[PATCH RESEND 0/2] spacemit: k1: SPL robustness for boards without a PMIC or SPI NOR

[Dave Klotz <DaveWK225@protonmail.com>]

Resent: the first posting's cover letter went out with the same
Message-ID as the cover letter of "pci: spacemit: fixes for the K1 PCIe
host driver", so this series threaded under that one. No changes.

Two small SPL changes for K1 boards that do not look like the BPI-F3
and MusePi Pro:

1. pmic_init() and nor_early_init() panic when the device tree gives
   the SPL no PMIC or no SPI controller. A board that boots from eMMC or
   microSD with its rails already up (the OrangePi R2S and RV2) stops
   there. Log it and carry on.
2. Provide board_boot_order(): the device the BootROM booted from, as
   detected now, then the other MMC controller and SPI NOR, so an
   unexpected BootROM path still finds U-Boot.

Tested on an OrangePi RV2 booting from microSD (no SPI controller in
the SPL): "No SPI controller", then the SPL loads U-Boot from the card
through the detected MMC2. The fallback order was not exercised, since
the detection was right.

Dave Klotz (2):
  spacemit: k1: do not require a PMIC or an SPI controller in SPL
  spacemit: k1: fall back to the other boot devices in SPL
