2021-12-31x86: Allow booting a kernel from the EFI appSimon Glass1-1/+1
At present this is disabled, but it should work so long as the kernel does not need EFI services. Enable it and add a note about remaining work. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-12-31efi: Locate all block devices in the appSimon Glass1-3/+1
When starting the app, locate all block devices and make them available to U-Boot. This allows listing partitions and accessing files in filesystems. EFI also has the concept of 'disks', meaning boot media. For now, this is not obviously useful in U-Boot, but add code to at least locate these. This can be expanded later as needed. We cannot use printf() in the early stub or app since it is not compiled in Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

2021-12-05trace: sandbox: Use only the Kconfig optionsSimon Glass1-7/+2
At present there are Kconfig options for tracing, but sandbox uses plain #defines to set them. Correct this and make the tracing command default to enabled so that this is not needed. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-12-05bloblist: Support allocating the bloblistSimon Glass1-0/+16
Typically the bloblist is positioned at a fixed address in memory until relocation. This is convenient when it is set up in SPL or before relocation. But for EFI we want to set it up only when U-Boot proper is running. Add a way to allocate it using malloc() and update the documentation to cover this aspect of bloblist. Note there are no tests of this feature at present, nor any direct testing of bloblist_init(). This can be added, e.g. by making this option controllable at runtime.

2021-11-07efi: Add video support to the appSimon Glass1-1/+1
The current EFI video driver only works when running in the stub. In that case the stub calls boot services (before jumping to U-Boot proper) and copies the graphics info over to the efi table. This is necessary because the stub exits boot services before jumping to U-Boot. The app maintains access to boot services throughout its life, so does not need to do this. Update the driver to support calling boot services directly. Enable video output for the app. Note that this uses the EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa. A sample qemu command-line for this case is: qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd -drive id=disk,file=try.img,if=none,format=raw -nic none -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0 Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2021-11-07efi: Create a 64-bit appSimon Glass1-3/+3
Most modern platforms use 64-bit EFI so it is useful to have a U-Boot app that runs under that. Add a (non-functional) build for this. Note that --whole-archive causes the gcc 9.2 linker to crash, so disable this for now. Once this is resolved, things should work. For now, avoid mentioning the documentation for the 64-bit app, since it does not work. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2021-11-07efi: Add a script to build an image for testing on UEFISimon Glass1-0/+62
It is quite complicated to run U-Boot on QEMU since we have four different builds and they must use different versions of qemu and the UEFI binaries. Add a script to help. It requires U-Boot itself to be built. Once that is done you can use this script to build an image for use with qemu and optionally run it. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-10-27sandbox: Remove OF_HOSTFILEIlias Apalodimas1-4/+3
OF_HOSTFILE is used on sandbox configs only. Although it's pretty unique and not causing any confusions, we are better of having simpler config options for the DTB. So let's replace that with the existing OF_BOARD. U-Boot would then have only three config options for the DTB origin. - OF_SEPARATE, build separately from U-Boot - OF_BOARD, board specific way of providing the DTB - OF_EMBED embedded in the u-boot binary(should not be used in production Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-10-15pytest: Show a message when sandbox crashesSimon Glass1-0/+8
When a test hands on a real board there is no way on the console to obtain any information about why it hung. With sandbox we can actually find out that it died and get a signal or exit code. Add this to make it easier to figure out what happened. So instead of: test/py/u_boot_spawn.py:171: in expect c = os.read(self.fd, 1024).decode(errors='replace') E OSError: [Errno 5] Input/output error We get: test/py/u_boot_spawn.py:171: in expect c = os.read(self.fd, 1024).decode(errors='replace') E ValueError: U-Boot exited with signal 11 (Signals.SIGSEGV) Signed-off-by: Simon Glass <sjg@chromium.org>

2021-07-24smbios: Fix calculating BIOS Release DatePali Rohár1-1/+0
BIOS Release Date must be in format mm/dd/yyyy and must be release date. U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is generated from current build timestamp. Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is better approximation of U-Boot release date than current build timestamp. Current U-Boot versioning is in format yyyy.mm so as a day choose 01. Some operating systems are using BIOS Release Date for detecting when was SMBIOS table filled or if it could support some feature (e.g. BIOS from 1990 cannot support features invented in 2000). So this change also ensures that recompiling U-Boot from same sources but in different year does not change behavior of some operating systems. Macro U_BOOT_DMI_DATE is not used in other file than lib/smbios.c so remove it from global autogenerated files and also from Makefile.
