From 7be4706552845824888b58054120dfac99bfdf63 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Mon, 21 Aug 2023 00:40:35 +0100 Subject: unify build/defconfig and modify/defconfig they fundamentally perform the same action: copy the .config file and run make, but build runs make-all, while modify runs make-oldconfig or make-menuconfig merge this functionality together also: ./handle config file ^ this is the new syntax, not: ./build defconfig for for example: ./handle config file -b coreboot x200_8mb <-- build x200 rom ./handle config file -m coreboot x200_8mb <-- modify configs ./handle config file -u coreboot x200_8mb <-- make-oldconfig ./handle config file -u seabios ./handle config file -b u-boot yes, 1 script and a sloccount reduction of 52. and the audit? it continues.
