From: Simon Glass Date: Wed, 28 May 2025 16:03:14 +0000 (-0600) Subject: efi: Rename the lib/efi directory X-Git-Tag: v2025.10-rc1~7^2~10 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ea957952362fe9238cbf3996c001f8bf3f04701;p=thirdparty%2Fu-boot.git efi: Rename the lib/efi directory This directory was created when U-Boot gained the ability to run as an EFI app in 2015. Since then the EFI-loader feature has been added. The code in lib/efi is not actually used by the loader, so the name is confusing. Rename the directory to efi_client to indicate that it includes files just for U-Boot being a client of EFI, i.e. the EFI app and stub.
