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: Allow -c argument to provide a command list

2013-05-01T15:17:21Z

This allows passing of entire scripts to sandbox with the -c argument, which is useful for testing. Commands can be delimited with a newline or semicolon. Signed-off-by: Simon Glass

sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host file

2013-05-01T15:17:21Z

With sandbox it is tricky to add an FDT to the image at build time (or later) since we build an ELF file, not a plain binary, and the address space of the whole U-Boot is not accessible in the emulated memory map of sandbox. Sandbox can read files directly from the host, though, so add an option to read an FDT from a host file on start-up. 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

Refactor linker-generated arrays

2013-03-12T22:28:40Z

Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

sandbox: Add a way of obtaining directory listings

2013-03-04T19:19:56Z

This implementation uses opendir()/readdir() to access the directory information and then puts it in a linked list for the caller's use. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

sandbox: Improve sandbox serial port keyboard interface

2013-03-01T03:09:21Z

Implements the tstc() interface for the serial driver. Multiplexing the console between the serial port and a keyboard uses a polling method of checking if characters are available; this means that the serial console must be non-blocking when attempting to read characters.

sandbox: fix compiler warning

2013-03-01T03:09:21Z

Add back return statement to fix compiler warning about control flow reaching end of non void function that was introduced with: e05e5de arm: move C runtime setup code in crt0.S Signed-off-by: Allen Martin Acked-by: Simon Glass

sandbox: Move ram_buf to arch_global_data

2013-02-04T14:05:45Z

Move this field into arch_global_data and tidy up. Signed-off-by: Simon Glass

common: Discard the __u_boot_cmd section

2012-10-22T15:29:42Z

The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h . Signed-off-by: Marek Vasut Cc: Joe Hershberger Cc: Mike Frysinger
