[U-Boot] Regarding HUSH support in uboot

[amruth vamadev]

Wolfgang Denk
Thanks for response.If I want to store those strings into variable and
may be compare it or parse it for information.For example "echo a"
redirected to variable like assignment. My goal is to write simple
diags to test pci or serial flash using commands in the shell using
script. We can issue the commands and parse the response and print
useful messages to users.
myvar = echo a
if itest.s myvar == a
then echo 'a"
else echo "no a"
Any idea how we can achieve this.
Thanks
Amruth p.v
