The year 2038 problem in rtc_to_tm() is reusing code from Linux.
The EFI runtime service GetTime() is used to read the time form the real time clock.
The RTC drivers are made usable even if U-Boot is built without CONFIG_CMD_DATE.
The implementation of the GetTime() runtime service is corrected.
v2: do not support non-driver-model drivers
Heinrich Schuchardt (6): drivers: rtc: resolve year 2038 problem in rtc_to_tm rtc: remove CONFIG_CMD_DATE dependency efi_loader: remove unused efi_get_time_init() efi_loader: complete implementation of GetTime() efi_selftest: support printing leading zeroes efi_selftest: unit test for GetTime()
