U-Boot with direct NVMe boot support for eMMC/SPI Flash

[mamboman777]

Nah, this has nothing to do with your AUR helper (pamac).
The issue is that Makefile of rkdeveloptool forces GCC to treat all warnings as errors.
Here's the solution:
https://github.com/rockchip-linux/rkdeve.../issues/25

By the way, I updated the repository to use U-Boot v2020.07 and uploaded images for SD/eMMC and SPI.
You can find them on Releases page of the repository.

Thanks for your help.  I'm having a hard time following what to do on the git page.  If I run "make maintainer-clean" I get the message make: *** No rule to make target 'maintainer-clean'. Stop.

I do not understand where to place the code under "Apply the following patch" in the git page.

Thanks again!

Okay, instead of trying to use PKGBUILD, do the following:
- Clone the repository
- Inside the directory,
 - Run "autoreconf -i"
 - Run "./configure"
 - Run "sed -i "s/-Werror//" Makefile" (with quotes before "s" and after the third "/")
 - Run make
You'll find rkdeveloptool binary inside the repo folder.

Thanks for this @pcm720 .  Although I did sucessfully build from your git using  the current u-boot (on ubuntu focal desktop),  I just grabbed your released spiflash.bin and flashed in on current (from unstable) Manjaro.    It's great--boots even faster than it did with the Feb. mainline uboot and atf.  So far I've only booted from my NVME but will test other devices, too.  

A note for other newbies:  Flash_erase is part of the mtd-utils package in arch/Manjaro and one needs to sudo the flash_erase and dd commands if not logged in as root.  

thanks again.

Awesome, thanks for trying it out! Yeah, both commands need to be run with root privileges.
I've added that to release description.

All right. Sitrep. I finally get rkdeveloptool up and running, but it's very unstable on my machine for some reason. I'm guessing that my USB is sleeping within seconds of entering maskrom. So I have to enter the commands almost faster than I can type. I got very good at shorting the correct pins on my SPI. That being said. I was able to get the PBP to boot, but only with an empty SPI. I tried flashing spiflash.bin from within Manjaro running on an SD and using maskrom and neither produced bootable machine. Could it be that something went wrong in the build, I am flashing the wrong "spiflash.bin" (I realized there are more than one last night) or something just doesn't seem whenever I try to flash my SPI? What are my next steps?

Is there a way that someone can get me a properly build "flashspi.bin" to compare to the one I built?  I suspect that's the issue.
