Add support for OS rollback by enabling the U-Boot environment to be saved in a persistent storage. In this case the environment will be saved in the first boot hardware partition of the eMMC (/dev/mmcblk0boot0). The values of CONFIG_ENV_OFFSET and CONFIG_ENV_SIZE were taken from this tentative patch to U-Boot: https://lore.kernel.org/all/[email protected]/T/ In uEnv.txt.in, the uenv_extra_configs function now runs after check_rollback_needed. This is done so that any auxiliary functions/configs can also be applied during a rollback boot. In fact, this is needed for this board, as uenv_extra_configs executes a function to correct the fdtfile variable and it should always be executed, whether the board is in rollback state or not.

Add initial Torizon OS support for the Texas Instruments AM62P starter kit evaluation module (SK-AM62P-LP). The resulting .wic image file should be flashed to an SD card and the EVM should be configured for SD card boot mode. Related-to: TOR-3725 Signed-off-by: Lucas Akira Morishita <[email protected]>

For AM62x and AM62P Starter Kit EVMs the splash screen wasn't appearing during boot on the HDMI output. Both EVMs use a SiI9022A bridge chip to generate the HDMI signal, so the corresponding driver should be loaded at the same stage where Plymouth is initialized, which is in initramfs in our case. The driver is built and loaded as a kernel module named sii902x. Signed-off-by: Lucas Akira Morishita <[email protected]>
