Pinetab-V boot rescue

[anoduck]

I managed to bugger up the boot configuration of my pinetab-V. At first, only a blank screen would come up, and it wouldn't even boot into the sdcard, but this much is fixed. 

Now, I want it to boot from the EMMC, which it doesn't do. Luo provides an u-boot update script in the GitHub releases for updating the bootloader, but I do not believe this tool is suited from rescuing the boot of a broken system. 

I will review the starfive documentation on booting, but if someone has experienced a similar issue, assistance would be appreciated. I have some critical projects going on I must dedicate my entire attention to, and cannot afford to tinker as I usually do.

I think I got it, but haven't tested it out yet. The "spl_tool" claims to fix the emmc boot issue if used along with an installation img. It should resolve the problem, but highly likely to overwrite all the work performed to personalize the system. Everything is currently being backed up to salvage as much as possible, and it should take me 56 minutes to download the installation image on my ad-hoc wifi connection.

So, we will see.
