Any idea why? I don't have relevant stuff with to test this. I don't know why.

I bisected the issue to: https://git.denx.de/?p=u-boot.git;a=commit;h=d32e86bde8a31a49cf4a9b233ad91ecdfc96ba2a 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. Some days ago I tried to disable HYP mode for SVC mode. But with SVC the PSCI is not loading (u-boot bug?), and without PSCI only the 1st core of the CPU gets used.
