Subject: [PATCH 0/3] Add initial support for exynos5420-chagallwifi
Date: Thu, 13 Jan 2022 16:40:16 +0100 [thread overview]
Message-ID: <20220113154019.74434-1-henrik@grimler.se> (raw)
Samsung's tablet Galaxy Tab S 10.5" (wifi) has codename chagallwifi
and is one of several tablets released in 2013 - 2014 based on Exynos
5420. This initial devicetree adds support for accessing device over
USB or UART, and allows using a rootfs in either the internal eMMC or
an external sdcard. 4 out of 8 CPUs are brought up when device boots,
which is the same as on the somewhat similar device
exynos5420-arndale-octa.
Patch 2 is necessary after a secure-firmware node is added, otherwise
device hangs during the CPU1BOOT secure monitor call. Without the
secure-firmware node we are not able to bring up any secondary CPUs.
