PATCH 3/5 has apparently not made
its way to the mailing list. Could you double-check?

Thanks!

Thanks. Funny enough I was just working on doing pretty much the same
thing here. I've CC'ed you on the patch series I just sent.

This patch does a bunch of different things, but it doesn't do enough -
E.G. it doesn't update genimage.cfg so the build is broken after this
commit - So that is not good. Maybe have a look at my series where I
update each component (U-Boot/OpenSBI/Linux) separately.

Why still use this custom opensbi? There is D1 support in version 1.1 as
mentioned on https://linux-sunxi.org/Allwinner_Nezha

You are still enabling the old sun20i-d1-spl even though you change to
use U-Boot SPL?

Just in case it helps, I've been testing both the Korsgaard and Kruusa patches on a MangoPI MQ Pro. This board is close, but not exactly like the Nezha, so I expect differences.

Using OpenSBI 1.1 results in a non-booting Linux kernel for me. Here's the error:

```
Unhandled exception: Store/AMO access fault
EPC: 000000005ff8f838 RA: 000000005ffb6346 TVAL: 0000000040040000
EPC: 0000000042e01838 RA: 0000000042e28346 reloc adjusted

Code: b383 0385 be03 0405 be83 0485 bf03 0505 (e110)
```

If I use riscv-software-src/opensbi master, Linux boots again. From my point of view, the Linux Sunxi wiki is correct that forks don't need to be used, but something appears to have been fixed after 1.1.

As a second note, I added the following based on the Sunxi wiki:

BR2_TARGET_OPENSBI_ADDITIONAL_VARIABLES="FW_PIC=y"

It's not clear to me that it makes a difference.

It doesn't seem right for me to add a Tested-By to the patch series since I have a different board. However, the Linux 6.1.0-rc3 update and U-Boot updates appear to be working well in my testing so far. My setup is closer to the Korsgaard patch set since I'm not using the HDMI output change. The OpenSBI issue with 1.1 is the only snag I hit.

Thank you both for your Nezha updates.

-Frank

Nice, then we can prepare support for more boards and test it properly :)
Actually I did my "it boots" testing on Lichee dock. Also known as Lichee
RV dock. The naming of this carrier board or SOM combo is a mess. The
official product is just Lichee dock AFAIK. But none is calling it like
that. Anyway, I can help to prepare support for this board also.

@Angelo Compagnucci <angelo@amarulasolutions.com> , any chance you could
update your Lichee RV patches to the latest "known" goodies? :)

Just to be sure, is this with the 5.19 based kernel we used to use
(fe178cf0153d98b71cb01a46c8cc050826a17e77) or the "new" 6.1-rc3 based
one (ca67838d84af4c9f85d06311c9e98e1adf46308f)?

Sounds like access to an invalid address to me. When does this trigger?
Early doing Linux boot?

I see the mangopi mq-pro only has 512MB RAM. 0x5xxx.xxxx is at the very
end of that (memory starts at 0x4xxx.xxxx), did you update the memory
size in the device tree passed to OpenSBI?

I just did a clean rebuild of nezha_defconfig here, and it boots without
any issues:

I also did a clean build with Peter's patches and the Lichee RV dock is
fine with it. Some snippets from output below. I will drop my patch series
as Peter's series is superior.

I am able to run fine on a 512MB MangoPi MQ-Pro now. This is with the patches that were just merged and with the U-Boot defconfig and Linux DTS witched to the Mango Pi MQ-Pro options. 

I don't have an understanding of the store/AMO access fault above. I had an unintended change to my Linux configuration that just happens to require a later version of OpenSBI. I just wanted to follow up in case anyone stumbles on this thread that the simple U-Boot defconfig and dts switch to the MangoPi versions works.
