Use this new Kconfig instead of OF_BOARD, so we know for sure which boards obtain their devicetree from a prior stage. Leave sandbox alone since it does not. Also don't touch xilinx_versal_virt since it does not have a specific TARGET Kconfig. This option implies OF_BOARD for now, but with future work standard passage may be used instead.

2021-09-15ARM: bcm283x: change the virtual address of the XHCI PCI device baseMarek Szyprowski
Move the XHCI PCI device base up in the virtual address space. This fixes initialization failure observed with newer Raspberry Pi firmware, later than 63b1922311 ("firmware: arm_loader: Update armstubs with those from PR 117). It looks that chosing 0xff800000 as the XHCI PCI device base conflicts with the updated ARM/VideoCore firmware. This also requires to reduce the size of the mapped PCI device region from 8MiB to 4MiB to fit into 32bit address space. This is still enough for the XHCI PCI device.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

Move this out of the common header and include it only where needed.

2018-06-14efi_loader: Convert runtime reset from switch to if statementsAlexander Graf
We currently handle the UEFI runtime reset / power off case handling via a switch statement. Compilers (gcc in my case) may opt to handle these via jump tables which they may conveniently put into .rodata which is not part of the runtime section, so it will be unreachable when executed. Fix this by just converting the switch statement into an if/else statement. It produces smaller code that is faster and also correct because we no longer refer .rodata from efi runtime code.

2018-05-07arm: v7: Kconfig: Rename CPU_V7 as CPU_V7ALokesh Vutla
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

The bcm283x family of SoCs have a GPIO controller that also acts as pinctrl controller. This patch introduces a new pinctrl driver that can actually properly mux devices into their device tree defined pin states and is now the primary owner of the gpio device. The previous GPIO driver gets moved into a subdevice of the pinctrl driver, bound to the same OF node. That way whenever a device asks for pinctrl support, it gets it automatically from the pinctrl driver and GPIO support is still available in the normal command line phase.
