2020-05-18common: Drop log.h from common headerSimon Glass
Move this header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05sandbox: Add a new header for the system malloc()Simon Glass
Some files use U-Boot headers but still need to access the system malloc(). Allow this by creating a new asm/malloc.h which can be used so long as U-Boot's malloc.h has not been included. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05sandbox: Rename 'free' variableSimon Glass
This name conflicts with our desire to #define free() to something else on sandbox. Rename it. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-12-15sandbox: Disable mmio by default in testsSimon Glass
When reseting sandbox for tests, disable mmio support since that is the default state. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-08-19sysreset: switch to using SYSRESET_POWER_OFF for poweroffUrja Rannikko
It seems that SYSRESET_POWER_OFF was added recently, and all previous code used SYSRESET_POWER for poweroff. SYSRESET_POWER is supposed to be a PMIC-level power cycle, not a poweroff. (Comment by Simon Glass) SYSRESET_POWER means to do a power reset (removing and reinstating all power) SYSRESET_POWER_OFF means to turn the device off and leave it off Signed-off-by: Urja Rannikko <urjaman@gmail.com> Reviewed-by: Patrick Delaunay <patrick.delaunay@st.com> (Update comment to help understand the patch) Signed-off-by: Kever Yang <kever.yang@rock-chips.com>

At present this returns but it seems better to just exit sandbox immediately. Signed-off-by: Simon Glass <sjg@chromium.org> reset
2018-10-09sandbox: Remove the old memory file laterSimon Glass
When debugging sandbox it is sometimes annoying that the memory file is deleted early on. If sandbox later crashes or we quit (using the debugger), it is not possible to run it again with the same state since the memory file is gone. Remove the old memory file when sandbox exits, instead. Also add debugging showing the memory filename. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-23sandbox: Enhance map_to_sysmem() to handle foreign pointersSimon Glass
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.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2017-06-01sandbox: Add a way to reset sandbox state for testsSimon Glass
Running a new test should reset the sandbox state to avoid tests interferring with each other. Move the existing state-reset code into a function so it can be used from tests. Also update the code to reset the SPI devices and adjust the test code to call it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-26Rename reset to sysresetStephen Warren
The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

2015-11-19sandbox: Add a way to skip time delaysSimon Glass
Some tests are slow due to delays which are unnecessary on sandbox. The worst offender is USB where we lose two seconds. Add a way to disable time delays. Signed-off-by: Simon Glass <sjg@chromium.org>

Add settings for the last reset generated, and the types of resets which are permitted. This will be used for testing. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-02-15sandbox: Return '-c command' exit value as sandbox exit codeJoe Hershberger
When a command is passed into sandbox using the '-c' argument the command is run directly. This is most helpful when running tests (such as test-dm.sh). Previously the exit code was an unused enum. Change it to be the actual return code from the command so that the script calling sandbox can know if the command succeeded (tests passed). Also remove the now completely unused "exit_state" in sandbox. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>

2014-03-17sandbox: Add options to clean up temporary filesSimon Glass
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.

2014-01-08sandbox: Add facility to save/restore sandbox stateSimon Glass
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.

2014-01-08sandbox: Allow reading/writing of RAM bufferSimon Glass
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.

2012-03-12sandbox: add concept of sandbox stateSimon Glass
The state exists through the life of U-Boot. It can be adjusted by command line options and perhaps later through a config file. It is available to U-Boot through state_...() calls (within sandbox code). The primary purpose of this is to contain the "hardware" state. It should only be used by sandbox internal code.
