Hi Vagrant, thanks for looking at this.

Great. I've tried making that change to debian/targets in version
2021.01+dfsg-1 (patch is below) and rebuilding, and I've verified that
for all eleven arm64 sunxi platforms:
- u-boot-sunxi-with-spl.bin is equal to spl/sunxi-spl.bin concatenated
with u-boot-sunxi-with-spl.fit.fit
- spl/sunxi-spl.bin is 32K in size
- u-boot-sunxi-with-spl.fit.fit differs from u-boot-sunxi-with-spl.fit.itb
only in a timestamp
Therefore, for each of these platforms, writing u-boot-sunxi-with-spl.bin
to the card at offset 8K should work just as well as writing the SPL at
8K and the FIT image at 40K, which the current u-boot-install-sunxi
script does. I've confirmed that it works on the Orange Pi One Plus.

I saw that version, thanks, but I was proposing to further simplify the
script by making it write just one file to the card rather than two.
I've double-checked and I'm sure my patch to that script doesn't
duplicate any changes already made. The full list of changes in the
patch is:
- Improve 'Specify target' error message
- Remove check for mkimage which is no longer used
- Avoid creating tempfiles in current directory
- Write one combined file to card rather than two components
- Sync on the write operation rather than separately

OK. What do you think of the idea of installing it only where needed?
Perhaps it could be listed explicitly in debian/targets for those
platforms that require it.
Thanks very much,
Harold.
