common: Move ARM cache operations out of common.h

2019-12-02T23:24:58Z

These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass Reviewed-by: Daniel Schwierzeck Reviewed-by: Tom Rini

sandbox: Drop 'const' from sandbox_write()

2019-10-27T16:56:41Z

This function writes to its address so the address should not be declared as const. Fix it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

sandbox: Allow use of real I/O with readl(), etc.

2019-10-08T05:57:41Z

At present these functions are stubbed out. For more comprehensive testing with PCI devices it is useful to be able to fully emulate I/O access. Add simple implementations for these. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng [bmeng: change to use 'const void *' in sandbox_write(); cast 'addr' in read/write macros in arch/sandbox/include/asm/io.h; remove the unnecessary cast in readq/writeq in nvme.h] Signed-off-by: Bin Meng

sandbox: remove stray DEBUG

2018-11-21T02:14:22Z

DEBUG should not be defined in production code. Change printf() to debug() where this writes a debug message. Signed-off-by: Heinrich Schuchardt Reviewed-by: Alexander Graf Reviewed-by: Simon Glass

sandbox: Fix setjmp/longjmp

2018-09-23T19:55:30Z

In sandbox, longjmp returns to itself in an endless loop because os_longjmp() calls into longjmp() which is provided by U-Boot which again calls os_longjmp(). Setjmp on the other hand must not return because otherwise the return freees up stack elements that we need during longjmp(). The only straight forward fix that doesn't involve nasty hacks I could find is to directly link against the system setjmp/longjmp implementations. That means we just provide the compiler with hints that the symbol will be available and actually fill them out with versions from libc. This approach should be reasonably platform agnostic Signed-off-by: Alexander Graf Reviewed-by: Simon Glass Signed-off-by: Alexander Graf

sandbox: Enhance map_to_sysmem() to handle foreign pointers

2018-09-23T19:55:30Z

At present map_sysmem() maps an address into the sandbox RAM buffer, return a pointer, while map_to_sysmem() goes the other way. The mapping is currently just 1:1 since a case was not found where a more flexible mapping was needed. PCI does have a separate and more complex mapping, but uses its own mechanism. However this arrange cannot handle one important case, which is where a test declares a stack variable and passes a pointer to it into a U-Boot function which uses map_to_sysmem() to turn it into a address. Since the pointer is not inside emulated DRAM, this will fail. Add a mapping feature which can handle any such pointer, mapping it to a simple tag value which can be passed around in U-Boot as an address. Signed-off-by: Simon Glass Signed-off-by: Alexander Graf

sandbox: Add a setjmp() implementation

2018-06-03T13:27:21Z

Add an implementation of setjmp() and longjmp() which rely on the underlying host C library. Since we cannot know how large the jump buffer needs to be, pick something that should be suitable and check it at runtime. At present we need access to the underlying struct as well.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

libfdt: move headers to and

2018-03-05T15:16:28Z

Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include -> #include #include -> #include Reported-by: Thomas Petazzoni Signed-off-by: Masahiro Yamada

sandbox: Add 64-bit sandbox

2018-02-18T22:53:48Z

To debug device tree issues involving 32- and 64-bit platforms, it is useful to have a generic 64-bit platform available. Add a version of the sandbox that uses 64-bit integers for its physical addresses as well as a modified device tree.
