Subject: Kconfig: define MD5 dependency for FIT support
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=aeb9c53cae09ced27ae246153dcf567ee22fb108;p=project%2Fbcm63xx%2Fu-boot.git

Kconfig: define MD5 dependency for FIT support

FIT images require MD5 support to verify image checksums. So far this
was expressed by defining a CPP symbol in image.h. Since MD5 is now a
first class Kconfig citizen, express that in Kconfig instead.
