========================================================= The purpose of the BSP patch is to allow building several boards inside the same buildroot tree. For this to work, each board has to have its own "$(TARGET_DIR)" and all *configurable* packages must be rebuilt for each board. They are now built in the "$(PROJECT_BUILD_DIR)" All non configurable packages can and should still be built in the "$(BUILD_DIR)". If a package is built for one board, then when you build for a second board of the same architecture the build becomes a simple copy of the resulting binaries. ----- Define BR2_PROJECT which will be used as the selector between different boards. Note that BR2_PROJECT allow you to build multiple root file systems for a single board, and should not be confused with BR2_BOARD_NAME which relates to the H/W. ----- Define PROJECT_BUILD_DIR as "PROJECT_BUILD_DIR/$(PROJECT)" Define BINARIES_DIR as "binaries/$(PROJECT)" Define TARGET_DIR as "$(PROJECT_BUILD_DIR)/root" (some prefix/postfix may apply) Resulting images are stored in "$(BINARIES_DIR)" ----- Define a few new environment variables in Makefile PROJECT: Stripped BR2_PROJECT DATE: Date of build in YYYY-MM-DD format HOSTNAME: Stripped BR2_HOSTNAME => /etc/hostname BANNER: Stripped BR2_BANNER => /etc/issue Linux and Busybox will be built in $(PROJECT_BUILD_DIR) More patches will be needed later to ensure all configurable packages are built in this directory.
