2022-12-20eficonfig: carve out efi_get_next_variable_name_int callsMasahisa Kojima
To retrieve the EFI variable name by efi_get_next_variable_name_int(), the sequence of alloc -> efi_get_next_variable_name_int -> realloc -> efi_get_next_variable_name_int is required. In current code, this sequence repeatedly appears in the several functions. It should be curved out a common function.

2022-11-16efi_loader: replace a u16_strdup with alloc + memcpyIlias Apalodimas
Heinrich reports that on RISC-V unaligned access is emulated by OpenSBI which is very slow. Performance wise it's better if we skip the calls to u16_strdup() -- which in turn calls u16_strsize() and just allocate/copy the memory directly. The access to dp.length may still be unaligned, but that's way less than what u16_strsize() would do Signed-off-by: Ilias Apalodimas <[email protected]> Use malloc() instead of calloc().

2022-10-31FWU: Add support for the FWU Multi Bank Update featureSughosh Ganu
The FWU Multi Bank Update feature supports updating firmware images to one of multiple sets(also called banks) of images. The firmware images are clubbed together in banks, with the system booting images from the active bank. Information on the images such as which bank they belong to is stored as part of the metadata structure, which is stored on the same storage media as the firmware images on a dedicated partition. At the time of update, the metadata is read to identify the bank to which the images need to be flashed(update bank). On a successful update, the metadata is modified to set the updated bank as active bank to subsequently boot from.

2022-10-17dm: treewide: Use uclass_first_device_err when accessing one deviceMichal Suchanek
There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch.

2022-10-06efi_loader: define internal implementations of install/uninstallmultipleIlias Apalodimas
A following patch is cleaning up the core EFI code trying to remove sequences of efi_create_handle, efi_add_protocol. Although this works fine there's a problem with the latter since it is usually combined with efi_delete_handle() which blindly removes all protocols on a handle and deletes the handle. We should try to adhere to the EFI spec which only deletes a handle if the last instance of a protocol has been removed. Another problem is that efi_delete_handle() never checks for opened protocols, but the EFI spec defines that the caller is responsible for ensuring that there are no references to a protocol interface that is going to be removed. So let's fix this by replacing all callsites of efi_create_handle(), efi_add_protocol() , efi_delete_handle() with Install/UninstallMultipleProtocol. In order to do that redefine functions that can be used by the U-Boot proper internally and add '_ext' variants that will be used from the EFI API Signed-off-by: Ilias Apalodimas <[email protected]> Reviewed-by: Heinrich Schuchardt <[email protected]>
