2016-03-14lib/crc16.c: Rename cyg_crc16() to crc16_ccitt() and add crc start valueStefan Roese
The original name of this function is unclear. This patch renames this CRC16 function to crc16_ccitt() matching its name with its implementation. To make the usage of this function more flexible, lets add the CRC start value as parameter to this function. This way it can be used by other functions requiring different start values than 0 as well. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>

2016-03-14fdt: Allow libfdt to be used in SPLSimon Glass
Add an option to enable libfdt in SPL. This can be useful when decoding FIT files in SPL. We need to make sure this option is not enabled in SPL by this change. Also this option needs to be enabled in host builds. Si add a new IMAGE_USE_LIBFDT #define which can be used in files that are built on the host but must also build for U-Boot and SPL.

2016-03-14Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass
There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

2016-03-14libfdt: Add a function to write a property placeholderSimon Glass
The existing function to add a new property to a tree being built requires that the entire contents of the new property be passed in. For some applications it is more convenient to be able to add the property contents later, perhaps by reading from a file. This avoids double-buffering of the contents. Add a new function to support this and adust the existing fdt_property() to use it. Signed-off-by: Simon Glass <sjg@chromium.org>

In some cases the timer must be accessible before driver model is active. Examples include when using CONFIG_TRACE to trace U-Boot's execution before driver model is set up.

2016-02-15Makefile: remove BUILD_TAG from KBUILD_CFLAGSStephen Warren
If BUILD_TAG is part of KBUILD_CFLAGS, then any time the value changes, all files get rebuilt. In a continuous integration environment, the value will change every build. This wastes time, assuming that incremental builds would otherwise occur. To solve this, remove BUILD_TAG from KBUILD_CFLAGS and add it to CFLAGS for just the one file that uses it. This does have the disadvantage that if any other files want to use the flag, we'll need to duplicate this custom CFLAGS setup logic. However, it seems unlikely we'll need this. An alternative would be to add BUILD_TAG to the "local version" and remove the special case code from display_options.c. However, that would affect the format of the U-Boot signon message, which may negatively affect people looking for specific data there. The approach of using file-specific CFLAGS was suggested by Masahiro Yamada.

2016-02-09gunzip: remove avail_in recalculationStephen Warren
Current, the following passes: ./u-boot -d arch/sandbox/dts/test.dtb -c 'ut_image_decomp' but the following fails: ./u-boot -d arch/sandbox/dts/test.dtb -c 'ut dm; ut_image_decomp' This is because the gunzip code reads input data beyond the end of its input buffer. In the first case above, this data just happens to be 0, which just happens to trigger gzip to signal the error the decompression unit test expects. In the second case above, the "ut dm" test has written data to the accidentally-read memory, which causes the gzip code to take a different path and so return a different value, which triggers the test failure. The cause of gunzip reading past its input buffer is the re-calculation of s.avail_in in zunzip(), since it can underflow. Not only is the formula non-sensical (it uses the delta between two output buffer pointers to calculate available input buffer size), it also appears to be unnecessary, since the gunzip code already maintains this value itself. This patch removes this re-calculation to avoid the underflow and redundant work. The loop exit condition is also adjusted so that if inflate() has consumed the entire input buffer, without indicating returning Z_STREAM_END (i.e. decompression complete without error), an error is raised. There is still opportunity to simplify the code here by splitting up the loop exit condition into separate tests. However, this patch makes the minimum modifications required to solve the problem at hand, in order to keep the Acked-by: Kees Cook <keescook@chromium.org> diff simple. I am not entirely convinced that the loop in zunzip() is necessary at all. It could only be useful if inflate() can return Z_BUF_ERROR (which typically means that it needs more data in the input buffer, or more space in the output buffer), even though Z_FINISH is set /and/ the full input is available in the input buffer /and/ there is enough space to store the decompressed output in the output buffer. The comment in zlib.h after the prototype of inflate() implies this is never the case. However, I assume there must have been some reason for introducing this loop in the first place, as part of commit "Fix gunzip to work for any gziped uImage size". This patch is similar to the earlier b75650d84d4b "gzip: correctly bounds-check output buffer", which corrected a similar issue for s.avail_out.

This patch adds a small printf() version that supports all basic formats. Its intented to be used in U-Boot SPL versions on platforms with very limited internal RAM sizes. To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This will result in the SPL using this tiny function and the main U-Boot still using the full-blown printf() function. This code was copied from: http://www.sparetimelabs.com/printfrevisited With mostly only coding style related changes so that its checkpatch clean. The size reduction is about 2.5KiB.
