* ARM: rpi: add Raspberry Pi 4 supportAhmad Fatoum2022-06-172-0/+19
| | | | | | | | | | | | | | | With basic driver support added in previous commits, add the boilerplate to have barebox-raspberry-pi.img usable as bootloader for the Raspberry Pi 4 in 64-Bit mode. Tested peripherals: - SD-Card - pinctrl - clocksource - mini-UART Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20220609055922.667016-19-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | usb: dwc3: align dwc3 clocks with bindingMichael Riesch2022-05-113-62/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device tree bindings snps,dwc3.yaml and rockchip,dwc3.yaml specify different clock names. This inconsistency did not matter in the past as the snps,dwc3 used to be a subnode of the rockchip,rk3xyz-dwc3 glue node. For the RK356x, however, a different approach is used and the two nodes are merged. Therefore, the dwc3 driver must accept both groups of clock names. This step is a prerequisite for replacing the initial rk3568.dtsi in arch/arm/dts with the mainline Linux version. For compatibility, the former is updated accordingly. This also illustrates the migration from glue node and subnode to a single device tree node.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was no device tree binding in mainline Linux when this driver was introduced in barebox. This has changed in the mean time, hence we need to align the clocks and resets in this driver. This step is a prerequisite for replacing the initial rk3568.dtsi in arch/arm/dts with the mainline Linux version. For compatibility, the former is updated accordingly.

* | ARM: pbab01: allow USB-OTG port runtime configurationAndrej Picej2022-04-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit a5a4c1d5a3 ("dts: update to v5.13-rc1"), which synced kernel dts, USB-OTG port on phyFLEX board was set to work only in peripheral mode. This has to do with phyFLEX baseboard hardware bug, which prevents correct USB OTG ID pin detection in kernel code. Unlike linux kernel, barebox doesn't support OTG auto-detection mode via ID pin. In barebox, user has to select desired USB mode of operation by setting 'otg.mode' variable. Thus set the 'dr_mode' property to "otg" to be able to later select USB OTG operating mode at runtime (either host or peripheral).

| * | ARM: i.MX8MN: add i.MX8MN-EVK supportAhmad Fatoum2021-10-052-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With driver support in place, we can now build and run barebox in the i.MX8MN. 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.

| * | ARM: i.MX8MM: add reboot to serial download modeAhmad Fatoum2021-08-093-0/+20
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
