Subject: package/uboot-tools: add option to install fit_check_sign
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b026d97ed8a3916e9e00584db6a0ded847e0c3b1;p=buildroot.git

package/uboot-tools: add option to install fit_check_sign

This commit adds an option to install fit_check_sign to target for fit
image validation.

This will allow a fit image to have its signature and hashes validated
from Linux, assuming a device-tree of keys (the same as which is in
u-boot) is available.
