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
