* m68k: code reformatting for all start.S filesAngelo Dureghello2016-07-30-501/+449
| | | | | | | | | | | | | This patch is style-related only, to reformat all the start.S code, actually not following a coherent style inside single files and between different cpu start.S files. Linux format has been respected, as - max line width at 80 columns - one 8 cols tab between asm instructions and operands - inline comments, where any, fixed at col 41 Signed-off-by: Angelo Dureghello <angelo@sysam.it>
* m68k: add malloc memory for early mallocangelo@sysam.it2016-05-17-37/+147
| | | | | | | | | To use serial uclass and DM, CONFIG_SYS_MALLOC_F must be used. So CONFIG_SYS_GENERIC_GLOBAL_DATA has been undefined and call to board_init_f_mem() is added for all cpu's. Signed-off-by: Angelo Dureghello <angelo@sysam.it> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | The board/freescale/m54418twr/config.mk defined TEXT_BASE, which has the same value as CONFIG_SYS_TEXT_BASE.

* kconfig: switch to KconfigMasahiro Yamada2014-07-30-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables Kconfig. Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

* m68k: Fix incorrect memory access on M5235Vasili Galka2014-07-07-16/+23
| | | | | | | | | | | The csarX and cscrX registers in the fbcs_t struct are 16-bit for CONFIG_M5235 and 32-bit wide otherwise. The code in cpu_init.c accessed them always as 32-bit, effectively creating a wrong memory access on M5235. Fixed that by choosing out_be16/out_be32 depending on whether CONFIG_M5235 is defined or not. Cc: Jason Jin <Jason.jin@freescale.com> Signed-off-by: Vasili Galka <vvv444@gmail.com>

* kbuild: rename OBJTREE to objtreeMasahiro Yamada2014-03-12-3/+3
| | | | | | | | | | | Prior to Kbuild, $(OBJTREE) was used for pointing to the top of build directory with absolute path. In Kbuild style, $(objtree) is used instead.

| | | | | | | | | | | | Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for pointing to the top of source directory. (No difference between the two.) In Kbuild style, $(srctree) is used instead.

* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.
