Anyway, the install does in fact succeed, which is great. I probably should have stuck with the LVM partitioning scheme but hey ho, I can re run things now that I know UEFI is working.
So, I have a minimal CentOS install with 4.2.0-0.21.el7.aarch64 kernel. Great start, thanks to all.
There is no networking so I need to get the installer to recognise the nics at install time.
So installer produces a bootable system, complete with a working kernel?
Yes, and no. It produces a bootable kernel.
Right, but how does that kernel get booted? u-boot -> kernel ? u-boot -> UEFI -> kernel ? u-boot -> UEFI -> grub2 -> kernel ?
Does it use grub2 or does it do some magic to boot the kernel straight from UEFI?
I haven't had the nerve to attempt to bun UEFI to SPI-NOR permanently,
Oh, I wasn't suggesting that. I cannot think of a good reason to burn UEFI into SPI-NOR vs. chain-loading it from u-boot, since the boot cascade is automatable.
so following the install (and any subsequent ones) I've loaded it from u-boot manually and then booted directly from UEFI from there. I can of course automate that I suppose.
Right, so post-install the boot process is: u-boot -> UEFI -> kernel ?
No grub2 involved?
The reason I am specifically asking about grub is because grub2 knows how to load the kernel and initramfs off ZFS, and I would prefer to not have to keep /boot on ext4 (even if /boot/efi has to be FAT - because UEFI).
