* sandbox: Convert GPIOs to use driver modelSimon Glass2014-03-04-88/+151
| | | | | | Convert sandbox over to use driver model GPIOs. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add GPIO support and testsSimon Glass2014-03-04-0/+483
| | | | | | | | | | | | | | | | | | | | | | | | | | Add driver model support for GPIOs. Since existing GPIO drivers do not use driver model, this feature must be enabled by CONFIG_DM_GPIO. After all GPO drivers are converted over we can perhaps remove this config. Tests are provided for the sandbox implementation, and are a sufficient sanity check for basic operation. The GPIO uclass understands the concept of named banks of GPIOs, with each GPIO device providing a single bank. Within each bank the GPIOs are numbered using an offset from 0 to n-1. For example a bank named 'b' with 20 offsets will provide GPIOs named b0 to b19. Anonymous GPIO banks are also supported, and are just numbered without any prefix. Each time a GPIO driver is added to the uclass, the GPIOs are renumbered accordinging, so there is always a global GPIO numbering order.

* dm: Add a demonstration/example driverSimon Glass2014-03-04-0/+432
| | | | | | | | | | | | | | | | As an example of how to write a uclass and a driver, provide a demo version of each, accessible through the 'demo' command. To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO. The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and CONFIG_DM_DEMO_SHAPE.

* dm: Add basic testsSimon Glass2014-03-04-0/+1426
| | | | | | | | | | | | | | | | | | | | Add some tests of driver model functionality. Coverage includes: - basic init - binding of drivers to devices using platform_data - automatic probing of devices when referenced - availability of platform data to devices - lifecycle from bind to probe to remove to unbind - renumbering within a uclass when devices are probed/removed - calling driver-defined operations - deactivation of drivers when removed - memory leak across creation and destruction of drivers/uclasses - uclass init/destroy methods - automatic probe/remove of children/parents when needed This function is enabled for sandbox, using CONFIG_DM_TEST.

* Add cmd_process_error() to report and process errorsSimon Glass2014-03-04-0/+19
| | | | | | | | | | | | U-Boot now uses errors defined in include/errno.h which are negative integers. Commands which fail need to report the error and return 1 to indicate failure. Add this functionality in cmd_process_error(). For now this merely reports the error number. It would be possible also to produce a helpful error message by storing the error strings in U-Boot.

| * arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini2014-02-26-138/+248
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

It unfortunately has had a impact on size on SPL as well. For example on SDP4430, 32032 bytes before/MLO 35416 bytes after/MLO With this mentioned commit, MLO stops booting on SDP4430 as only 32K is accessible for non-secure (bootloader) s/w on GP devices and the size increase to 56K fails boot. On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf, MLO is now at size 35592 bytes, However, I2C is not necessary for SPL to function as we use SR_I2C for controlling the PMIC. Disabling I2C reduces MLO to 32224 bytes which allows OMAP4 GP platform to boot up. Since this is common for all OMAP4 platforms, remove the need for I2C for SPL builds in the common config.
