2014-03-12kbuild: delete redundant LDSCRIPT definitionMasahiro Yamada
$(SRCTREE)/$(CPUDIR)/u-boot.lds is our default location of arch-specific linker script. Remove redundant definitions in arch/{arc,microblaze,openrisc}/config.mk.

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>

2013-07-02avr32/m68k/microblaze/nds32/nios2/openrisc/sh/sparc: fix do_bootm_linuxAndreas Bießmann
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>

2013-03-15Introduce generic link section.h symbol filesSimon Glass
We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-12Refactor linker-generated arraysAlbert ARIBAUD
Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.
