Hi all,

This patch series fixes 2 bug in the boot code for the memory management.

The first patch should resolve Xen stall when setting SCTLR.XN on some
platforms.

The second patch should allow to boot Xen again the Hikey board.

Cheers,

Hi Julien,

These patches fix my Hikey960 problems - I'm able to boot all expected
CPUs without trouble now.

Feel free to add

Thanks for the good work!
