2021-03-02sandbox: Avoid using malloc() for system stateSimon Glass
This state is not accessible to the running U-Boot but at present it is allocated in the emulated SDRAM. This doesn't seem very useful. Adjust it to allocate from the OS instead. The RAM buffer is currently not freed, but should be, so add that into state_uninit(). Update the comment for os_free() to indicate that NULL is a valid parameter value. Note that the strdup() in spl_board_load_image() is changed as well, since strdup() allocates memory in the RAM buffer. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-03-02sandbox: Add os_realloc()Simon Glass

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>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2021-01-05sandbox: remove ram buffer file when U-Boot is loaded by SPLPatrick Delaunay
Update management of "--rm_memory" sandbox's option and force this option when U-Boot is loaded by SPL in os_spl_to_uboot() and remove the ram file after reading in main() as described in option help message: "Remove memory file after reading". This patch avoids that the file "/tmp/u-boot.mem.XXXXXX" [created in os_jump_to_file() when U-Boot is loaded by SPL] is never deleted because state_uninit() is not called after U-Boot execution (CtrlC or with running pytest for example). This issue is reproduced by > build-sandbox_spl/spl/u-boot-spl and CtrlC in U-Bot console > make qcheck One temp file is created after each SPL and U-Boot execution (7 tims in qcheck after test_handoff.py, test_ofplatdata.py, test_spl.py execution).

Up to now the sandbox would shutdown upon a cold reset request. Instead it should be reset. In our coding we use static variables like LIST_HEAD(efi_obj_list). A reset can occur at any time, e.g. via an UEFI binary calling the reset service. The only safe way to return to an initial state is to relaunch the U-Boot binary.

2020-10-29dm: test: Add a way to run SPL testsSimon Glass
Add a -u flag for U-Boot SPL which requests that unit tests be run. To make this work, export dm_test_main() and update it to skip test features that are not used with of-platdata. To run the tests: $ spl/u-boot-spl -u U-Boot SPL 2020.10-rc5 (Oct 01 2020 - 07:35:39 -0600) Running 0 driver model tests Failures: 0 At present there are no SPL unit tests. Note that there is one wrinkle with these tests. SPL has limited memory available for allocation. Also malloc_simple does not free memory (free() is a nop) and running tests repeatedly causes driver-model to reinit multiple times and allocate memory. Therefore it is not possible to run more than a few tests at a time. One solution is to increase the amount of malloc space in sandbox_spl. This is not a problem for pytest, since it runs each test individually, so for now this is left as is. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-04-16sandbox: also restore terminal settings when killed by SIGINTRasmus Villemoes
Hitting Ctrl-C is a documented way to exit the sandbox, but it is not actually equivalent to the reset command. The latter, since it follows normal process exit, takes care to reset terminal settings and restoring the O_NONBLOCK behaviour of stdin (and, in a terminal, that is usually the same file description as stdout and stderr, i.e. some /dev/pts/NN). Failure to restore (remove) O_NONBLOCK from stdout/stderr can cause very surprising and hard to debug problems back in the terminal. For example, I had "make -j8" consistently failing without much information about just exactly what went wrong, but sometimes I did get a "echo: write error". I was at first afraid my disk was getting bad, but then a simple "dmesg" _also_ failed with write error - so it was writing to the terminal that was buggered. And both "make -j8" and dmesg in another terminal window worked just fine. So install a SIGINT handler so that if the chosen terminal mode (cooked or raw-with-sigs) means Ctrl-C sends a SIGINT, we will still call os_fd_restore(), then reraise the signal and die as usual from SIGINT.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
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.
