Log:
OLPC - add support for not rebooting on tag change on XO-1.75 and XO-4.  This used to be  ' noop to spi-reprogrammed , but this was broken with the addition of CP and AP tag support in XO-1.75.  Manufacturing scripts use ($add-tag) and ($delete-tag) followed by (put-mfg-data) and so bypass this already.  #12578.
