Set DIB_BOOTLOADER_USE_SERIAL_CONSOLE to false

steveb · steveb · commit cdbd819492da · 2024-06-27T09:05:41.000+12:00
Any console=tty0 or console=ttyS0 arguments can cause latency
regressions in networking. Setting DIB_BOOTLOADER_USE_SERIAL_CONSOLE to
false will prevent any console arguments being added, and will also
remove any console arguments from BLS entries.
