[U-Boot] Booting armv8 kernel on uboot

[Vishal Bhoj]

Hi ,
I have added mmc driver into the vexpress64 board file for uboot and tested
it on FVP base model. I tried booting a kernel on that but it is aborting
with the following message:
Final value for argc=3
   Loading Kernel Image ... OK
   kernel loaded at 0x00080000, end = 0x00827024
using: FDT
   reserving fdt memory region: addr=80000000 size=10000

Can anyone please provide the procedure on how to boot the kernel with
u-boot on armv8 models ?
