* ARM64: add optional EFI stubAhmad Fatoum2024-03-051-0/+1
| | | | | | | | | | | While very recent binutils releases have dedicated efi-*-aarch targets, we may want to support older toolchains. For this reason, we import the kernel's EFI stub PE fakery, so the same barebox-dt-2nd.img may be loaded as if it were a "normal" or an EFI-stubbed kernel.

| * clk: select CLKDEV_LOOKUP from COMMON_CLKAhmad Fatoum2024-01-191-14/+0
| | | | | | | | | | | | | | | | | | | | All platforms that select COMMON_CLK also select CLKDEV_LOOKUP, therefore just select it in drivers/clk/Kconfig and drop the CLKDEV_LOOKUP all over the place.

| * clk: make COMMON_CLK a visible symbolAhmad Fatoum2024-01-191-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, we expected platforms to select COMMON_CLK if they have a clock controller that's covered by the common clk framework and HAVE_CLK if they have a legacy clock driver. With the addition of SCMI clocks, platforms, especially virtualized ones, that previously didn't need clock support may now want access to them. Instead of having to select COMMON_CLK from such platforms on the off-chance that SCMI clocks may need to be used, just make COMMON_CLK user visible, so it can be selected as needed. As COMMON_CLK needs to conflict with legacy clock support, we also add a symbol for that and start selecting it where appropriate, Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20240118090718.1314156-1-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ARM: layerscape: configure all DMA masters to be cache-coherentAhmad Fatoum2024-01-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream device tree now has /soc/dma-coherent, which breaks USB in Linux v6.1 when kernel is booted with barebox. Fix this by: - setting the snoop bits for the DMA masters, so we properly support Linux >= v6.1 DTs - fixing up cache coherency setting into kernel DT whenever barebox DT has /soc/dma-coherent to support older device trees The latter is done automatically when OF_DMA_COHERENCY is selected, so add the missing snoop bits here.

| | | | | | | | | | | | | | The decision whether to build a 32bit or 64bit barebox has to be made first before anything else, so this makes CONFIG_64BIT a toplevel option without any further dependencies. With this patch we will only present the SoCs/boards which are actually supported by the selected code model in Kconfig. Without this patch it was often possible to select 32bit boards on a 64bit build or vice versa, which resulted in a broken build. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | This allows to build barebox for multiple arch/arm/mach-* for architectures that allow it. To get there we convert machine-y to a list. Architectures that want to support multi-arch must make sure that all boards support multi PBL support (i.e. select HAVE_PBL_MULTI_IMAGES). Also they must make sure that all initcalls can gracefully be executed on other SoCs. Two architectures that fulfil these requirements are added right from the start: i.MX and Rockchip.

Select it from CPU_V8 is detrimental, because subarches may want to select CPU_SUPPORTS_64BIT_KERNEL unconditionally and select CPU_V8 only if 64BIT was chosen.
