efi_loader: incorrect return value form DisconnectController

2019-09-20T18:09:18+00:00

DisconnectController() should never return EFI_NOT_FOUND.
If EFI_DRIVER_BINDING_PROTOCOL.Stop() fails, return EFI_DEVICE_ERROR.

If the driver handle does not expose the EFI_DRIVER_BINDING_PROTOCOL
return EFI_INVALID_PARAMETER.

efi_loader: re-enable GRUB workaround on 32bit ARM

2019-07-30T19:36:22+00:00

GRUB on ARM 32bit prior to version 2.04 lacks proper handling of caches.
In U-Boot v2019.04 a workaround for this was inadvertently removed.

The workaround is currently also needed for booting on systems with caches
that cannot be managed via CP15 (e.g. with an i.MX6 CPU).

Re-enable the workaround and make it customizable.

efi_loader: detach runtime in ExitBootServices()

2019-07-06T19:25:32+00:00

Linux can be called with a command line parameter efi=novamap, cf.
commit 4e46c2a95621 ("efi/arm/arm64: Allow SetVirtualAddressMap() to be
omitted"). In this case SetVirtualAddressMap() is not called after
ExitBootServices().

OpenBSD 32bit does not call SetVirtualAddressMap() either.

Runtime services must be set to an implementation supported at runtime
in ExitBootServices().

efi_loader: let the variable driver patch out the runtime

2019-07-06T19:25:32+00:00

Our variable services are only provided at boottime. Therefore when
leaving boottime the variable function are replaced by dummy functions
returning EFI_UNSUPPORTED. Move this patching of the runtime table to the
variable services implementation. Executed it in ExitBootServices().

efi_loader: remove NULL entries from runtime detach list

2019-07-06T19:25:32+00:00

Some entries in the system table are set to NULL in ExitBootServices(). We
had them in the runtime detach list to avoid relocation of NULL. Let's
instead assign the pointers dynamically in efi_initialize_system_table() to
avoid the relocation entry.
