From: Ambroise Vincent Date: Thu, 4 Jul 2019 13:58:45 +0000 (+0100) Subject: arm: Shorten the Firmware Update (FWU) process X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=37b70031e027c76fdebe3c2d2edb2da173bcf150;p=project%2Fbcm63xx%2Fatf.git arm: Shorten the Firmware Update (FWU) process The watchdog is configured with a default value of 256 seconds in order to implement the Trusted Board Boot Requirements. For the FVP and Juno platforms, the FWU process relies on a watchdog reset. In order to automate the test of FWU, the length of this process needs to be as short as possible. Instead of waiting for those 4 minutes to have a reset by the watchdog, tell it to reset immediately. There are no side effects as the value of the watchdog's load register resets to 0xFFFFFFFF. Tested on Juno.
