* linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-1/+1
| | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>

* sandbox: Remove all drivers before exitSimon Glass2014-07-23-0/+4
| | | | | | | | | | | Drivers are supposed to be able to close down cleanly. To set a good example, make sandbox shut down its driver model drivers and remove them before exit. It may be desirable to do the same more generally once driver model is more widely-used. This could be done during bootm, before U-Boot jumps to the OS. It seems far too early to make this change.

* sandbox: Set up global data before board_init_f()Simon Glass2014-07-23-0/+5
| | | | | | | | | | | | At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.

* sandbox: terminate os_dirent_ls() result listStephen Warren2014-06-23-0/+1
| | | | | | | | | | | Each node in the linked-list that os_dirent_ls() returns has its next pointer set only when the next node is created. For the last node in the list, there is no next node, so this never happens, and the next pointer is never initialized. Explicitly initialize the next pointer so that it isn't dangling. Without this, "sb ls" might crash. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
* sandbox: Add options to clean up temporary filesSimon Glass2014-03-17-10/+22
| | | | | | | | | | | | | | | When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer is preserved in the jump by using a temporary file. Add an option to tell the receiving U-Boot to remove this file when it is no longer needed. Similarly the old U-Boot image is left behind in this case. We cannot delete it immediately since gdb cannot then find its debug symbols. Delete it just before exiting. Together these changes ensure that temporary files are removed both for memory and U-Boot.

* sandbox: Allow Ctrl-C to work in sandboxSimon Glass2014-03-17-6/+35
| | | | | | | | | | | It is useful for Cltl-C to be handled by U-Boot as it is on other boards. But it is also useful to be able to terminate U-Boot with Ctrl-C. Add an option to enable signals while in raw mode, and make this the default. Add an option to leave the terminal cooked, which is useful for redirecting output.

* sandbox: Add LCD driverSimon Glass2014-03-17-0/+9
| | | | | | | | | | | | | Add a simple LCD driver which uses SDL to display the image. We update the image regularly, while still providing for reasonable performance. Adjust the common lcd code to support sandbox. For command-line runs we do not want the LCD to be displayed, so add a --show_lcd option to enable it.

* sandbox: Add SDL library for LCD, keyboard, audioSimon Glass2014-03-17-0/+344
| | | | | | | | | | | | | | | | | SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

* unit-test: make "test -e" test independent of $CWDStephen Warren2014-03-07-0/+5
| | | | | | | | | | | | | | The unit-test for hush's "test -e" currently relies upon being run in the U-Boot build directory, because it tests for the existence of a file that exists in that directory. Fix this by explicitly creating the file we use for the existence test, and deleting it afterwards so that multiple successive unit-test invocations succeed. This required adding an os.c function to erase files. Reported-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

| | | | | | | | | | | | It is often useful to be able to save out the state from a sandbox test run, for analysis or to restore it later to continue a test. Add generic infrastructure for doing this using a device tree binary file. This is a flexible tagged file format which is already supported by U-Boot, and it supports hierarchy if needed.

| | | | | | | | | | | | | It is useful to be able to save and restore the RAM contents of sandbox U-Boot either for setting up tests, for later analysys, or for chaining together multiple tests which need to keep the same memory contents.

At present this output is swallowed so there is no indication what is going wrong.

| | | | | | | | | | | | This file must be compiled with system headers, even if U-Boot has headers of the same name. The existing solution for this is good enough for libfdt, but fails when we have headers like stdint.h in U-Boot.

* sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-01-0/+7
| | | | | | | | | | | | With sandbox it is tricky to add an FDT to the image at build time (or later) since we build an ELF file, not a plain binary, and the address space of the whole U-Boot is not accessible in the emulated memory map of sandbox. Sandbox can read files directly from the host, though, so add an option to read an FDT from a host file on start-up. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-01-0/+5
| | | | | | | | | | | | | | | | | | | | | In many cases, pointers to memory are passed around, and these pointers refer to U-Boot memory, not host memory. This in itself is not a problem. However, in a few places, we cast that pointer back to a ulong (being a U-Boot memory address). It is possible to convert many of these cases to avoid this. However there are data structures (e.g. struct bootm_headers) which use pointers. We could with a lot of effort adjust the structs and all code that uses them to use ulong instead of pointers. This seems like an unacceptable cost, since our objective with sandbox is to minimise the impact on U-Boot code while maximising the features available to sandbox. Therefore, create a map_to_sysmem() function which converts from a pointer to a U-Boot address. This can be used sparingly when needed. Signed-off-by: Simon Glass <sjg@chromium.org>
