rtems-tester for raspberry pi 4B

[Noor Aman]

Oh I see, I thought that aarch64/raspberry had the same issue too. Yes, the
aarch64 BSP works fine with the latest firmware. I was able to boot from
USB too. I wanted to setup rtems-tester for aarch64/raspberry BSP using
TFTP/PXE boot, So I needed help with that.
