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.

sandbox: terminate os_dirent_ls() result list

2014-06-23T21:37:24Z

Each node in the linked-list that os_dirent_ls() returns has its next pointer set only when the next node is created. For the last node in the list, there is no next node, so this never happens, and the next pointer is never initialized. Explicitly initialize the next pointer so that it isn't dangling. Without this, "sb ls" might crash. Signed-off-by: Stephen Warren Acked-by: Simon Glass

Makefile: Support include files for .dts files

2014-06-20T17:55:03Z

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 Acked-by: Stephen Warren Reviewed-by: Masahiro Yamada

sandbox: Support iotrace feature

2014-06-20T17:54:42Z

Support the iotrace feature for sandbox, and enable it, using some dummy I/O access methods. Signed-off-by: Simon Glass

dm: rename device struct to udevice

2014-05-27T14:21:32Z

using UBI and DM together leads in compiler error, as both define a "struct device", so rename "struct device" in include/dm/device.h to "struct udevice", as we use linux code (MTD/UBI/UBIFS some USB code,...) and cannot change the linux "struct device" Signed-off-by: Heiko Schocher Cc: Simon Glass Cc: Marek Vasut

Revert "sandbox: move source files from board/ to arch/sandbox/"

common/board_f: Initialized global data for generic board

2014-05-12T19:20:05Z

Some platforms (tested on mpc85xx, mpc86xx) use global data before calling function baord_inti_f(). The data should not be cleared later. Any arch which uses global data in generic board board_init_f() should define CONFIG_SYS_GENERIC_GLOBAL_DATA.

sandbox: move source files from board/ to arch/sandbox/

2014-05-09T20:51:14Z

Prior to commit 33a02da0, all boards must have board/${BOARD}/ or board/${VENDOR}/${BOARD}/ directory. Now this rule is obsolete. It looks weird that sandbox defines "vendor" and "board" just for meeting the old U-Boot directory structure. Signed-off-by: Masahiro Yamada Cc: Simon Glass
