I tested this patch and tried to run it on my LicheePi Nano. It works, but I found there is WARNINGs when compile the code:

Ah I will move this it should be moved to defconfig thx for pointing

Not entirely sure how it got defined here, it doesn't get defined in my
generated config.

I have tested the patch on master (pulled 2022-01-20).
licheepi_nano_defconfig compiles and builds just fine for me, and I am
able to run it on the device without incident via FEL mode.

licheepi_nano_spiflash_defconfig however gives me multiple warnings,
and when the warnings are addressed it boots but gives me errors
regarding the SPI controller in U-Boot.

"make licheepi_nano_spiflash_defconfig" warning:
WARNING: unmet direct dependencies detected for SPI_MEM
  Depends on [n]: SPI [=n]
  Selected by [y]:
  - SPI_FLASH [=y]

When I specify CONFIG_SPI=y I get the following when I try to compile:
Environment Sector-Size (ENV_SECT_SIZE) [] (NEW)
When I provide a value of 0x1000 which corresponds to the block size
of the SPI chip I use I then get the following warnings repeated and it
fails to compile:
include/configs/sunxi-common.h:60: warning: "CONFIG_SYS_LOAD_ADDR" redefined

When I work through the remaining errors and get it to compile, I get
this error in U-Boot when attempting to use the SPI controller:
sun4i_spi spi@1c05000: failed to get ahb clock

I presume the issue is that the defconfig is both incomplete for the
SPI booting method and the SUN6I_SPI which is specified in the SPI
defconfig is not in mainline yet.

Until the SPI driver is present it's probably best to just drop the
licheepi_nano_spiflash_defconfig.

Thank you for testing!!

I will be fixing the issues brought up thx for the input.
The issues are DRAM using the device tree.
Clocks in the device tree.
Pinmuxing doesn't work for device tree.
And SPI boot.

Most of the issues im encountering stem from SUNXI being a mix of DT and 
non-DT code. which is frustrating to work with.

Thanks,

Slow depending on application :-)
Two of my customers would like to use it in Q2/Q3 for very low-end HMIs.

And as I see, one of the last F1Cxxx is F1C800s released in 2017. Here 
the good thing they have is ram onboard.

Yes, I'll test on Jesse's board and on Lichee-pi-nano too when I have 
time, this way I'll be able to give a Tested-by: me.

NP!

I took https://github.com/Lichee-Pi/u-boot/tree/nano-v2018.01
re-based it against mainline and fixed formatting in a few files.
I also removed the spi-flash driver as it was causing issues and we can 
boot from sdcard for now. there are some things I did to make the old 
code compatible with new code but mostly preprocessor and configs.

For the dram driver I had to change a bit but none of the logic, i am 
worried that i may have to move it to /drivers.

Do you want a more comprehensive list of changes?

Thanks Icenowy for confirming!

Jesse: yes, it's perfectly fine to send patches from someone else, as
long as you keep the authorship, their SoB, and add your's.
Typical reasons are lack of time or interest from the original author.

But it's customary to ask the author first, and care should be taken
when changing patches, as this might not be in the interest of the
original author (and they are the ones who will get blamed for bugs).
Also please mark the series either as a Resend or as a v2.

So with Icenowy's confirmation above I consider this fine.

But what was actually holding back this series was lack of review,
testing and/or interest. Similar to Icenowy my personal interest in
crufty old cores is somewhat limited, so this wasn't very high on my
priority list.

So given that there is apparently some interest now:
Can you confirm that you have reviewed the series, or at least tested
this? I would be interested to know if a second pair of eyes had a
look, and to what extent. I don't have any hardware, so would need to
rely on others to make sure this code is somewhat sane.

And it basically looks like a v2 of Icenowy's series, so can you give a
Changelog of the differences? I skimmed over her original series back
then, so I would be interested in what makes this version special.

Cheers,
Andre

I got too lazy to send it (because I think F1C100s is just too weak)...

As you are keeping my SoB and adding yours, it's totally okay.

Thanks for cleaning up these patches! ;-)

[PATCH 00/11] Add support for SUNIV and F1C100s.

[Jesse Taube]

This patch set aims to add suport for the SUNIV and F1C100s.
Suport has been in linux for a while now, but not in u-boot.

This patchset contains:
- CPU specific initialization code
- SUNIV dram driver
- SUNIV clock driver adaption
- SUNIV gpio driver adaption
- SUNIV uart driver adaption
- F1C100s basic support

I am hoping to get Icenowy's patches in as it seems she hasnt submitted
in a while. The only edits I made to her code is rebasing it against ML
and changing some formating. I also re-grouped her commits.

I am wondering if the dram driver should be moved into device drivers
rather than in mach-sunxi.
I am also wondering if it is okay to submit some one elses code,
and if so how should I do so.
