* zynq: Move SPL console init out of board_init_f()Simon Glass2015-10-24-1/+1
| | | | | | | | | | | | | | We should not init the console this early since it precludes using driver model for the UART, since it is not set up at the start of board_init_f(). See the README for more information. The debug UART does not have this restriction. If we want to do early init with the console on it can be done in spl_board_init(). Move the preloader_console_init() call from board_init_f() to board_init_r().

* fs-test.sh: fix pre-requisite detectionStephen Warren2015-10-24-1/+1
| | | | | | | | | | | | | | | | | In the following snippet: if [ ! -x `which $prereq` ]; then When $prereq does not exist, `which $prereq` evaluates to the empty string, which results in *no* argument being passed to the -x operator, which then evaluates to true, which is the equivalent of the prereq having been found. In order for this to fail as expected, we must pass an empty argument, which then causes -x to fail. Do this by wrapping the `` in quotes so there's always an argument to -x, even if the value of the argument is zero-length.

* test: fat: add test of non-contiguous file readsStephen Warren2015-10-24-0/+113
| | | | | | | | | | | | | | | | | In my patch series to replace fs/fat with "ff.c", I enhanced ff.c to optimize file reading, so that reads of contiguous clusters are submitted to the IO device as a single read. This test attempts to torture-test edge-cases of that enhancement. BTW, the only way I found to validate that this script actually does create non-contiguous files was to manually inspect the FAT bitmap in a hex dump of the FAT image. hdparm --fibmap doesn't work on loop-mounted filesystems. filefrag -v -e seems to lie about files being contiguous when they aren't.

* 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.

| | | | | | | | | | | | | | | 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.

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.
