Add support for the BCM2711 Interrupts To allow for better platform support on the Raspberry Pi 4

The year in the license is still 2019. Also, consider using a copyleft license like GNU GPLv3 to disallow nonfree distribution and protect user freedom.

Currently, on x86 we're using multiboot version 1.0. Version 2.0 has more features and should be implemented.

Specification

Add in ability to parse elf headers, to facilitate loading in programs in the future.

Implement the BCM2711's System Timer as a clock source.

Hello, im asking for contact to meet with you about OS Development. If you can reply to me we can talk about this. Thankyou. (For Github Staffs : This is not a silly issue, im asking for contact to participate in github.)

Dear @primis , first of all thank you very much for releasing Apollo OS as a floppy (which could be installed in coreboot/SeaBIOS ROM and booted from there) But before doing that I tried booting your 0.0.2 floppy in QEMU with the following command:
qemu-system-x86_64 -L . -m 256 -fda ./floppy.img -usbdevice tablet -vga vmware -localtime
and only see

GRUB Loading stage2.........
Press 'ESC' to enter the menu... 0

followed by

Booting 'Apollo OS'

root (fd0)
 Filesystem type is fat, using whole disk
kernel /Apollo/sys.mod

and after that QEMU reboots. If there is a way to collect more debug information, please tell me and I will try to provide it

Not sure why my previous issue was closed... Sorry friend but it was not a spam,
I am just trying to find the perfect OS that could fit on a floppy and be quite useful...
Also, it is sad for me to see that your last commit was 1 year ago, perhaps
I could try contributing to your project, but only if it fits on a floppy of course ;)

Even today the floppies are still being used, for example - as virtual floppies inside the coreboot open source BIOS. Just imagine: your wonderful OS could be a part of someone's BIOS build! (for coreboot supported motherboard, maybe you have or could get one - see https://www.coreboot.org/Supported_Motherboards )

If you already have a coreboot-supported motherboard, or a real chance to get one, - wouldn't it be cool to be able to launch your own OS straight from the BIOS chip? ;) With one simple command its possible to add any floppy to coreboot BIOS build - and then you see it as a boot entry! Multiple floppies could be added this way (as long as you have enough space left inside the BIOS flash chip, luckily LZMA compression could be used for the stored floppies to reduce their occupied size)

Add in ability to probe the raspberry pi 4 to see how much memory it has.
This is currently partially stubbed out in src/arch/rpi4/bringup.c at free_memory_get_megs() but requires also ranges to be defined.
