* Add trace librarySimon Glass2013-06-26-0/+4
| | | | | | | | | Add a library which supports tracing of execution using built-in gcc features and a microsecond timer. This can be used to record a list of function which are executed, along with a timestamp for each. Later this information can be sent to the host for processing.

* main: Separate out the two abortboot() functionsSimon Glass2013-06-04-3/+0
| | | | | | | | | | | | | There are two implementations of abortboot(). Turn these into two separate functions, and create a single abortboot() which calls either one or the other. Also it seems that nothing uses abortboot() outside main, so make it static. At this point there is no further use of CONFIG_MENU in main.c.

| | | | | | | | | | The Freescale MPC8220 Power Architecture processors have long reached EOL; Freescale does not even list these any more on their web site.

* image: Add device tree setup to image librarySimon Glass2013-05-14-0/+10
| | | | | | | | | | | This seems to be a common function for several architectures, so create a common function rather than duplicating the code in each arch. Also make an attempt to avoid introducing #ifdefs in the new code, partly by removing useless #ifdefs around function declarations in the image.h header. Signed-off-by: Simon Glass <sjg@chromium.org>

* Add getenv_hex() to return an environment variable as hexSimon Glass2013-05-01-0/+13
| | | | | | | | This conversion is required in a number of places in U-Boot. Add a standard function to provide this feature, so we avoid all the different variations in the way it is coded. 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/+5
| | | | | | | | | | | | | | | | | | | | | 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>

* sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass2013-02-28-0/+12
| | | | | | | | | | | | | | | | | | | | | | 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.

* Update print_buffer() to use constSimon Glass2013-02-28-1/+2
| | | | | | | | The buffer cannot be changed by this function, so change the buffer pointer to a const. This allows callers with const pointer to use the function without a cast. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add option to display customised memory informationSimon Glass2013-01-10-0/+9
| | | | | | | | | | | | | | | Some boards want to report more than just memory size. For example, it might be useful to display the memory type (DDR2, DDR3) or manufacturer. Add a weak function to support this requirement, accessed through a new 'meminfo' command. Any example of the DRAM: output is below, just for illustration: SMDK5250 # meminfo DRAM: 2 GiB Elpida DDR3 @ 800MHz Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: move C runtime setup code in crt0.SAlbert ARIBAUD2013-01-08-1/+1
| | | | | | | | | | | | | | | | | | Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)).
