fdt: nios: Fix warning in ft_cpu_setup()

2015-04-10T14:15:24Z

This function should not return a value. Signed-off-by: Simon Glass Acked-by: Thomas Chou

generic-board: select SYS_GENERIC_BOARD for some architectures

2015-03-28T13:03:08Z

We have done with the generic board conversion for all the boards of ARC, Blackfin, M68000, MicroBlaze, MIPS, NIOS2, Sandbox, X86. Let's select SYS_GENERIC_BOARD for those architectures, so we can tell which architecture has finished the conversion at a glance.

generic-board: move __HAVE_ARCH_GENERIC_BOARD to Kconfig

2015-03-28T13:03:08Z

Move the option to Kconfig renaming it to CONFIG_HAVE_GENERIC_BOARD. Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass Reviewed-by: Alexey Brodkin

Kbuild: introduce Makefile in arch/$ARCH/

2014-12-08T14:35:45Z

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.

fdt: Allow ft_board_setup() to report failure

2014-11-21T03:43:15Z

This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later. Signed-off-by: Simon Glass Acked-by: Anatolij Gustschin

kconfig: remove redundant "string" type in arch and board Kconfigs

2014-09-13T20:43:55Z

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

nios2: link to CONFIG_SYS_MONITOR_BASE and remove text_base hook

2014-08-30T09:48:43Z

This patch changes the link script to base at CONFIG_SYS_MONITOR_BASE. Then we can remove the text_base hook in nios2-generic board. Signed-off-by: Thomas Chou

nios2: move nios2.h to arch asm directory

2014-08-30T09:48:43Z

The nios2.h is nios2 cpu specific, and should go arch asm directory. Signed-off-by: Thomas Chou

nios2: divide nios2-io.h into each specific drivers and remove it

2014-08-30T09:48:43Z

The nios2-io.h defines hardware registers and bits of several FPGA IP cores. It could be divided in to the specific drivers, including altera timer, altera sysid, altera uart and altera jtag uart. The altera pio and altera spi drivers use their own hardware definitions. The removal of nios2-io.h will help modularity and maintenance. Signed-off-by: Thomas Chou

nios2: remove EPCS driver

2014-08-24T03:28:19Z

The Altera EPCS is SPI flash. We have been using SPI flash driver to access EPCS for years. The old EPCS driver could be removed. Signed-off-by: Thomas Chou
