| * | Introduce non volatile device variablesSascha Hauer2016-07-061-0/+18
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Non volatile device variables are used to make device parameters persistent. They are like normal non volatile variables, but set the values of the device parameters with the corresponding name. Every nv variable beginning with nv.dev is a non volatile device variable. They have the form nv.dev.<devname>.<paramname> and act on the parameter <paramname> of the device named <devname>. The non volatile device variables are designated for example for video modes, ethernet device ip addresses or mtd partitioning. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | ARM i.MX35: Add support for the Amazon Kindle3Alexander Kurz2016-07-111-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Amazon Model No. D00901 Kindle3 is an E-Book reader based on the i.MX35 SOC. The device boots in internal boot mode from a build-in eMMC, alternatively the device may be set into USB-downloader mode when the Vol+ key is pressed on startup. Add support for this device and make barebox a drop-in replacement for the factory shipped u-boot image. Constraints for the use as drop-in replacement: - imximg header (offset 0x400) has a maximum size of 2kB minus 16 byte since the last 16 bytes are used to store a vendor specific hardware desctription identifier - the bootloader space (application plus env) is limited to 256kB minus 16 bytes when installed with offset of 4kB (the u-boot offset was 3kB). A vendor specific device identifier is stored in the gap between application and kernel. The vendor specific identifiers should not be overwritten. Notable features: - Support for eMMC, USB, UART, I2C, SPI and Keys (except keyboard) - Full support for vendor specific ATAGs - usbserial barebox console access by pressing Select button at startup, alternatively full console support on connector J14.

| * | Documentation: imx: external boot capable SOC list completeAlexander Kurz2016-06-271-2/+1
| |/ | | | | | | | | | | | | | | | | | | | | The iMX35 SOC supports both internal and external boot mode, and both modes are supported by barebox. The iMX35 is the latest SOC with support for this mode, none of the later iMX series iMX50, 51, 53, 6SL, 6SDL, 6DQ, 7S or 7D does support it. Let's complete the list.

* rtc: ds1307: Add support for configuring external clock pinTrent Piepho2016-05-301-0/+33
| | | | | | | | | | | | | | | | | | | | The DS1307 has a square wave output pin, which can be used to output a clock signal from the DS1307. Additionally, the DS1308 supports configuring this pin as an input from an external clock source to which it should sync itself. Add support with OF device tree properties to configure these settings. Supported features are using the clock pin as an output, an input, the rate of the pin, and if it should be enabled on battery backup power. The driver does not check that the selected features are supported by the clock chip being used. It is the designer's responsibility to create a valid device tree node; the bootloader does not attempt to be a device tree validator.

* bootm: Optionally add a root= option to Kernel command lineSascha Hauer2016-05-041-0/+14
| | | | | | | | | It becomes a common case that the Kernel is loaded from the filesystem which later becomes the rootfs. This adds a possibility to let bootm automatically append the root= option to the kernel command line. This is done when global.bootm.appendroot is true.

* bbu: Allow to refresh/repair imagesSascha Hauer2016-04-081-0/+8
| | | | | | | | | | Some SoCs allow to store multiple boot images on a device in order to improve robustness. This adds a -r option to barebox_update to indicate we do not want to make an update but instead repair/refresh an existing image. Handlers which want to support this feature must set the BBU_HANDLER_CAN_REFRESH flag during registration. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current barebox,environment node only allows specifying a raw device or partition to load an environment from. Some boards, like OMAP and SoCFPGA, instead want to use a file located in a FAT filesystem. Extend the device tree bindings with a new property 'file-path' that will trigger this behavior. This allows any board using this driver to get the env from a file or from a raw device, instead of each machine type being either raw device only or file only.

Previously we used the same image on both the Vincell and the Vincell-LT image since the differences are not that significant for barebox. Still this was good for quite some confusion internally, so let's properly introduce a second image.

| | | | | | | | | | | | | | | | | | | | | | This patch makes it possible to automatically add a suitable root= option for booting Linux from the same filesystem on which the bootspec entry has been found. This adds an additional 'linux-appendroot' option to bootspec which if set to 'true' will cause barebox to automatically add a root= option.
