* libfdt: Add overlay application functionMaxime Ripard2016-08-20-0/+5
| | | | | | | | | | The device tree overlays are a good way to deal with user-modifyable boards or boards with some kind of an expansion mechanism where we can easily plug new board in (like the BBB, the Raspberry Pi or the CHIP). Add a new function to merge overlays with a base device tree. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* lib: Enable private libgcc by defaultMarek Vasut2016-06-02-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch decouples U-Boot binary from the toolchain on systems where private libgcc is available. Instead of pulling in functions provided by the libgcc from the toolchain, U-Boot will use it's own set of libgcc functions. These functions are usually imported from Linux kernel, which also uses it's own libgcc functions instead of the ones provided by the toolchain. This patch solves a rather common problem. The toolchain can usually generate code for many variants of target architecture and often even different endianness. The libgcc on the other hand is usually compiled for one particular configuration and the functions provided by it may or may not be suited for use in U-Boot. This can manifest in two ways, either the U-Boot fails to compile altogether and linker will complain or, in the much worse case, the resulting U-Boot will build, but will misbehave in very subtle and hard to debug ways.

* fdt: Allow libfdt to be used in SPLSimon Glass2016-03-14-0/+10
| | | | | | | | | | | | 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.

* lib/tiny-printf.c: Add tiny printf function for space limited environmentsStefan Roese2015-11-23-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Here a comparison for the db-mv784mp-gp (Marvell AXP) SPL: Without this patch: 58963 18536 1928 79427 13643 ./spl/u-boot-spl With this patch: 56542 18536 1956 77034 12cea ./spl/u-boot-spl Note: To make it possible to compile tiny-printf.c instead of vsprintf.c when CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are moved from common/console.c into vsprintf.c in this patch.

* Add support for LZ4 decompression algorithmJulius Werner2015-10-11-0/+18
| | | | | | | | | | | | | | | This patch adds support for LZ4-compressed FIT image contents. This algorithm has a slightly worse compression ration than LZO while being nearly twice as fast to decompress. When loading images from a fast storage medium this usually results in a boot time win. Sandbox-tested only since I don't have a U-Boot development system set up right now. The code was imported unchanged from coreboot where it's proven to work, though. I'm mostly interested in getting this recognized by mkImage for use in a downstream project. Signed-off-by: Julius Werner <jwerner@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

* Allow CONFIG_REGEX to be disabled when CONFIG_NETJoe Hershberger2015-07-08-0/+1
| | | | | | | | | | | Instead of selecting REGEX when NET is enabled, make it the default, but allow boards that are tiny to disable it and lose functionality on all but the first Ethernet adapter. cm-bf548, bf538f-ezkit, and bf533-stamp need this.

* blackfin: fix undefined reference to srand and randMasahiro Yamada2015-06-11-1/+3
| | | | | | | | | | | | | | | | | | | | | Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies) accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards. Prior to that commit, those boards defined CONFIG_LIB_RAND, but not CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have touched them, but in fact it ripped CONFIG_LIB_RAND off from all the header files, which caused undefined reference to srand and rand. CONFIG_LIB_RAND=y must be revived for such boards. BTW, this commit indeed makes it better, but even with this fix, three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not build due to region 'ram' overflowed error. This was cause by commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs) because CMD_NET selects NET, and NET selects REGEX. Eventually, some boards were newly enabled with CONFIG_REGEX, increasing the memory footprint. A patch is expected to fix the build error.
