config: Always use GNU ld 2012-08-10T21:26:10+00:00 Khem Raj raj.khem@gmail.com 2012-08-02T06:19:34+00:00 7cb714a57837f1352d737ae07b56a5ce47c40431 This patch makes sure that we always use the GNU ld. U-Boot uses certain construct e.g. OVERLAY which are not implemented in gold therefore it always needs GNU ld for linking. It works well if default linker in toolchain is GNU ld but in some cases we can have gold to be the default linker and also ship GNU ld but not as default in such cases its called $(PREFIX)ld.bfd, with this patch we make sure that if $(PREFIX)ld.bfd exists than we use that for our ld. This way it does not matter what the default ld is. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Khem Raj <raj.khem@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org>

Both images are created using mkimage (crc etc), so that the ROM bootloader can check its integrity. Padding needs to be done to the SPL image (with mkimage header) and not the binary. Otherwise the resulting image which is loaded/copied by the ROM bootloader to SRAM doesn't fit. The resulting image containing both U-Boot images is called u-boot.spr.

Reduce build times 2011-11-03T19:44:58+00:00 Wolfgang Denk wd@denx.de 2011-11-01T20:54:02+00:00 cca4e4aec1fe52e5ecd15e3cebdbb36e2f254220 U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.

fdt: Add support for embedded device tree (CONFIG_OF_EMBED) 2011-10-26T19:38:59+00:00 Simon Glass sjg@chromium.org 2011-10-15T05:48:21+00:00 bbb0b128c3956ac549471addc314702fbe0ace63 This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path.
