| | | | | | | | | | | | | This is minimum code required to be able to use device-tree for u-boot initialization. Currently only for device driver initialization. Linker script change ensures DTB to be aligned for both options CONFIG_OF_EMBED and CONFIG_OF_SEPARATE.

* microblaze: avoid interrupt race conditionsStephan Linz2012-02-231-2/+2
| | | | | | | | | | | | | | The interrupt acknowledge action have to run after the registered interrupt handler. So we have a chance to bear out the corresponding interrupt request in the corresponding controller hardware. With this reordering, we optain a proper interrupt handling for level triggered interrupt sources -- for example the new axi_timer v1.02.a introduced in ISE 13.2.

* console: Implement pre-console bufferGraeme Russ2011-10-051-0/+3
| | | | | | | | | | | | | 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.

* microblaze: Fix bd_info pointerMichal Simek2011-01-101-3/+5
| | | | | | | | | | | | | | | | | | | | | Patch "Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value" (sha1: 25ddd1fb0a2281b182529afbc8fda5de2dc16d96) introduce GENERATED_GBL_DATA_SIZE which is sizeof aligned gd_t (currently 0x40). Microblaze configs used 0x40(128) because this place also contained board info structure which lies on the top of ram. U-Boot is placed to the top of the ram (for example 0xd7ffffff) and bd structure was moved out of ram. This patch is fixing this scheme with GENERATED_BD_INFO_SIZE which swap global data and board info structures. For example: Current: gd 0xd7ffffc0, bd 0xd8000000 Fixed: gd 0xd7ffffc0, bd 0xd7ffff90 Signed-off-by: Michal Simek <monstr@monstr.eu>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-172-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-291-3/+0
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-263-2/+3
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* FDT: only call boot_get_fdt from generic codeJohn Rigby2010-10-181-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | All arches except nios2 and microblaze call boot_get_fdt from bootm_start in common/cmd_bootm.c. Having nios2 and microblaze do so as well removes code from their respective do_bootm_linux routines and allows removal of a nasty ifdef from bootm_start. In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first. This is already the case for nios2.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-182-3/+3
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.
