This patch series is the final proposal from Aneesh and myself for a generic SPL framework. The implementation already works and have been tested with in-tree and out-of-tree builds. The latest feedback from ML is already included.
How it works
There is a new directory TOPDIR/spl which contains only a Makefile. All source files needed by SPL are recompiled inside this directory and linked to the final binaries named u-boot-spl[.bin|.map].
During the SPL build a variable named CONFIG_SPL_BUILD is exported in the make environment and also appended to CPPFLAGS with -DCONFIG_SPL_BUILD. Thus makefiles and source files are able to build things differently for SPL.
Config options
CONFIG_SPL Enable building of SPL globally.
CONFIG_SPL_TEXT_BASE TEXT_BASE that is used when linking the SPL binary.
CONFIG_SPL_GC_SECTIONS Optionally enforce garbage collecting of sections for SPL. Useful if this is not yet fully supported by ARCH, CPU or SOC
CONFIG_SPL_LIBCOMMON_SUPPORT CONFIG_SPL_LIBDISK_SUPPORT CONFIG_SPL_I2C_SUPPORT CONFIG_SPL_GPIO_SUPPORT CONFIG_SPL_MMC_SUPPORT CONFIG_SPL_SERIAL_SUPPORT CONFIG_SPL_SPI_FLASH_SUPPORT CONFIG_SPL_SPI_SUPPORT CONFIG_SPL_FAT_SUPPORT CONFIG_SPL_LIBGENERIC_SUPPORT Enable building and linking of common libraries and drivers into the SPL binary.
Aneesh V (3): arm: adjust PLATFORM_LIBS for SPL scaled down version of generic libraries for SPL replace CONFIG_PRELOADER with CONFIG_SPL_BUILD
Daniel Schwierzeck (6): Use ALL-y style instead of ifeq blocks for better readability spl: add initial support for a generic SPL framework Extend build-system for SPL framework Hook SPL build-system into toplevel Makefile spl: Add support for common libraries and drivers spl: add support for omap-common libraries
