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

2013-02-04T14:05:45Z

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

sandbox: Add cpu files

2011-10-17T21:53:46Z

This is an initial implementation with all functions defined but not working. The lds file is very simple since we can mostly rely on the linker defaults. Signed-off-by: Simon Glass
