* scripts: Add rk-usb-loader toolSascha Hauer2021-11-101-0/+15
| | | | | | | | | This adds a tool suitable for bootstrapping barebox on Rockchip RK3568 SoCs. It has been tested on this SoC only. It might or might not work with minor adjustments on other SoCs.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | The commit a9b2e6089d82686564220013f14e9f0ffcc725e2 allowed generating everything needed in one step. This was however a bit too ambitious. The script now requires that the Altera Embedded SDK is always installed. There are situations where this is unwanted. Beef up the code a little bit to allow having the SDK as an optional argument and make the other input parameters location independent.

| * | ARM: i.MX8MN: add i.MX8MN-EVK supportAhmad Fatoum2021-10-051-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Fatoum2021-08-091-0/+29
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have one other DT-enabled SAMA5D3 board already: microchip-ksz8477-evb, which is basically a sama5d3 xplained in different form factor and with a switch. 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current qemu-virt64 barebox support doesn't look much like what's offered on physical boards. It's not relocatable, lacks PBL and doesn't use device tree. As qemu-system-aarch64 -M virt -kernel already supplies an external device tree, we could just replace all existing support with BOARD_ARM_GENERIC_DT, which builds a barebox image that reuses an externally passed device tree. The 32-bit ARM VIRT support has some board code for host name setting and overlay applying to handle environment and state on flash. We could do without that, given the new virtio-blk support, but the code is already there, so reuse it and drop all current virt64-specific board code. As the barebox ELF image resulting from the build can no longer be directly booted as before and only with -kernel, not -bios, rename the Kconfig symbol, so existing users can notice this during build.
