Subject: imx: hab: Allow hab_auth_img_or_fail to be called without ivt_offset
X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=2ec9ebc72a432f9b7b6631cb9666245f776cc256;p=u-boot.git

imx: hab: Allow hab_auth_img_or_fail to be called without ivt_offset

Since commit ea91031b2232 ("imx: hab: extend hab_auth_img to calculate
ivt_offset"), it is possible to call the hab_auth_img command without the
last ivt_offset argument.

Currently, calling hab_auth_img_or_fail without the last
ivt_offset parameter causes a failure and the command usage text is shown.

Fix this problem by adjusting the argc logic to allow
calling hab_auth_img_or_fail with only the address and size parameters.

This way, both hab_auth_img and hab_auth_img_or_fail have the same
behavior with respect to the allowed number of command parameters.
