1 ) Note: bootargs is over 480 characters long
setenv abc $bootargs fails...when bootargs is over 350 (approx) characters
long.
fdt set bootargs /chosen bootargs
fdt get value bootargs /chosen bootargsbootargs=8250.nr_uarts=0Bootargs is
truncated
The PI firmware generated bootargs parameters have blanks in the bootargs line.
nvalue.c implements setenv in the _do_env_set() routine, but I cannot find a
length limit in that routine.
I'm willing to make the changes and test them.
Thanks Duncan
