* | Documentation: i.MX8M: add EVK barebox installation documentationAhmad Fatoum2023-02-213-0/+66
|/ | | | | | | | | | | | | The barebox i.MX images have a preamble that pads the i.MX header to the offset expected by the BootROM. This allows writing barebox images directly to offset 0 on SD-Cards and eMMC user area. For some i.MX8M, these images can't be directly written to eMMC boot partitions and instead require special handling. Add a note about this to the documentation.

* restart: add reset -w for warm bootrom resetAhmad Fatoum2022-10-271-1/+1
| | | | | | | | | | | | | | | | | | We currently support reboot mode communication with BootROMs of the i.MX6Q/DL, i.MX8MM and STM32MP15x. For each of these, the user must take care to use the correct reset as the highest priority reset often clears the non-volatile register mapped by the syscon holding the reboot mode. As we only have one BootROM, we can improve usability by adding a global flag that describes whether a restart handler is suitable for use after a bootrom reboot mode write. Add a flag bit describing this and allow populating it from the device tree as well as from drivers. Existing i.MX/STM32 drivers will be moved onto this in follow-up commits.

* ARM: i.MX8MP: adapt atf bl31 base addressMarco Felsch2022-07-111-4/+7
| | | | | | | | | | | | | | | | | | | | | | With i.MX8MP A1 silicon the OCRAM space is extended to 576KB whereas the pre-release silicon has only 512KB. So the upstream TF-A adapted the base address to move BL31 to the last 128KB of the OCRAM. The adaption was a bit messy because each version changed it: - v2.4 base addr = 0x960000 (original) - v2.5 base addr = 0x970000 (adapted to new silicon revision) - v2.6 base addr = 0x960000 (changed back by accident) - v2.7 base addr = 0x970000 (accident fixed) With v2.7 it is correctly set for A1 silicon onwards and we strongly recommend to use this version or newer. This commit also adapts the documentation for the i.MX8MP-EVK to reference the upstream TF-A and to point out our favorite version.

This work by including DTs for all enabled boards in config and then consulting the mailbox interface at runtime to deduce which DT to pass to barebox proper. An alternative would have been to use the existing barebox-dt-2nd.img with a VideoCore-supplied device tree, but that has the drawback of requiring barebox to observe the same bindings as the kernel that's booted later. This approach makes migration straight-forward, because no difference in VideoCore configuration is required.

| | | | | | | | | | | | | barebox-dt-2nd.img expects being loaded at an offset, so the stack can grow down from entry point. The STM32MP TF-A default is to not have an offset. Avoid this issue by having a stm32mp specific entry point that sets up a 64 byte stack after end of barebox. As it's stm32mp-specific anyway, we can skip the early FDT parsing and ask the SDRAM controller about RAM size.

The format is deprecated and its header makes it not directly executable and thus not suitable as-is for use in a FIP image where the BL33 is run from offset 0.

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).

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.
