dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

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
