* dm: test: Add a test for the system controller uclassSimon Glass2015-07-21-0/+1

* sandbox: Add a warm and cold reset driverSimon Glass2015-07-21-0/+1
| | | | | | | | Add drivers for sandbox. One can only perform a warm reset (which does nothing). The other can perform a cold reset or a power reset (the latter will quit U-Boot). These can be used for testing the reset uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add a system reset uclassSimon Glass2015-07-21-0/+1
| | | | | | | | | | | | | | | | It is common for system reset to be available at multiple levels in modern hardware. For example, an SoC may provide a reset option, and a board may provide its own reset for reasons of security or thoroughness. It is useful to be able to model this hardware without hard-coding the behaviour in the SoC or board. Also there is a distinction sometimes between resetting just the CPU (leaving GPIO state alone) and resetting all the PMICs, just cutting power. To achieve this, add a simple system reset uclass. It allows multiple devices to provide reset functionality and provides a way to walk through them, requesting a particular reset type until is it provided.

* armv8/fsl-lsch3: Add Freescale Debug Server driverBhupesh Sharma2015-04-21-0/+1
| | | | | | | | | | | | | The Debug Server driver is responsible for loading the Debug server FW on the Service Processor (Cortex-A5 core) on LS2085A like SoCs and then polling for the successful initialization of the same. TOP MEM HIDE is adjusted to ensure the space required by Debug Server FW is accounted for. MC uses the DDR area which is calculated as: MC DDR region start = Top of DDR - area reserved by Debug Server FW Signed-off-by: Bhupesh Sharma <bhupesh.sharma@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

|/ | | | | | | | | | | | Add yet another OCOTP driver for this i.MX family. This time, it's a driver for the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too different from the i.MX6 one that I could not use the mxc_ocotp.c driver without making it into a big pile of #ifdef . This driver implements the regular fuse command interface, but due to the IP blocks' limitation, we support only READ and PROG functions.

* x86: Add CBMEM console driver for corebootVadim Bendebury2012-11-30-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode flags: 64bit ilck stag led pmp pio ... Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose. Ether the buffer size will have to be increased, or the coreboot verbosity permanently reduced. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

The power part of the the function is moved to twl4030_power_init in drivers/power/twl4030.c The power compilation is conditional on the existing config variable CONFIG_TWL4030_POWER. The led part is moved to twl4030_led_init in the new file drivers/misc/twl4030_led.c The led compilation is conditional on the new config variable CONFIG_TWL4030_LED The directory board/omap3/common was removed because power_init_r was the only function in it.
