Subject: fdt: Limit printed hex in fdt print and list commands
X-Git-Tag: v2013.01-rc1~89^2^2~4
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f0a29d43313c9d0d9091aeae175bd7e8e7ac6124;p=oweals%2Fu-boot.git

fdt: Limit printed hex in fdt print and list commands

Prevent printing the entire image in a itb. It is most likely unhelpful
to have the hex of the entire image scroll for minutes on your slow
serial console.
