* sandbox: Add -i option to enter interactive modeSimon Glass2014-01-08-1/+13
| | | | | | | | | | | | Normally when U-Boot starts with a command (-c option) it quits when the command completes. Normally this is what is requires, since the test is likely complete. Provide an option to jump into the console instead, so that debugging or other tasks may be performed before quitting.

* sandbox: Allow the console to work earlierSimon Glass2014-01-08-0/+11
| | | | | | | | | | | | | With sandbox, errors and problems may be reported before console_init_f() is executed. For example, an argument may not parse correctly or U-Boot may panic(). At present this output is swallowed so there is no indication what is going wrong. Adjust the console to deal with a very early sandbox setup, by detecting that there is no global_data yet, and calling os functions in that case.

* sandbox: Implement the bootm command for sandboxSimon Glass2014-01-08-2/+15
| | | | | | | | | | 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.

| | | | | | | | | | | | Sandbox uses an emulated memory map which is quite small. We don't need the CONFIG_PHYS_64BIT option since we can address memory with a 32-bit offset into our ram_buf.

* sandbox: Use system headers first for sandbox's os.cSimon Glass2013-11-21-2/+4
| | | | | | | | | | | | This file must be compiled with system headers, even if U-Boot has headers of the same name. The existing solution for this is good enough for libfdt, but fails when we have headers like stdint.h in U-Boot. Use -idirafter instead of -I, and remove the -nostdinc and other things that we don't want for this file. The best way to do this is to keep a copy of the original flags, rather than trying to filter them later. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | Support tracing on sandbox by adding suitable CONFIG options. To enable it, compile U-Boot with FTRACE=1.

* sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-01-0/+8
| | | | | | | | | | | | 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 <sjg@chromium.org>

* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-01-0/+8
| | | | | | | | | | | | | | | | | | | | | 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 <sjg@chromium.org>

| * Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Introduce generic link section.h symbol filesSimon Glass2013-03-15-0/+2
|/ | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass2013-02-28-0/+11
| | | | | | | | | | | | | | | | | | | | | | Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro, pointers are automatically gathered up in a special section, and then the core code takes care of gathering them up and processing at runtime.

| | | | | | | | | | | | | | | | | | | | | | | U-boot itself generally builds with -nostdinc. This is because the bootloader needs to be completely standalone. In the sandbox arch though, we need a little bit of code to glue the u-boot world to the host operating system, and we need to be able to access the host libc's headers in order to do so. Currently, we're using -I/usr/include to workaround the global -nostdinc, but that doesn't work for everyone and for all headers. Instead, let's filter out -nostdinc when building the os.c code.
