* spl: Add debugging info for spl_mmc bootSimon Glass2015-07-21-2/+7
| | | | | | Add a few messages to indicate progress and failure. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: led: Add a driver for GPIO-controlled LEDsSimon Glass2015-07-21-0/+163
| | | | | | | Add a simple driver which allows use of LEDs attached to GPIOs. The linux device tree binding is used. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add support for LEDsSimon Glass2015-07-21-0/+152
| | | | | | | | | Add a simple uclass for LEDs, so that these can be controlled by the device tree and activated when needed. LEDs are referred to by their label. This implementation requires a driver for each type of LED (e.g GPIO, I2C). Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add support for generic system controllers (syscon)Simon Glass2015-07-21-0/+131
| | | | | | | | | | | Many SoCs have a number of system controllers which are dealt with as a group by a single driver. It is a pain to have to add lots of compatible strings and/or separate drivers for each. Instead we can identify the controllers by a number and request the address of the one we want. Add a simple implementation of this which can be used by SoC driver code. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add support for register maps (regmap)Simon Glass2015-07-21-0/+159
| | | | | | | | | | | Add a simple implementaton of register maps, supporting only direct I/O for now. This can be enhanced later to support buses which have registers, such as I2C, SPI and PCI. It allows drivers which can operate with multiple buses to avoid dealing with the particulars of register access on that bus. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: gpio: Add dm_gpio_request() to manually request a GPIOSimon Glass2015-07-21-1/+13
| | | | | | | This function can be used for testing to manually request a GPIO for use, without resorting to the legacy GPIO API. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: core: Correct device_get_child_by_of_offset() parameterSimon Glass2015-07-21-3/+3
| | | | | | This parameter is named 'seq' but should be named 'of_offset'. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Add a function to find any device from device treeSimon Glass2015-07-21-0/+39
| | | | | | | | | | | | In some rare cases it is useful to be able to locate a device given a device tree node offset. An example is when you have an alias that points to a node and you want to find the associated device. The device may be SPI, MMC or something else, but you don't need to know the uclass to find it. Add a function to do a global search for a device, given its device tree offset. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Use debug() instead of printf() for failuresSimon Glass2015-07-21-3/+3
| | | | | | | | To avoid bloating SPL code, use debug() where possible in the driver model core code. The error code is already returned, and can be investigated as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Move the tree/uclass dump code into its own fileSimon Glass2015-07-21-79/+106
| | | | | | | | | | In SPL it is sometimes useful to be able to obtain a dump of the current driver model state. Since commands are not available, provide a way to directly call the functions to output this information. Adjust the existing commands to use these functions. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Drop special-case sandbox console codeSimon Glass2015-07-21-5/+1
| | | | | | | | | At present printf() skips output if it can see there is no console. This is really just an optimisation, and is not necessary. Also it is currently incorrect in some cases. Rather than update the logic, just remove it so that we don't need to keep it in sync. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Allow debug UART to support an early consoleSimon Glass2015-07-21-0/+19
| | | | | | | When there is no console ready, allow the debug UART to be used for output. This makes debugging of early code considerably easier. Signed-off-by: Simon Glass <sjg@chromium.org>
* debug_uart: Remove use of asmlinkageSimon Glass2015-07-21-12/+10
| | | | | | | This does not actually help any current arch. For x86 it makes it harder to call (requires stack) and for ARM it has no effect. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a way of checking the position of a structure memberSimon Glass2015-07-21-0/+11
| | | | | | | | | | | | U-Boot uses structures for hardware access so it is important that these structures are correct. Add a way of asserting that a structure member is at a particular offset. This can be created using the datasheet for the hardware. This implementation uses Static_assert() since BUILD_BUG_ON() only works within functions. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: arm: Put driver model I2C drivers before legacy onesSimon Glass2015-07-21-5/+5
| | | | | | | | | | Driver-model I2C drivers can be picked up by the linker script rule for legacy drivers. Change the order to avoid this. We could make the legacy code depend on !CONFIG_DM_I2C but that is not necessary and it is good to keep conditions to a minimum. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Reduce SPL device tree sizeSimon Glass2015-07-21-2/+42
| | | | | | | | | The SPL device tree size must be minimised to save memory. Only include properties that are needed by SPL - this is determined by the presence of the "u-boot,dm-pre-reloc" property. Also remove a predefined list of unused properties from the nodes that remain. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add fdtgrep toolSimon Glass2015-07-21-1/+1239
| | | | | | | | | | | | | | | | | | | | | | | | This tool allows us to extract subsets of a device tree file. It is used by the SPL vuild, which needs to cut down the device tree size for use in limited memory. This tool was originally written for libfdt but it has not been accepted upstream, so for now, include it in U-Boot. Several utilfdt library functions been included inline here. If fdtgrep is eventually accepted in libfdt then we can bring that version of libfdt in here, and drop fdtgrep (requiring that fdtgrep is provided by the user). If it is not accepted then another approach would be to write a special tool for chopping down device tree files for SPL. While it would use the same libfdt support, it would be less code than fdtgrep.c because it would not have general-purpose functions. Another approach (which was used with v1 of this series) is to sprinkler all the device tree files with #ifdef. I don't like that idea. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add fdt_first/next_region() functionsSimon Glass2015-07-21-2/+731
| | | | | | | | These have been sent upstream but not accepted to libfdt. For now, bring these into U-Boot to enable fdtgrep to operate. We will use fdtgrep to cut device tree files down for SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add a function to remove unused strings from a device treeSimon Glass2015-07-21-0/+49
| | | | | | | | | | | | Property names are stored in a string table. When a node property is removed, the string table is not updated since other nodes may have a property with the same name. Thus it is possible for the string table to build up a number of unused strings. Add a function to remove these. This works by building a new device tree from the old one, adding strings one by one as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
* mkimage: Display a better list of available image typesSimon Glass2015-07-21-33/+95
| | | | | | | | | | | Offer to display the available image types in help. Also, rather than hacking the genimg_get_type_id() function to display a list of types, do this in the tool. Also, sort the list. The list of image types is quite long, and hard to discover. Print it out when we show help information. Signed-off-by: Simon Glass <sjg@chromium.org>
