Bug #1233
It takes too long to get to the splash screen.
I need to run some bootchart tests again. See RM #472.
See:
# "Instant Pi":https://github.com/IronOxidizer/instant-pi?tab=readme-ov-file discusses methods to boot fast, but there isn't anything to do to speed up the bootloader except maybe boot via a faster SD card.
# "Overclocking Pis":https://www.tomshardware.com/how-to/overclock-any-raspberry-pi
# "Busybox Bootchard":https://elinux.org/Bootchart#BusyBox from elinux.org; this is the way to configure the boot.
bootchard is enabled in the Busybox config so this should be straightforward to run a test.
I will need "pybootchartgui":https://github.com/xrmx/bootchart from bootchart2 to generate the PNG graph. The default bootchartd installed on Debian may have the same tool but it might not work with Busybox's bootchartd.
