Subject: board:tricorder: always work with valid eeprom data
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1ea2301fcfbfc85e38eb51e1144c5ac190c4c320;p=project%2Fbcm63xx%2Fu-boot.git

board:tricorder: always work with valid eeprom data

Commit 890880583d84607e36b52a785a96b167728bbf73 introduced EEPROM parsing and
board detection but faild to return a valid tricorder_eeprom struct for backup
case.  When pressing S200 while reading EEPROM we ignore the value. We
returned falsely a tricorder_eeprom struct with uninitialized data which is
just garbage.
Initialize it by zeroing the whole structure.
