Subject: binman: Generate an error when text is not provided
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0b489364f90d5cd70b594268442b14e0143c89b5;p=project%2Fbcm63xx%2Fu-boot.git

binman: Generate an error when text is not provided

When the value of a text entry is not provided an execption is generated
talking about a None type. This is confusing. Add a more explanatory error
and a test for this case.
