efi_loader: disable GRUB_ARM32_WORKAROUND on ARCH_SUNXI

2021-03-16T08:37:04Z

GRUB_ARM32_WORKAROUND can be disabled on ARCH_SUNXI as the Allwinner SoCs only have a level 2 cache controlled via CP15 and not an architecturally defined cache. Having the cache available speeds up booting Linux. On ARCH_BCM283X it is already disabled via rpi_2_defconfig. But let's move this setting to Kconfig. Signed-off-by: Heinrich Schuchardt

efi_loader: remove EFI_UNICODE_COLLATION_PROTOCOL

2021-01-20T07:17:17Z

In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2 language codes existed. This protocol is not part of the UEFI specification any longer. It was however required to run the UEFI Self Certification Test (SCT) II, version 2.6, 2017. So we implemented it for the sole purpose of running the SCT. As the SCT does not need the protocol anymore it is time for removal. Signed-off-by: Heinrich Schuchardt

efi_loader: EFI_DEVICE_PATH_UTILITIES_PROTOCOL configurable

2021-01-20T07:17:17Z

Allow the EFI_DEVICE_PATH_UTILITIES_PROTOCOL to be disabled via configuration. On systems that are very tight on U-Boot image size we may want to disable the protocol. As it is required to run the UEFI Shell enable it by default. Signed-off-by: Heinrich Schuchardt

efi_loader: make EFI_DT_FIXUP_PROTOCOL configurable

Allow EFI_DT_FIXUP_PROTOCOL to be disabled via configuration. Signed-off-by: Heinrich Schuchardt

efi_loader: make the UEFI boot manager configurable

2021-01-20T07:09:34Z

Some boards are very tight on the binary size. Booting via UEFI is possible without using the boot manager. Provide a configuration option to make the boot manager available. Signed-off-by: Heinrich Schuchardt

efi: capsule: Add support for uefi capsule authentication

2020-12-31T13:41:31Z

Add support for authenticating uefi capsules. Most of the signature verification functionality is shared with the uefi secure boot feature. The root certificate containing the public key used for the signature verification is stored as part of the device tree blob. The root certificate is stored as an efi signature list(esl) file -- this file contains the x509 certificate which is the root certificate. Signed-off-by: Sughosh Ganu

efi_loader: make variable store size customizable

2020-12-31T13:27:41Z

Currently the size of the buffer to keep UEFI variables in memory is fixed at 16384 bytes. This size has proven to be too small for some use cases. Make the size of the memory buffer for UEFI variables customizable. Reported-by: Paulo Alcantara (SUSE) Signed-off-by: Heinrich Schuchardt Acked-by: Ilias Apalodimas

sandbox: implement runtime system reset

2020-12-23T03:39:25Z

Implement a reset function that we can call after ExitBootServices(), when all driver model devices are gone. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

efi_loader: add firmware management protocol for raw image

2020-12-03T20:22:50Z

In this commit, a very simple firmware management protocol driver is implemented. It will take a binary image in a capsule file and apply the data using dfu backend storage drivers via dfu_write_by_alt() interface. So "dfu_alt_info" variable should be properly set to specify a device and location to be updated. Please read README.dfu. Signed-off-by: AKASHI Takahiro

efi_loader: add firmware management protocol for FIT image

2020-12-03T20:22:50Z

In this commit, a very simple firmware management protocol driver is implemented. It will take a common FIT image firmware in a capsule file and apply the data using dfu backend storage drivers via update_fit() interface. So "dfu_alt_info" variable should be properly set to specify a device and location to be updated. Please read README.dfu. Fit image is a common file format for firmware update on U-Boot, and this protocol works neatly just as a wrapper for one. Signed-off-by: AKASHI Takahiro
