2019-04-23sandbox: Move pre-console buffer out of the way of tracingSimon Glass
These two buffers currently conflict if tracing is enabled. Move the pre-console buffer and update the documentation. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-04-23sandbox: Improve debugging in initcall_run_list()Simon Glass
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().

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>

2018-02-18sandbox: Add 64-bit sandboxMario Six
To debug device tree issues involving 32- and 64-bit platforms, it is useful to have a generic 64-bit platform available. Add a version of the sandbox that uses 64-bit integers for its physical addresses as well as a modified device tree.

2015-04-18sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger
The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

Implement a bridge between U-Boot's network stack and Linux's raw packet API allowing the sandbox to send and receive packets using the host machine's network interface. This raw Ethernet API requires elevated privileges. You can either run as root, or you can add the capability needed like so: sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2014-05-16sandbox: set sandbox's vendor to nullMasahiro Yamada
Because sandbox is not a real hardware, setting vendor=sandbox is almost meaningless. This commit sets sandbox's vendor field to '-'. It is a good thing that it decreases one level directory hierarchy. The files board/sandbox/sandbox/* have been moved to board/sandbox/*.
