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

sandbox: dts: Add a serial console node

2014-09-10T19:00:00Z

If the sandbox device tree is provided to U-Boot (with the -d flag) then it will use the device tree version in preference to the built-in device. The only difference is the colour. Signed-off-by: Simon Glass

kconfig: add board Kconfig and defconfig files

2014-07-30T12:48:01Z

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/.

sandbox: Remove all drivers before exit

2014-07-23T13:07:24Z

Drivers are supposed to be able to close down cleanly. To set a good example, make sandbox shut down its driver model drivers and remove them before exit. It may be desirable to do the same more generally once driver model is more widely-used. This could be done during bootm, before U-Boot jumps to the OS. It seems far too early to make this change.

sandbox: Support pre-relocation malloc()

2014-07-23T13:06:13Z

Set up and zero global data before board_init_f() is called so that we can remove the need for CONFIG_SYS_GENERIC_GLOBAL_DATA. Signed-off-by: Simon Glass

sandbox: Set up global data before board_init_f()

2014-07-23T13:05:39Z

At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.

build: define CPU only when arch/${ARCH}/cpu/${CPU} exists

2014-07-07T23:42:34Z

The directory arch/${ARCH}/cpu/${CPU} does not exist in avr32, blackfin, microblaze, nios2, openrisc, sandbox, x86. These architectures have only one CPU type. Defining CPU should not be required for such architectures. This commit allows cpu field (= the 3rd field of boards.cfg) to be kept blank.

sandbox: change local_irq_save() to macro

2014-06-23T21:37:24Z

local_irq_save() should be a macro, not a function because local_irq_save() saves flag to the given argument. GCC is silent about this issue, but Clang warns: In file included from lib/asm-offsets.c:15: In file included from include/common.h:20: In file included from include/linux/bitops.h:110: arch/sandbox/include/asm/bitops.h:59:17: warning: variable 'flags' is uninitialized when used here [-Wuninitialized] local_irq_save(flags); ^~~~~ That change causes another warning: In file included from include/linux/bitops.h:110:0, from include/common.h:20, from lib/asm-offsets.c:15: arch/sandbox/include/asm/bitops.h: In function ‘test_and_set_bit’: arch/sandbox/include/asm/bitops.h:56:16: warning: unused variable ‘flags’ [-Wunused-variable] So, flags should be set to __always_unused.
