2015-10-24Fix bad return value checks (detected with Coccinelle)Thomas Huth
In the "Getting Started with Coccinelle - KVM edition" presentation that has been held by Julia Lawall at the KVM forum 2015 (see the slides at http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf), she pointed out some bad return value checks in U-Boot that can be detected with Coccinelle by using the following config file: @@ identifier x,y; identifier f; statement S; @@ x = f(...); ( if (x < 0) S | if ( - y + x < 0) S ) This patch now fixes these issues.

2015-10-24allow LED initialization without STATUS_LED_BOOTBernhard Nortmann
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.

2015-10-23add generic stubs for GPIO LEDsBernhard Nortmann
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.

With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be parsed in xlate gpio drivers-ops.

2015-10-22remoteproc: Introduce a sandbox dummy driverNishanth Menon
Introduce a dummy driver for sandbox that allows us to verify basic functionality. This is not meant to do anything functional - but is more or less meant as a framework plumbing debug helper.

2015-10-22drivers: Introduce a simplified remoteproc frameworkNishanth Menon
Many System on Chip(SoC) solutions are complex with multiple processors on the same die dedicated to either general purpose of specialized functions. Many examples do exist in today's SoCs from various vendors. Typical examples are micro controllers such as an ARM M3/M0 doing a offload of specific function such as event integration or power management or controlling camera etc. Traditionally, the responsibility of loading up such a processor with a firmware and communication has been with a High Level Operating System(HLOS) such as Linux. However, there exists classes of products where Linux would need to expect services from such a processor or the delay of Linux and operating system being able to load up such a firmware is unacceptable. To address these needs, we need some minimal capability to load such a system and ensure it is started prior to an Operating System(Linux or any other) is started up. NOTE: This is NOT meant to be a solve-all solution, instead, it tries to address certain class of SoCs and products that need such a solution. A very simple model is introduced here as part of the initial support that supports microcontrollers with internal memory (no MMU, no execution from external memory, or specific image format needs). This basic framework can then (hopefully) be extensible to other complex SoC processor support as need be.
