Date: Sun, 20 May 2018 13:15:37 +0300 From: Dmitry Osipenko <digetx@...il.com> To: Russell King <linux@...linux.org.uk>, Thierry Reding <thierry.reding@...il.com>, Jonathan Hunter <jonathanh@...dia.com> Cc: linux-tegra@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Peter Geis <pgwipeout@...il.com>, Michał Mirosław <mirq-linux@...e.qmqm.pl> Subject: [PATCH v1 0/5] Initial support of Trusted Foundations on Tegra30 Hello, This series of patches brings initial support of Trusted Foundations to Tegra30, that is to the consumer-grade Tegra30 devices which do not allow to easily replace the proprietary bootloader. Support is initial because this series implements only a proper CPU boot-up (main + secondary cores) and a basic L2 cache maintenance that is done using the TF firmware. Suspend-resume support is missing yet as I couldn't get it to work (CPU hangs on resume from suspend after awhile and seems that is related to inappropriately done cache maintenance during of suspend-resume using the firmware), it is work-in-progress for now. This patchset is partially based on the work done by Michał Mirosław [0]. Please review, thanks.
