[U-Boot] [PATCH] Don't do an undefined 32-bit shift on a 32-bit value for a long (4 byte) itest.l command.

[Joshua Radel]

Without this fix, the following statement erroneously echoed "true" (at least on the microblaze architecture):
if itest.l 0 == 1; then echo "true"; else echo "false"; fi

(using itest.w or itest.b worked as expected even without this change)
