The following is my operations to install a vanilla CentOS 8.2 aarch64 to raspberry pi 4b.

1.Download uefi firmware
https://github.com/pftf/RPi4/releases/download/v1.18/RPi4_UEFI_Firmware_v1.18.zip
2.Create an SD card in `MBR` mode with a single partition of type `0x0c` (`FAT32 LBA`) or `0x0e` (`FAT16 LBA`). Then format this partition to `FAT`.
3.Extract all the files from the archive onto the partition you created above.
4.Insert the SD card.
------------------------------------------------------------------------
5.Prepare two usb drives.
6.Burn the vanilla CentOS 8.2 aarch64 image to a USB drive1.
7.Plug both USB drives and power up your Raspberry Pi.
------------------------------------------------------------------------
8.Now you will see the install procedure as normal. Please select the USB drive2 as the destiny drive.

Subject: [Arm-dev] Centos 7/8 64 bit on raspberry Pi 3/4
Hello,
 
 
thought I'd check, if there are (not) any plans for a 64 bit Centos
version for the RPI4 (3) ?
 
(there's a 4 core one with 8GB now..  so that would be nice.)
