Old sunxi kernels fail to boot with ARMV7_LPAE enabled.
Any idea why? I don't have relevant stuff with to test this.
I don't know why. It failed to boot linux-sunxi 3.4.104 kernel on A20 OLinuXino-MICRO after updating from 2018.07 to 2018.09-rc1 and would hang at "Starting kernel...".
I bisected the issue to: https://git.denx.de/?p=u-boot.git;a=commit;h=d32e86bde8a31a49cf4a9b233ad91ec...
No problems booting mainline kernel.
Can you update full details of bug on the commit message.
Technically I think the right thing to do would be disabling ARMV7_VIRT as my understanding is that booting into HYP mode doesn't work without LPAE support.
