| | | | | | | | | | | | | | | The files 'mxs.rst' and 'imx.rst' used the same chapter headline: Freescale i.MXs This confuses sphinx. It does not support having the same headline at the same level twice and hides the other chapter. Just rename the chapter heading to avoid that.

* | ARM: i.MX50: Add support for i.MX50 based Amazon Kindle e-book readersAlexander Kurz2017-04-241-0/+58
|/ | | | | | | | | | | | | | | | | | | | | | | | The Kindle Model No. D01100 (Kindle Wi-Fi), D01200 (Kindle Touch) and EY21 (Kindle Paperwhite) are refered as the Kindle 4th and 5th generation. Those models are based on an i.MX50 SoC and use LPDDR1 or LPDDR2 Memory. The devices boot in internal boot mode from a build-in eMMC, alternatively some devices may be set into USB-downloader mode by pressing a specific key at startup. Add support for the i.MX50 based Kindle device and make barebox a drop-in replacement for the factory shipped u-boot image. Notable features: - Support for eMMC, USB, UART, I2C, SPI and Keys (except keyboard). - LPDDR1 and LPDDR2 setup is done via DCD, the same imximage may be used for USB-startup and for installation. - Support for vendor specific ATAGs that are required for the Kindle-System. - usbserial barebox console access by pressing Select button at startup, alternatively full console support on connector J14.

* state: Make pointing to the backend using a phandle the only supported methodSascha Hauer2017-03-311-7/+20
| | | | | | | | | | All other methods are broken for some time already: When starting the kernel the state code rewrites the state node in the device tree and replaced the "backend" property with a phandle - even when the target can't be described as a phandle. Since using phandles is the nicest way to point to the storage device anyway remove the other methods. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | | boot: add framework for redundant boot scenariosMarc Kleine-Budde2016-09-223-0/+277
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several use cases where a redundant Linux system is needed. The barebox bootchooser framework provides the building blocks to model different use cases without the need to start from the scratch over and over again. The bootchooser works on abstract boot targets, each with a set of properties and implements an algorithm which selects the highest priority target to boot. See the documentation contained in this patch for more information.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

* 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.
