[PATCH v7 3/7] env: Allow U-Boot scripts to be placed in a .env file

[Wolfgang Denk]

Dear Simon,

The cover letter does not mention a separate "env" directory - and
do we really need it?  I will almost always contain just a single
file - so env/<board>.env is an just unnecessary complication.

I feel all these restrictions should also be mentioned in the commit
message, not only in the code.

Best regards,
