* allow LED initialization without STATUS_LED_BOOTBernhard Nortmann2015-10-24-5/+13
| | | | | | | | | | | | | | | | | | | | For current U-Boot to initialize status LEDs via status_led_init(), it is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined. This may be a particular concern with GPIO LEDs, where __led_init() is required to correctly set up the GPIO (gpio_request and gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't called, which could leave the user with a non-functional "led" command - due to the fact that the LED routines in gpio_led.c use gpio_set_value() just fine, but the GPIO never got set up properly in the first place. I think having CONFIG_STATUS_LED is sufficient to justify a corresponding call to status_led_init(), even with no STATUS_LED_BOOT defined. To do so, common/board_r.c needs call that routine, so it now is exposed via status_led.h.

* add generic stubs for GPIO LEDsBernhard Nortmann2015-10-23-0/+54
| | | | | | | | | | | | | | | | | For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED), it may be useful to have some generic stubs (wrapper functions) for the "colored" LEDs. This allows defining STATUS_LED_* values directly to GPIO numbers, e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */ To keep those optional, it's probably best to introduce an additional configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that. Placing the code in drivers/misc/gpio_led.c also ensures that it automatically depends on CONFIG_GPIO_LED too.

* nios2: convert cache flush to use dm cpu dataThomas Chou2015-10-23-98/+133
| | | | | | | | | | | | | | | Convert cache flush to use dm cpu data. The original cache flush functions are written in assembly and use CONFIG_SYS_{I,D}CACHE_SIZE... macros. It is difficult to convert to use cache configuration in dm cpu data which is extracted from device tree. The cacheflush.c of Linux nios2 arch uses cpuinfo structure, which is very close to our dm cpu data. So we copy and modify it to arch/nios2/lib/cache.c to replace the old cache.S.

* nios2: set default cache configuration in start.SThomas Chou2015-10-23-7/+15
| | | | | | | | | | | | | | | | | | | Set default icache and dcache configuration for start.S. We want to remove the CONFIG_SYS_{I,D}CACHE_SIZE... configuration macros. As we are just barely starting from reset, there is no luxury of device tree. We will set some maximum cache configuration so that it will work for most configurations. This is used only in this start.S. The speed penalty is only once here. After start up, during board initialization, cpu information will be extracted from device tree. Then cache flush operations will have correct cache configurations. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Marek Vasut <marex@denx.de>
