[PATCH] starfive: visionfive2: switch to standard boot

[E Shattow]

Hi, does this standard boot no longer try to boot from the configured
EFI list? I have a boot listing (for Debian's grub EFI loader)
configured with u-boot eficonfig but it does not seem to be attempting
EFI boot anymore, there is a message about card select error but I
think that must be trying the eMMC (mmc 1) and not the SD Card (mmc
0).

StarFive # mmc list
mmc at 16010000: 0 (SD)
mmc at 16020000: 1

StarFive # help bootflow
bootflow - Boot flows

Usage:
bootflow scan - boot first available bootflow


StarFive # bootflow scan
Card did not respond to voltage select! : -110
No working controllers found
ethernet at 16030000 Waiting for PHY auto negotiation to complete....... done
BOOTP broadcast 1

StarFive # bootefi bootmgr
Card did not respond to voltage select! : -110
Booting: Debian bootloader GRUB
error: no suitable video mode found.
"                                    GNU GRUB  version 2.12-1+b1"...

The documentation for bootflow command seems to have a lot more
options than what I'm seeing now?
