+ Simon, could you review this change? It would be nice to have this fix in 
upcoming U-Boot release.

When having environment stored in EXT4 or FAT
and using an AHCI or SCSI device / partition
the scan would not be performed early enough
and hence the device would not be recognized.
This change adds the scan when the interface
is "scsi" in a similar way to mmc_initialize.

While running some CI tests, this error occurs with this patch:

$ make dra7xx_hs_evm_usb_defconfig
...
$ make -s -j20
...
/opt/kernel.org/gcc-11.1.0-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld.bfd: env/fat.o: in function `env_fat_load': /home/stefan/git/u-boot/u-boot-marvell/env/fat.c:134: undefined reference to `scsi_scan'
make[1]: *** [scripts/Makefile.spl:512: spl/u-boot-spl] Error 1
make: *** [Makefile:2101: spl/u-boot-spl] Error 2

Could you please take a look? And send a fixed version which also
passed a "world build" for all supported targets?

Thanks,
Stefan
