I have tested the patch on master (pulled 2022-01-20).
licheepi_nano_defconfig compiles and builds just fine for me, and I am
able to run it on the device without incident via FEL mode.

licheepi_nano_spiflash_defconfig however gives me multiple warnings,
and when the warnings are addressed it boots but gives me errors
regarding the SPI controller in U-Boot.

"make licheepi_nano_spiflash_defconfig" warning:
WARNING: unmet direct dependencies detected for SPI_MEM
  Depends on [n]: SPI [=n]
  Selected by [y]:
  - SPI_FLASH [=y]

When I specify CONFIG_SPI=y I get the following when I try to compile:
Environment Sector-Size (ENV_SECT_SIZE) [] (NEW)
When I provide a value of 0x1000 which corresponds to the block size
of the SPI chip I use I then get the following warnings repeated and it
fails to compile:
include/configs/sunxi-common.h:60: warning: "CONFIG_SYS_LOAD_ADDR" redefined

When I work through the remaining errors and get it to compile, I get
this error in U-Boot when attempting to use the SPI controller:
sun4i_spi spi at 1c05000: failed to get ahb clock

I presume the issue is that the defconfig is both incomplete for the
SPI booting method and the SUN6I_SPI which is specified in the SPI
defconfig is not in mainline yet.

Until the SPI driver is present it's probably best to just drop the
licheepi_nano_spiflash_defconfig.
