| * ARM: stm32mp: add board support for STM32MP135F-DKAhmad Fatoum2022-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have the needed drivers in place to support the upcoming STM32MP131. Linux already has a basic DT for the DK board. Add a barebox board that leverages it. To try it out modify the existing FIP with: fiptool update --nt-fw build/images/barebox-stm32mp-generic-bl33.img \ --hw-config build/arch/arm/dts/stm32mp135f-dk.dtb \ mmcblk0p3 Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20220221103625.3728055-2-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: stm32mp: build extra barebox-stm32mp-generic-bl33.imgAhmad Fatoum2022-02-231-7/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ARM: stm32mp: change stm32image extension to .stm32Ahmad Fatoum2022-02-231-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The .img extension for stm32mp1 images is unfortunate. 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. To make existence of the STM32 header evident, rename the extension from .img to .stm32. As it's still supported by TF-A, have symlinks, so user build script can use the old names for now.

We already have some target tools, but support for those is easier, because they don't link against libraries. We use pkg-config to get cc and ld flags, but we always assume that pkg-config is for the host system and there is no well-defined way to request pkg-config for the target system. Support this by introducing a new CROSS_PKG_CONFIG. This will be consulted only for target tools and default to $(CROSS_COMPILE)pkgconfig. Users can override it as necessary, for example, with Yocto, pkg-config will be for the cross environment, so target tools can now be built with: export ARCH=sandbox CROSS_COMPILE=aarch64-linux-gnu- export CROSS_PKG_CONFIG=pkg-config scripts make targettools_defconfig make scripts Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20210917174127.23345-4-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

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).

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.

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.

This necessitates using __naked, which probably has been our most frequent cause of misscompiled C code. GCC is quite clear that: Only basic asm statements can safely be included in naked functions While using extended asm or a mixture of basic asm and C code may appear to work, they cannot be depended upon to work reliably and are not supported. But some boards use it anyway, because it's nice to avoid writing assembly. Reading generated assembly to spot compiler miscompilation isn't that nice though, so add some documentation, comments and compiler diagnostics to hopefully reduce future porting effort.

|/ | | | | | | | | | | | This directory is an optional part of the defaultenv-2 and is documented there. There should be a sentence about it in the reboot-mode docs as well, because users can add it to their environments as well to avoid doing if-else chains in the init scripts.
