## 2020-07-31 Standardize USB port power control accross board revisions - BETA
* Turn off USB power power for 1-second regardless of boot-mode. This appears
to resolve an issue on R1.3 and older board revisions where some USB
devices would fail upon reboot. On R1.4 USB port power is turned off
automatically by the PMIC so this is just held in reset for longer. For
earlier board revisions the USB port power is explicitly turned off via
XHCI.
This can be overriden via USB_MSD_PWR_OFF_TIME in the EEPROM config.
* Update the to latest Broadcom memsys FW - no significant functional change.
