Advanced users • Diagram of the boot sequence for Rapsberry pi 4

Hi I'm following my previous post

I try to understand the boot sequence and the files linked to all of the those steps.

Here my supposition, please correct me.


1. Bootloader
located in the Broadcom ROM (can we update it and how ?)
it look for <a file> on the first bootable medium (here sdcard ) and load in memory (initramfs)

2. initramfs
aka firmware ?

3.Kernel Loading
when the initramfs has finish, the Bootloader search for the Kernel in the bootable medium ? and launch it in memory

4. Kernel boot

5.init boot

If you have also any resources, diagram etc.. I'm all ears

Thanks.

There is also the /boot/config.txt But I don't know where it take place in the sequence ?
