* sandbox: Set up global data before board_init_f()Simon Glass2014-07-23-1/+0
| | | | | | | | | | | | At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.

* build: define CPU only when arch/${ARCH}/cpu/${CPU} existsMasahiro Yamada2014-07-07-0/+0
| | | | | | | | | | | | | | | | | | | The directory arch/${ARCH}/cpu/${CPU} does not exist in avr32, blackfin, microblaze, nios2, openrisc, sandbox, x86. These architectures have only one CPU type. Defining CPU should not be required for such architectures. This commit allows cpu field (= the 3rd field of boards.cfg) to be kept blank.

* common/board_f: Initialized global data for generic boardYork Sun2014-05-12-0/+1
| | | | | | | | | | | | | Some platforms (tested on mpc85xx, mpc86xx) use global data before calling function baord_inti_f(). The data should not be cleared later. Any arch which uses global data in generic board board_init_f() should define CONFIG_SYS_GENERIC_GLOBAL_DATA.

* sandbox: Add options to clean up temporary filesSimon Glass2014-03-17-1/+2
| | | | | | | | | | | | | | | When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer is preserved in the jump by using a temporary file. Add an option to tell the receiving U-Boot to remove this file when it is no longer needed. Similarly the old U-Boot image is left behind in this case. We cannot delete it immediately since gdb cannot then find its debug symbols. Delete it just before exiting. Together these changes ensure that temporary files are removed both for memory and U-Boot.

* sandbox: Allow Ctrl-C to work in sandboxSimon Glass2014-03-17-0/+24
| | | | | | | | | | | It is useful for Cltl-C to be handled by U-Boot as it is on other boards. But it is also useful to be able to terminate U-Boot with Ctrl-C. Add an option to enable signals while in raw mode, and make this the default. Add an option to leave the terminal cooked, which is useful for redirecting output.

Adjust the common lcd code to support sandbox. For command-line runs we do not want the LCD to be displayed, so add a --show_lcd option to enable it.

* sandbox: Add SDL library for LCD, keyboard, audioSimon Glass2014-03-17-0/+118
| | | | | | | | | | | | | | | | | SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

Add generic infrastructure for doing this using a device tree binary file. This is a flexible tagged file format which is already supported by U-Boot, and it supports hierarchy if needed.

* sandbox: Allow reading/writing of RAM bufferSimon Glass2014-01-08-1/+13
| | | | | | | | | | | | | 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: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-01-0/+1
| | | | | | | | | | | | 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/+3
| | | | | | | | | | | | | | | | | | | | | 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>
* 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/+10
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | This adds simple command-line parsing to sandbox. The idea is that it sets up the state with options provided, and this state can then be queried later, as needed. 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.
