if i remove the arm,shared-override option in the dts file, the

With the option the kernel boots with the following error:
dmesg --level=err
L2C-310: enabling full line of zeros but not enabled in Cortex-A9
i ve no idea why the parameter have an effect on that. i try
several kernels, allays the same behavior.

Do you use latest u-boot/master or some older version ? Which one?
sorry, i forget it.
i use v2020.01
Should be OK I think. Hmmmmm, I suspect this is another fun with the
ACTLR/CPACR registers, like
937db7188e3a5ab8f802eff9b57854189379667a .
Ley, any ideas ?
I just tested with
2020.07-rc4-00022-gbe79009f3b along with linux v5.7,
and I no longer see the error.
Yes, I also just tested 2020.04 uboot and 5.4.23-lts kernel, also
didn't see this error.
What kernel version you are using?

hello,
i use kernel 4.14.126-rt62-ltsi.
greetings
i try the u-boot version v2020.07-rc4 without the patch,
and everything seems okay, no error at boot.
i ve no idea why the error at boot time is gone with the 2020.07-rc4
version.
does anyone have any idea why?
thanks, greetings
