If any of the arguments contains the sub-string "\c", the line feed is

This does not match shells used in Linux and BSD where the first argument
has to be -n to suppress the line feed.
The hush shell interferes with the parsing of backslashes. E.g. in the
following command line quadruple backslashes are required for suppressing
the line feed:
for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done;

Distro Boot requires a U-Boot-specific script named boot.scr or
boot.scr.uimg which contains boot commands to boot the system. The
boot.cmd is such a file. Use mkimage to generate boot.scr or
boot.scr.uimg from boot.cmd, and the command is:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d boot.cmd boot.scr.uimg
The boot.cmd file is an example script and can be modified based on
needs. bootargs is set in this script and root uses the default value "
/dev/mmcblk1p2 rootwait rw" which can be changed by overriding mmcroot.
