This patch series is related to a parallel patch in Linux: efi: arm/arm64: allow SetVirtualAddressMap() to be omitted https://www.spinics.net/lists/linux-efi/msg15457.html Please, mention it in the next version of the patch series. The Python test_efi_selftest() has to be adjusted: 23 m = u_boot_console.p.expect(['resetting', 'U-Boot']) Please, add the missing patch to the series.
