* ARM: socfpga: Set reset-names property for &mmcIan Abbott2021-11-221-0/+4
| | | | | | | | | | | | | | | | | | | The device tree node for SoCFPGA's MMC device has the `resets =` property, but is missing the `reset-names = "reset";` property. This causes the "dw_mmc" driver to output a warning: WARNING: dw_mmc ff704000.dwmmc0@ff704000.of: error claiming reset: Invalid argument Add the missing `reset-names` property to the `&mmc` node in "arch/arm/dts/socfpga.dtsi". It probably needs fixing in the upstream Linux device tree sources too!

The barebox bootloader spec loader will ignore the entry because the 'compatible' string in the root node of the DTB does not match what barebox expects. Remove the 'compatible' string list from "arch/arm/dts/socfpga_cyclone5_sockit.dts" so that barebox uses the upstream compatible string list. Also remove the 'model' string ("Terasic SoCkit") which is identical to the upstream 'model' string. Finally, update the `of_machine_is_compatible("terasic,sockit")` function call in `socfpga_console_init()` to use the "terasic,socfpga-cyclone5-sockit" string.

Following tested working: - Setting up DDR4 SDRAM - Booting from SD-Card - Booting from eMMC - Updating barebox in SD-Card/eMMC boot partition - USB Fastboot, ACM gadgets - UART - Early I2C with bd71837 - Ethernet - Loading and communicating with TF-A The resulting image supports both DDR4 and LPDDR4. They use different PMICs, so probing the i2c addresses of them indicates what DRAM type to setup. I have only tested this on a DDR4 EVK, but the LPDDR4 code is equivalent to what's already used in barebox with i.MX8M Mini and Plus, so it should work(tm). Notably missing: - boot from USB SDP doesn't work. early debug_ll doesn't indicate that barebox PBL was actually entered. This can follow later though.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX8MM reference manual follows long established tradition in not documenting BootROM magic reboot codes. For older i.MX variants, the values can be seen in the bmode tables of Freescale's U-Boot patches. There are no such patches for the i.MX8M, but testing shows that mw 0x30390094 0x10 ; mw 0x30390098 0x40000000 is one of the configurations that trigger serial download on next warm reset on an i.MX8MM. Describe this in the device tree, so gpr.reboot_mode.next=serial reset -r imxwd-warm does the right thing for that SoC. This all might work for other i.MX8M variants as well, but the dtsi can be genericized later on when tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the latest NVMEM enhancements merged, barebox networking core now always consults NVMEM cells referenced in the network controller device tree node before it falls back to randomizing a new address. The SAM5D27-SOM1 has a 256 byte EEPROM, which holds a MAC address in its last 6 bytes. Describe this in the device tree, so boards using the SoM will get an unique MAC address assigned and fixed up into the kernel device tree.

Mimic what we do there to get rid of the sama5d3 board code. Unlike the microchip-ksz9477-evb, the barebox support for this board includes NAND, which is not yet up to date with respect to DT: - SMC for NAND configuration has no DT driver. Instead the board driver create this device - We don't support the newer NAND DT bindings (EBI). The device trees fix this up, so barebox sees the old bindings with the upstream partition layout. In future, this could be fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | with kernel" This reverts commit 72ba815bf6feaa0a98d2496f52784dd5b4258e73. The NVMEM name-clashing has been fixed on Linux-upstream. NVMEM devices are now registered with the unique device names instead of the MTD-partition names. This fix is no longer needed.

* | ARM: i.MX: Add support for Skov i.MX6 boardsJuergen Borleis2021-04-134-0/+599
|/ | | | | | | | | | | | | | | | | | The Skov platform potentially consists of many variants of CPUs (i.MX6S/DL and i.MX6D/Q), NAND memories (size differs from 256 MiB to 8 GiB) and populated SDRAM (256 MiB up to 2 GiB). All these variants share one PCB. Some bootstrap resistors are provided which decode the variant and which allow for it's detection at runtime. This information is needed to choose the bootspec entry with the matching devicetree to boot the system. Based upon this mechanism usage of a single Barebox image and Linux root filesystem for all known board variants is made possible.
