| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to now, there are 3 kind of SoCs under Layerscape Chassis 2, like LS1043A, LS1046A and LS1012A. But the clocks tree has a lot of differences, for instance, the IP modules have different dividers to derive its clock from Platform PLL. And the core cluster PLL and platform PLL maybe have different reference clocks, such as LS1012A. Another problem is which clock/PLL should be described by sys_info->freq_systembus, it is confused in Layerscape Chissis 2. This patch is to bind the sys_info->freq_systembus to the Platform PLL, and handle the different divider of IP modules separately between different SoCs, and separate reference clocks of core cluster PLL and platform PLL.

The SMPEN bit should be set before enabling the data cache. If not enabled, the cache is not coherent with other cores and data corruption could occur. For A57/A72, SMPEN bit enables the processor to receive instruction cache and TLB maintenance operations broadcast from other processors in the cluster.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bb5930d5c97f ("exynos: video: Convert several boards to driver model for video") converted the Exynos Chromebooks machines to use DM for video, but this breaks backward compatibility with the stdout env var since now stdout is expected to be "vidconsole" instead of "lcd". This causes display to not work when updating u-boot on these boards if the old stdout env var is used. Since these are consumer devices, there's no easy way to have a serial console so users may be confused thinking that u-boot failed to boot, or in the best case will need to update the stdout env var blindly to make the display to work again. There's a CONFIG_VIDCONSOLE_AS_LCD config option to workaround this, so enable it in the Chromebooks' default configuration files to allow users to change their stdout env var before the workaround is removed.
