* b/assets: use different kernel command line for arm64 Do not set console in the kernel command line for arm64. The defaults are better than setting ttyS0 as in x86, also this is our choice in server images. The kernel will choose the preferred console depending on whether dtb or ACPI is available: 1. When having a device tree, it will take the content of the /chosen/stdout-path node [1]. This node is properly filled in most of the cases. 2. If using ACPI tables, it will look for the console in the ACPI SPCR table [2,3]. This is different to what is done in x86 [4], as in that case the SPCR table is used only if earlycon is set.
