include: configs: am62x_evm: Add android bootflow
Add android boot flow support for AM62X board based on misc partition to detect reboot reason and boot.img version 2 from android build system. Also add device tree overlay support for Android to enable CSI camera, LVDS screen, HDMI Audio output. This assumes that the `dtbo_index` env variable is a space-separated list of indices. Example: => env set dtbo_index "0 2" => run distro_bootcmd Signed-off-by: Guillaume La Roque <glaroque@baylibre.com> [mkorpershoek: move parts to am62x.env file] Co-developed-by: Mattijs Korpershoek <mkorpershoek@baylibre.com> Signed-off-by: Mattijs Korpershoek <mkorpershoek@baylibre.com>
