[U-Boot] [PATCH 8/8] arm: socfpga: Make the pinmux table const u8

[Jian.Luo4 <Jian.Luo4@boschrexroth.de>]

Hi Marek,

the last sed line is invalid for my GNU sed 4.2.2.
Maybe missed a semicolon?

sed -n '/^unsigned/ !b; :next {/^unsigned/ {s/\[.*\]/[]/;s/unsigned long/const u8/};p;n;b next}' \
#                                                       ^here

Best regards,
