2019-06-14efi_loader: fix SetAttribute()Heinrich Schuchardt
The SetAttribute() service and the Reset() service of the simple text output protocol must update the attribute value in the mode information. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: fix SetMode()Heinrich Schuchardt
Correct the check of the mode number in SetMode() service of the simple text output protocol. Clear the screen in SetMode(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: GetTime() must return EFI_UNSUPPORTEDHeinrich Schuchardt
If the GetTime() runtime service is not supported, EFI_UNSUPPORTED has to be returned. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: add RuntimeServicesSupported variableAKASHI Takahiro
This variable is defined in UEFI specification 2.8, section 8.1. Its value should be updated whenever we add any usable runtime services function. Currently we only support SetVirtualAddress() for all systems and ResetSystem() for some. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: parameter checks SetVariable()Heinrich Schuchardt
Return EFI_INVALID_PARAMETER if the variable name has zero length or the variable has runtime access but not boottime access. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: legal characters in StrToFat()Heinrich Schuchardt
The UEFI specification does not specify if the characters that have to be replaced by underscore in function StrToFat() of the Unicode collation protocol are those forbidden in FAT long names or those in FAT short names. EDK2 and UEFI SCT assume it is those forbidden in FAT 8.3 short names. Adjust the list of forbidden characters. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-14efi_loader: MetaiMatch() must be case insensitiveHeinrich Schuchardt

2019-06-12Merge tag 'efi-2019-07-rc5' of git://git.denx.de/u-boot-efiTom Rini
Pull request for UEFI sub-system for v2019.07-rc5 This pull request provides fixes for event services.
2019-06-10efi_loader: implement event queueHeinrich Schuchardt
Up to now we have only been using a flag queued for events. But this does not satisfy the requirements of the UEFI spec. Events must be notified in the sequence of decreasing TPL level and within a TPL level in the sequence of signaling. Implement a queue for signaled events. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-10efi_selftest: correct event group testHeinrich Schuchardt
If any member of the event group is signaled, all members must be set to signaled and their notification functions have to be queued. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-10efi_loader: event signaling in ExitBootServicesHeinrich Schuchardt
ExitBootServices() has to stop timer related activity before calling the events of the EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. But our current implementation was stopping all other events. All events have to observe the task priority level. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-10efi_loader: SignalEvent for event in signaled stateHeinrich Schuchardt
If an event is already in the signaled state, SignalEvent should not queue the notification function but simply return EFI_SUCCESS. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-10efi_loader: RegisterProtocolNotify event signalingHeinrich Schuchardt
In a following patch efi_signal_event() will only queue an event if it is not signaled. Set the is_signaled status to false before signaling the event. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-08Merge branch 'master' of git://git.denx.de/u-boot-tegraTom Rini
The bulk of these changes are an effort to unify Tegra186 builds with builds of prior 64-bit Tegra generations. On top of that there are various improvements that allow data (such as the MAC address and boot arguments) to be passed through from early firmware to the kernel on boot.
2019-06-07lib/vsprintf: allow printing upper case GUIDsHeinrich Schuchardt
In the UEFI context GUIDs are expected to be rendered in upper case. The patch uses the formerly unused bit 1 of the parameter str_format of function uuid_bin_to_str() to indicate if we need upper or lower case output. Function uuid_string() in vsprint.c is adjusted to correctly set the bit depending on the print format code. %pUb: 01020304-0506-0708-090a-0b0c0d0e0f10 %pUB: 01020304-0506-0708-090A-0B0C0D0E0F10 %pUl: 04030201-0605-0807-090a-0b0c0d0e0f10 %pUL: 04030201-0605-0807-090A-0B0C0D0E0F10 Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is concerned by the change. Further patches are needed to adjust the UEFI subsystem. A unit test is provided inside the ut_print command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

Pull request for UEFI sub-system for v2019.07-rc4-2 Support for managing the non-volatile attribute of UEFI variables is added though we do not have a backend for persistence yet. Error messages for changes of UEFI variables are provided. UEFI boottime service implementations are corrected.

2019-06-05fdtdec: Add fdtdec_set_ethernet_mac_address()Thierry Reding
This function can be used to set the local MAC address for the default Ethernet interface in its device tree node. The default interface is identified by the "ethernet" alias. One case where this is useful is for devices that store their MAC address in a custom location. Once extracted, board code can store the MAC address in U-Boot's control DTB so that it will automatically be used by the Ethernet uclass.

2019-06-01efi_loader: open protocol informationHeinrich Schuchardt
When a protocol is opened the open protocol information must be updated. The key fields of the open protocol information records are ImageHandle, ControllerHandle, and Attributes. Consider the Attributes field when determining if an open protocol information record has to be updated or a new one has to be created. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-01efi_loader: correct HandleProtocol()Heinrich Schuchardt
The UEFI specification requires that when a protocol is opened via HandleProtocol() the agent handle is the image handle of the EFI firmware (see chapter on EFI_BOOT_SERVICES.OpenProtocol()). Let efi_handle_protocol() pass efi_root as agent handle to efi_open_protocol(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-01efi_loader: Kconfig entries for GetTime(), SetTime()Heinrich Schuchardt

2019-05-31efi_loader: handling of daylight saving timeHeinrich Schuchardt
If SetTime() is meant to set daylight saving time it will be called with Time.Daylight == EFI_TIME_ADJUST_DAYLIGHT | EFI_TIME_IN_DAYLIGHT. Return 0 from GetTime() if time is not in daylight because we cannot determine if we are in a time zone with daylight saving time. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-05-31efi_loader: check time in SetTime()Heinrich Schuchardt
The UEFI spec prescribes that we check that the timestamp passed to SetTime() is checked for validity. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-05-31efi_loader: correct UninstallProtocolInterface()Heinrich Schuchardt
When uninstalling a protocol the following steps are needed: * request all drivers to disconnect * close protocol for all non-drivers * check if any open instance of the protocol exists on the handle and return EFI_ACCESS_DENIED in this case * remove the protocol interface By tort we tested for remaining open protocol instances already after requesting drivers to disconnect. With this correction the UEFI SCT II tests for UninstallProtocolInterface() and ReinstallProtocolInterface are passed. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-05-31efi_loader: avoid crash in OpenProtocol()Heinrich Schuchardt
When trying to open a protocol exclusively attached drivers have to be removed. This removes entries in the open protocol information linked list over which we are looping. As additionally child controllers may have been removed the only safe thing to do is to restart the loop over the linked list when a driver is removed. By observing the return code of DisconnectController() we can eliminate a loop. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-05-31efi_loader: correct notification of protocol installationHeinrich Schuchardt
When a protocol is installed the handle should be queued for the registration key of each registered event.
