ELBERT: Enable Alternate boot (#108)
d66b89a 
Summary:
ELBERT: Enable Alternate boot

- Enable WDT2 by default in U-boot
- Make elbert U-boot more consistent with other AST2620 platforms
- Add disable_watchdog.sh to disable WDT2 after kernel boot
- Add boot_info.sh to view and set the boot source

Testing:

root@bmc-oob:~# boot_info.sh
Usage:
     boot_info.sh <bmc> reset <primary|secondary>

     Examples:
      boot_info.sh bmc
      boot_info.sh bmc reset secondary

      root@bmc-oob:~# boot_info.sh bmc
      WDT1 Timeout Count:  0
      WDT2 Timeout Count:  0
      Current Boot Code Source: Primary Flash
      root@bmc-oob:~# cat /etc/version
      20201105194531

      root@bmc-oob:~# boot_info.sh bmc reset primary
      Current boot source is primary, no need to switch.

      root@bmc-oob:/mnt/data1# boot_info.sh bmc reset secondary
      BMC will switch to secondary after 2 seconds    ...
      # boot

      root@bmc-oob:~# boot_info.sh bmc
      WDT2 Timeout Count:  3
      Current Boot Code Source: Secondary Flash
      root@bmc-oob:~# boot_info.sh bmc reset secondary
      Current boot source is secondary, no need to switch.
      root@bmc-oob:~# boot_info.sh bmc reset primary
      BMC will switch to primary after 2 seconds    ...

soft reboot kept BMC booting from slave
 wedge_power.sh reset returned BMC to master

NOTE: The secondary spi flash must have a version containing this uboot otherwise the automatic switchover will go back to primary. I recommend upgrading all units to have at lease this change in secondary flash.
