Building the Linux kernel and running ROM in QEMU

There is a rather atypical task. In brief, there is the original firmware of the phone, and there is the source code of the kernel of this firmware. The task is to add the necessary parameters to the kernel, specifically for VIRT support. Then, compile the kernel (I can compile the kernel, but for some reason the initramfs does not compile properly. So, it is necessary to compile all of this, and then using the obtained kernel, ramdisk, and device tree blob, run it on QEMU (arm or more likely ARM64).
