Usual flow

```

fw -> bootloader -> kernel -> initramfs -> rootfs

```

In its simplest form (no separate initramfs, init included in the kernel)

```

fw -> kernel (init included)

```

No initramfs, separate rootfs

```

fw -> kernel -> rootfs

## How to avoid the need for initramfs

 * build-in kernel modules into the kernel that is needed to mount rootfs (e.g. CONFIG_EXT4_FS=y)

 * set root= kernel command line argument (see https://www.kernel.org/doc/html/v6.4/admin-guide/kernel-parameters.html)
