From: Heinrich Schuchardt Date: Sat, 16 Jan 2021 08:44:25 +0000 (+0100) Subject: efi_loader: EFI_DEVICE_PATH_UTILITIES_PROTOCOL configurable X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B%20%24style.Permalink%20%7D%7D?a=commitdiff_plain;h=59593a52a3438d163904079ae9c5d4d7c69675bb;p=u-boot.git efi_loader: EFI_DEVICE_PATH_UTILITIES_PROTOCOL configurable 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.
