* sandbox: Drop os_realloc()Simon Glass2020-02-051-21/+1
| | | | | | Due to recent changes this function is no-longer used. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Improve debugging in initcall_run_list()Simon Glass2019-04-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present if one of the initcalls fails on sandbox the address printing is not help, e.g.: initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96) This is because U-Boot gets relocated high into memory and the relocation offset (gd->reloc_off) does not work correctly for sandbox. Add support for finding the base address of the text region (at least on Linux) and use that to set the relocation offset. This makes the output better: initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96) Then you use can use grep to see which init call failed, e.g.: $ grep 0000000000048134 u-boot.map stdio_add_devices Of course another option is to run it with a debugger such as gdb: $ gdb u-boot ... (gdb) br initcall.h:41 Breakpoint 1 at 0x4db9d: initcall.h:41. (2 locations) Note that two locations are reported, since this function is used in both board_init_f() and board_init_r().

* sandbox: Add a function to read a host fileSimon Glass2018-11-201-0/+14
| | | | | | | | Add a way to read a file from the host filesystem. This can be useful for reading test data, for example. Also fix up the writing function which was not the right version, and drop the debugging lines. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Restore blocking I/O on exitSimon Glass2018-10-091-10/+0
| | | | | | | | | | | | At present sandbox sets non-blocking I/O as soon as any input is read from the terminal. However it does not restore the previous state on exit. Fix this and drop the old os_read_no_block() function. This means that we always enable blocking I/O in sandbox (if input is a terminal) whereas previously it would only happen on the first call to tstc() or getc(). However, the difference is likely not important. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Add a way to write data to the host filesystemSimon Glass2018-10-091-0/+13
| | | | | | | | For debugging it is sometimes useful to write out data for inspection using an external tool. Add a function which can write this data to a given file. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Support file truncation with os_open()Simon Glass2018-10-091-0/+1
| | | | | | | At present files are not truncated on writing. This is a useful feature. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Unprotect DATA regions in bus testsSimon Glass2018-10-081-0/+12
| | | | | | | | | | | | On my Ubuntu 18.04.1 machine two driver-model bus tests have started failing recently. The problem appears to be that the DATA region of the executable is protected. This does not seem correct, but perhaps there is a reason. To work around it, unprotect the regions in these tests before accessing them. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Fix setjmp/longjmpAlexander Graf2018-09-231-21/+0
| | | | | | | | | | | | | | | | | | | | | 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 <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
* sandbox: Add support for calling abort()Simon Glass2018-09-231-0/+4
| | | | | | | | | | This function is useful to signal that the application needs to exit immediate. It can be caught with a debugger (e.g. gdb). Add a stub for it so that it can be called from within sandbox when an internal error occurs. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
* sandbox: Add a setjmp() implementationSimon Glass2018-06-031-0/+21
| | | | | | | | | | 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 styleTom Rini2018-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | 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>
* Revert "sandbox: remove os_putc() and os_puts()"Simon Glass2017-12-071-0/+20
| | | | | | | | | | | | | While sandbox works OK without the special-case code, it does result in console output being stored in the pre-console buffer while sandbox starts up. If there is a crash or a problem then there is no indication of what is going on. For ease of debugging it seems better to revert this change. This reverts commit 47b98ad0f6779485d0f0c14f337c3eece273eb54. Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: Allow chaining from SPL to U-Boot properSimon Glass2016-07-141-0/+25
| | | | | | | | SPL is expected to load and run U-Boot. This needs to work with sandbox also. Provide a function to locate the U-Boot image, and another to start it. This allows SPL to function on sandbox as it does on other archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Tidy up terminal restoreSimon Glass2015-06-041-0/+8

* sandbox: Allow Ctrl-C to work in sandboxSimon Glass2014-03-171-1/+5
| | | | | | | | | | | 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.

* unit-test: make "test -e" test independent of $CWDStephen Warren2014-03-071-0/+8
| | | | | | | | | | | | | | 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>

* sandbox: Allow reading/writing of RAM bufferSimon Glass2014-01-081-0/+16
| | | | | | | | | | | | | 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. Add a function to provide a memory file for U-Boot. This is read on start-up and written when shutting down. If the file does not exist on start-up, it will be created when shutting down.

* sandbox: Allow the console to work earlierSimon Glass2014-01-081-0/+20
| | | | | | | | | | | | | With sandbox, errors and problems may be reported before console_init_f() is executed. For example, an argument may not parse correctly or U-Boot may panic(). At present this output is swallowed so there is no indication what is going wrong. Adjust the console to deal with a very early sandbox setup, by detecting that there is no global_data yet, and calling os functions in that case.

* sandbox: add getopt supportSimon Glass2012-03-121-0/+14
| | | | | | | | | | | | | | | This adds simple command-line parsing to sandbox. The idea is that it sets up the state with options provided, and this state can then be queried later, as needed. New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro, pointers are automatically gathered up in a special section, and then the core code takes care of gathering them up and processing at runtime.
