Per a request from Andre Przywara and agreed with by Peter Hoyes, the vexpress aemv8r support wasn't quite ready to be merged, but the discussion had moved off list. We should keep the first patch in the series for now, but revert the rest.

2021-09-02vexpress64: Add BASER_FVP vexpress board variantPeter Hoyes1-1/+1
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.

2021-09-01board: stemmy: Update documentationStephan Gerhold3-0/+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.

2021-08-31qfw: Switch to CONFIG_SYS_LOAD_ADDR from CONFIG_LOADADDRTom Rini1-1/+1
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. Switch the code to use CONFIG_SYS_LOAD_ADDR and update the documentation. Cc: Bin Meng <bmeng.cn@gmail.com> Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2021-08-31watchdog: add gpio watchdog driverRasmus Villemoes1-0/+19
A rather common kind of external watchdog circuit is one that is kept alive by toggling a gpio. 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.
