'os-tutorial: porting from x86_64 to ARM Cortex A9

For learning purpose I started this series of tutorials about writing an operating system from scratch: os-tutorial

The tutorial aims at x86_64 systems using NASM assembler. My goal is to translate the code in order to execute it on ARM systems using arm-none-eabi-as as the assembler. I understand the x86_64 code provided in the tutorial but I am struggling in the translation step.

Are there any resources that could help me with the task?

For example, how can I translate the following x86_64 code in ARM?

mov ah, 0x0e ;tty mode
mov al, 'H'
int 0x10
mov al, 'e'
int 0x10
mov al, 'l'
int 0x10
int 0x10
mov al, 'o'
int 0x10

loop:
    jmp loop ;infinite loop

times 510-($-$$) db 0 ;write 510 minus previous code size 0

dw 0xAA55 ;write an half word -- boot magic number
