Thanks. 
When SPL_NVME is enabled the build breaks with the following error:
riscv64-unknown-linux-gnu-ld.bfd: disk/part.o: in function
`blk_get_device_part_str':
u-boot/disk/part.c:473: undefined reference to `env_get'
make[2]: *** [u-boot/scripts/Makefile.spl:527: spl/u-boot-spl] Error 1
make[1]: *** [/u-boot/Makefile:2053: spl/u-boot-spl] Error 2

One possible fix is:

if ((!IS_ENABLED(CONFIG_SPL) && IS_ENABLED(CONFIG_ENV_SUPPORT)) ||    
       (IS_ENABLED(CONFIG_SPL) && IS_ENABLED(CONFIG_SPL_ENV_SUPPORT)))
	if (!dev_part_str || !strlen(dev_part_str)
|| !strcmp(dev_part_str, "-"))
	dev_part_str = env_get("bootdevice");
