Subject: fix superiotool for NCT6776F
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=coreboot.git;a=commitdiff_plain;h=d35906173ddef192d89532719fbdae29ed232f70

fix superiotool for NCT6776F

The current code exits config mode of the NCT6776F immediately after
detection, so the register dump shows all 0xffs. This patch adds code to
re-enter config mode for the register dump so that the register contents
can be read.
