sandbox: sdl: Add an option to double the screen size

2020-02-06T02:33:46Z

On high-DPI displays U-Boot's LCD window can look very small. Add a -K flag to expand it to make things easier to read, while still using the existing resolution internally. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

sandbox: Add a new header for the system malloc()

2020-02-06T02:33:46Z

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

sandbox: Sort the help options

2020-02-06T02:33:46Z

At present options are presented in essentially random order. It is easier to browse them if they are sorted into alphabetical order. Adjust the help function to handle this. Signed-off-by: Simon Glass

cli: Make the sandbox board_run_command the default

2020-02-06T02:33:46Z

If CONFIG_CMDLINE=n, common/cli.c calls board_run_command. This fails to link on most architectures. However, the sandbox architecture has an implementation which we can use. Signed-off-by: Sean Anderson

common: Move command functions out of common.h

2019-12-02T23:25:02Z

Move these functions into the command.h header file which is a better fit. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

sandbox: Add a -T flag to use the test device tree

2019-10-08T05:57:41Z

U-Boot already supports using -D to indicate that it should use the normal device tree. It is sometimes useful to run with the test device tree, e.g. when running a test. Add a -T option for this along with some documentation. It can be used like this: /tmp/b/sandbox/u-boot -T -c "ut dm pci_busdev" (this will use /tmp/b/sandbox/arch/sandbox/dts/test.dtb as the DT) Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng

sandbox: Drop the printf() in setup_ram_buf()

2019-04-24T02:26:43Z

This was really intended for debugging. Drop it. Signed-off-by: Simon Glass

sandbox: Improve debugging in initcall_run_list()

2019-04-24T02:26:43Z

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: Zero the ram buffer on startup

2018-12-05T13:01:34Z

At present the RAM buffer is not inited unless it is read from a file, likely produced by an earlier phase of U-Boot. This causes valgrind warnings whenever the RAM buffer is used. Correct this by initing it if needed. Signed-off-by: Simon Glass

sandbox: Add a new 'sb' command

2018-11-26T13:25:36Z

The old 'sb' command was deprecated in 2015 and replaced with 'host'. It is useful to be able to access some internal sandbox state, particularly for testing. Resurrect the old command and provide a way to print some basic state information (currently just the arguments to sandbox). Signed-off-by: Simon Glass
