2011-11-29x86: Add multiboot headerGraeme Russ
By adding a multiboot header, U-Boot can be loaded by GRUB2. Using GRUB2 to bootstrap U-Boot is useful for using an existing BIOS to get an initial U-Boot port up and running before implementing the low-level reset vector code, SDRAM init, etc. and overwriting the BIOS Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

2011-11-03Reduce build timesWolfgang Denk
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%.

2011-10-05net: drop !NET_MULTI codeMike Frysinger
This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code.

2011-10-05image: push default arch values to arch headersMike Frysinger

2011-10-05console: Implement pre-console bufferGraeme Russ
Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.
2011-08-04Convert ISO-8859 files to UTF-8Albert ARIBAUD
There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2011-07-28unify version_stringAndreas Bießmann
This patch removes the architecture specific implementation of version_string where possible. Some architectures use a special place and therefore we provide U_BOOT_VERSION_STRING definition and a common weak symbol version_string.

2011-04-30Handle most LDSCRIPT setting centrallyScott Wood
Currently, some linker scripts are found by common code in config.mk. Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is sometimes in arch config.mk and sometimes in board config.mk. Some are found using an arch-specific rule for looking in CPUDIR, etc. Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds. Replace all of this -- except for a handful of boards that are actually selecting a linker script in a unique way -- with centralized ldscript finding. If board code specifies LDSCRIPT, that will be used. Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used. If neither of these are specified, then the central config.mk will check for the existence of the following, in order: $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds $(TOPDIR)/$(CPUDIR)/u-boot.lds Some boards (sc3, cm5200, munices) provided their own u-boot.lds that were dead code, because they were overridden by a CPUDIR u-boot.lds under the old powerpc rules. These boards' own u-boot.lds have bitrotted and no longer work -- these lds files have been removed. Signed-off-by: Scott Wood <scottwood@freescale.com> Tested-by: Graeme Russ <graeme.russ@gmail.com>
