[U-Boot] Odroid n1- booting hangs if we add memtest=4 to kernel command line.

[Anand Moon]

Hi Jagan / Kever,

I have with me Odroid - N1 per-released development board,
It's almost same form factor to "Firefly-RK3399 Board" with
rk3399-sdram-ddr3-1600.dtsi ram configuration.

I have configure Odroid - N1 board to boot using TPL / SPL configuration
using latest kernel and latest u-boot, but I am facing some issue with not
able to upgrade my distro packages, It's literally hangs on heavy I/O
operations.

So I would like to check if the memory is working correctly, but below
command failed.

# sudo memtester 1024 5
memtester version 4.3.0 (64-bit)

pagesize is 4096
pagesizemask is 0xfffffffffffff000
want 1024MB (1073741824 bytes)
got  1024MB (1073741824 bytes), trying mlock ...

Then I would like to enable *memtest=4* via bootargs ie kernel command
line and it failed to boot up.

below is the logs.

Can you share some input on how to resolve this issue?
or is it I am missing some configuration.
