* [U-Boot] [PATCH] common/cmd_nvedit.c: Fix size calculation in do_env_import()

do_env_import() missed the final '\0' terminator when calculating the
size of an environment data block.  This led to an erroneous 'bad CRC,
import failed' message for a checksum protected environment (-c.)

Can you please describe a test case that shows this bug?

Thanks.

Best regards,

Thanks.

[Note: it would have been even more helpful if you had also provided
a hex dump of "env.bin" - as is, it's difficult for me to see if
there is a bug with cmd_nvedit or with your version of the mkenvimage
tool.]

Best regards,
