* ARM i.MX: add SoC type detection for i.MX6SLAlexander Kurz2017-02-011-0/+4
| | | | | | | | | | | | | | | | | | | | The i.MX6 series SoC type is determined by barebox by examining the USB_ANALOG_DIGPROG aka IMX6_ANATOP_SI_REV register. This register is located at a common offset for all mx6 SoC - except for i.MX6SL where a different offset is used. This creates a dilemma while distinguishing the mx6sl from non-mx6sl SOC since the SoC type identification register location is type specific itself. Access to undocumented and probably invalid or unpredictable registers should be avoided as possible. For the mx6sl detection an access to the general USB_ANALOG_DIGPROG @0x260 cannot be avoided when running on mx6sl. This register contained the value 0x00014009 for different mx6sl Rev. 1.2 based e-book readers using MCIMX6L7DVN10AB and MCIMX6L8DVN10AB SoC. This implementation assumes the value of MAJOR_UPPER (here 0x01) to be smaller than the smallest non-6sl MAJOR_UPPER (0x61 for mx6s).

* ARM i.MX35: Add support for the Amazon Kindle3Alexander Kurz2016-07-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | The main idea behind this patch is to avoid redundant code. Because of the module similarities of all i.MX6 based phytec boards, we can merge its code. The phytec-som-imx6 merges the code of all i.MX6 based phytec SOMs. So we will have only one "board" in the barebox for phyCARD-i.MX6 and phyFLEX-i.MX6.

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 commit add a very basic code to allow Barebox to be booted from IRAM. Given that the amount of IRAM on most i.MX variants is insufficient to contain a copy of Barebox with any reasonable degree of functionality this code uses IRAM only as a temporary location and eventually bootstraps from DRAM. But the presense of the intermediate IRAM-only stage allows to add provisions to test the area of DRAM that Barebox would be using to facilitate various testing scenarious.
