V3: - Takes addition of function description and makes it a separate patch - Subtracts dangling "uint64_t r" in V2 patch
Heinrich if you want to take this set as is add a SOB to "efi_loader: Add a method description to efi_add_memory_map" and if not please take in my change for "efi_add_runtime_mmio()" to your single patch version. V2: Following on from a discussion with Heinrich Schuchardt, please find a reworked set of patches updating efi_add_memory_map() to - Return efi_status_t - Return EFI_SUCCESS where appropriate - Return EFI_NO_MAPPING in two cases where zero was returned to indicate an error - Updating of users of efi_add_memory_map() to parse for EFI_SUCCESS/efi_status_t I've opted to maintain other returned status codes propogated by functions that call efi_add_memory_map(). For example efi_add_runtime_mmio() continues return EFI_OUT_OF_RESOURCES instead of directly returning the result code of efi_add_memory_map(). The idea being that other users of the EFI layer such as Linux or grub would not be affected by this internal u-boot change. V1: https://patchwork.ozlabs.org/patch/1129402/ https://patchwork.ozlabs.org/patch/1129403/ These two patches fix some inconsistent usage around efi_add_memory_map(). The first patch fixes the case where there is a mapping for an address starting at 0 as is the case on RPI3. We should not print an error for this. efi_add_memory_map(start = 0, ...) succeeds but efi_carve_out_dt_rsv() does not properly parse the result code. The second patch fixes the result code returned by efi_add_memory_map() in two instances. Returing zero is the same as returning EFI_SUCCESS, we should return one of the error codes from include/efi.h only, not zero to indicate failure.
