sandbox: Remove all drivers before exit

2014-07-23T13:07:24Z

Drivers are supposed to be able to close down cleanly. To set a good example, make sandbox shut down its driver model drivers and remove them before exit. It may be desirable to do the same more generally once driver model is more widely-used. This could be done during bootm, before U-Boot jumps to the OS. It seems far too early to make this change.

Use a const pointer for map_to_sysmem()

2014-03-18T02:05:45Z

This function does not actually change the pointer contents, so use const so that functions which have a const pointer do not need to cast. Signed-off-by: Simon Glass

sandbox: Allow reading/writing of RAM buffer

2014-01-09T00:25:03Z

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: Implement the bootm command for sandbox

2014-01-09T00:24:42Z

When sandbox does a 'bootm' to run a kernel we cannot actually execute it. So just exit sandbox, which is essentially what U-Boot does on other archs. Also, allow sandbox to use bootm on any kernel, so that it can be used to test booting of kernels from any architecture. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: Support trace feature

2013-06-26T14:16:41Z

Support tracing on sandbox by adding suitable CONFIG options. To enable it, compile U-Boot with FTRACE=1. The timer functions are marked to skip tracing, since these are called from the tracing code itself, and we want to avoid an infinite loop. Signed-off-by: Simon Glass

sandbox: Provide a way to map from host RAM to U-Boot RAM

2013-05-01T15:17:21Z

In many cases, pointers to memory are passed around, and these pointers refer to U-Boot memory, not host memory. This in itself is not a problem. However, in a few places, we cast that pointer back to a ulong (being a U-Boot memory address). It is possible to convert many of these cases to avoid this. However there are data structures (e.g. struct bootm_headers) which use pointers. We could with a lot of effort adjust the structs and all code that uses them to use ulong instead of pointers. This seems like an unacceptable cost, since our objective with sandbox is to minimise the impact on U-Boot code while maximising the features available to sandbox. Therefore, create a map_to_sysmem() function which converts from a pointer to a U-Boot address. This can be used sparingly when needed. Signed-off-by: Simon Glass

sandbox: Move ram_buf to arch_global_data

sandbox: Add OS dependent layer

2011-10-17T21:56:58Z

We want to keep all OS-dependent code in once place, with a simple interface to U-Boot. For now, this is that place. Signed-off-by: Simon Glass
