* global_data: unify global flag definesMike Frysinger2012-08-09-8/+1
| | | | | | | All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sh: modify checkcpu() for SH-4AYoshihiro Shimoda2012-08-08-0/+4

* sh: Add SH7269 device and RSK2+SH7269 boardPhil Edworthy2012-05-28-0/+28
| | | | | | | | | | | | This is an sh2a device (max 266MHz) with FPU, video display controller (VDC), 8 serial ports, 4 I2C channels, 3 CAN ports, SD and on-chip USB. The RSK2+SH7269 board uses the SH7269 processor. It is often referred to as just rsk7269.

| | | | | | | | | | | | | 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.

* Handle most LDSCRIPT setting centrallyScott Wood2011-04-30-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Introduce a new linker flag LDFLAGS_FINALHaiying Wang2011-03-22-1/+1
| | | | | | | | | | | | | | | commit 8aba9dceebb14144e07d19593111ee3a999c37fc Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS breaks the usage of --gc-section to build nand_spl. We still need linker option --gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes the --gc-sections to each uboot image. To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
