2015-02-09microblaze: spl: Do not call mem_malloc_init and use early allocMichal Simek
This patch has some parts connected together: - Use _gd in bss section which is automatically cleared Location at SPL_MALLOC_END wasn't cleared at all - Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC (mem_malloc_init is not called at all) - Simplify malloc and stack init. At the end of SPL addr is malloc area and below is stack Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2015-02-09microblaze: Add support for CONFIG_SYS_MALLOC_F_LENMichal Simek
Create space for dm_init where calloc is called and malloc_base has to be initialized. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2015-02-09microblaze: Do not use CONFIG_SYS_GENERIC_GLOBAL_DATAMichal Simek
Because it is not compatible with DM where malloc_base has to be available early and init has to be done in ASM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2015-02-09microblaze: Fix gd_t address which is placed at the end of BRAMMichal Simek
Setup gd from ASM to be availalbe for board_init_r. Setting it up in spl_board_init is too late when MALLOC is used. Space for gd is located behind MALLOC area at the end of BRAM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2014-12-08Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck
Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

2014-10-27kconfig: add CONFIG_SUPPORT_SPLMasahiro Yamada
CONFIG_SPL should not be enabled for boards that do not have SPL. CONFIG_SUPPORT_SPL introduced by this commit should be "select"ed by boards with SPL support and CONFIG_SPL should depend on it. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
2014-09-13kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-09-09microblaze: Fix printf size_t format related warnings (again...)Vasili Galka
The basic idea: Define size_t using the __SIZE_TYPE__ compiler-defined type. For detailed explanation see similar patch for the nios2 arch: "nios2: Fix printf size_t format related warnings (again...)" (sha1: 00a2517fcb5159ed016b25130184638b1dbf2f02) Signed-off-by: Vasili Galka <vvv444@gmail.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
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/.

2014-06-20Makefile: Support include files for .dts filesSimon Glass
Linux supports this, and if we are to have compatible device tree files, U-Boot should also. Avoid giving the device tree files access to U-Boot's include/ directory. Only include/dt-bindings is accessible. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-06-19fdt_support: delete force argument of fdt_initrd()Masahiro Yamada
After all, we have realized "force" argument is completely useless. fdt_initrd() was always called with force = 1. We should always want to do the same thing (set appropriate value to the property) even if the property already exists.

2014-05-12bd_info: remove bi_barudrate member from struct bd_infoMasahiro Yamada
gd->bd->bi_baudrate is a copy of gd->baudrate. Since baudrate is a common feature for all architectures, keep gd->baudrate only. It is true that bi_baudrate was passed to the kernel in that structure but it was a long time ago.

2014-03-04kbuild: fix CROSS_COMPILE settings in config.mkMasahiro Yamada
The syntax CROSS_COMIPLE ?= <cross_compiler_prefix> does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := <cross_compiler_prefix> endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19dts: generate multiple device tree blobsMasahiro Yamada
It is convenient to have all device trees on the same SoC compiled. It allows for later easy repackaging without the need to re-run the make file. - Build device trees with the same SoC under arch/$(ARCH)/dts - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or DEVICE_TREE=... to dts/dt.dtb Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada
Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19dts: re-write dts/Makefile more simply with KbuildMasahiro Yamada
Useful rules in scripts/Makefile.lib allows us to easily generate a device tree blob and wrap it in assembly code. We do not need to parse a linker script to get output format and arch. This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19microblaze: remove an empty file arch/microblaze/lib/time.cMasahiro Yamada
Commit 779bf42c moved timer functions from arch/microblaze/lib/time.c to arch/microblaze/cpu/timer.c. But the empty file, arch/microblaze/lib/time.c has been remaining probably for a human mistake. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Michal Simek <michal.simek@xilinx.com>

Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before calling it again with flag set to BOOTM_STATE_OS_GO. Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will require a complete refactoring later on.

2013-06-26Clarify bootm OS argumentsSimon Glass
At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-05-09gpio: Add support for microblaze xilinx GPIOMichal Simek
Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>
