2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2017-07-22powerpc: Remove unneccessary #ifdefs in reginfoChristophe Leroy
reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo() or mpc86xx_reginfo() based on CONFIG_ symbol. As those 3 functions can't me defined at the same time, let's rename them print_reginfo() to avoid the #ifdefs The name is kept generic as it is not at all dependent on powerpc arch and any other arch could want to also print such information. In addition, as the Makefile compiles cmd/reginfo.c only when CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD definition inside a #ifdef CONFIG_CMD_REGINFO Lets all remove the #ifdefs around the U_BOOT_CMD as this file is only compiled when CONFIG_CMD_REGINFO is defined Finally, this is a PowerPC-only command, disable it on a number of non-PowerPC platforms.

2017-05-01fdt: Move fdt_fixup_ethernet to a common placeTom Rini
With 3f66149d9fb4 we no longer have a common call fdt_fixup_ethernet. This was fine to do on PowerPC as they largely had calls already in ft_cpu_fixup. On ARM however we largely relied on this call. Rather than introduce a large number of changes to ft_cpu_fixup / ft_board_fixup we recognize that this is a common enough call that we should be doing it in a central location. Do it early enough that we can do any further updates in ft_cpu_fixup / ft_board_fixup.

This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

2012-11-278xxx: Change all 8*xx_DDR addresses to 8xxxAndy Fleming
There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.
