* version: Remove global macro U_BOOT_VERSION_STRING from version.hPali Rohár2021-09-171-9/+12

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BASER_FVP board variant is implemented on top of the BASE_FVP board config (which, in turn, is based on the Juno Versatile Express board config). They all share a similar memory map - for BASER_FVP the map is inverted from the BASE_FVP (https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map) * Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same board config as BASE_FVP and JUNO * Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename to vexpress_aemv8.h) * Enable config to switch to EL1 for the BASER_FVP * Create vexpress_aemv8r defconfig * Provide an MPU memory map for the BASER_FVP For now, only single core boot is supported.

* | board: stemmy: Update documentationStephan Gerhold2021-09-013-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Over the time, the "stemmy" U-Boot board was tested on several other Samsung smartphones based on ST-Ericsson NovaThor Ux500. Convert the documentation to reStructuredText at doc/board/ste/stemmy.rst and make the device list complete. Also note that the board now boots into USB Fastboot instead of just ending up at the U-Boot prompt. The device table is mostly taken from the postmarketOS wiki article (https://wiki.postmarketos.org/wiki/ST-Ericsson_NovaThor_U8500). All the newly added devices were tested by Linus Walleij.

Add a driver for handling such a watchdog. The corresponding linux driver apparently has support for some watchdog circuits which can be disabled by tri-stating the gpio, but I have never actually encountered such a chip in the wild; the whole point of adding an external watchdog is usually that it is not in any way under software control. For forward-compatibility, and to make DT describe the hardware, the current driver only supports devices that have the always-running property. I went a little back and forth on whether I should fail ->probe or only ->start, and ended up deciding ->start was the right place. The compatible string is probably a little odd as it has nothing to do with linux per se - however, I chose that to make .dts snippets reusable between device trees used with U-Boot and linux, and this is the (only) compatible string that linux' corresponding driver and DT binding accepts. I have asked whether one should/could add "wdt-gpio" to that binding, but the answer was no: https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/ If someone feels strongly about this, I can certainly remove the "linux," part from the string - it probably wouldn't the only place where one can't reuse a DT snippet as-is between linux and U-Boot.

|/ | | | | | | | | | | | | All platforms define CONFIG_SYS_LOAD_ADDR, but only some define CONFIG_LOADADDR. Very very rarely are these not the same address, and qemu-ppce500 is one such case. However, based on reading the history of the code, this mismatched value was simply a copy-paste from other PowerPC platforms where it is this unused currently.
