* microblaze: Call common console_init_f initialization functionMichal Simek2011-10-10-0/+1
| | | | | | Calling console_init_f enables CTRL+C usage. Signed-off-by: Michal Simek <monstr@monstr.eu>
* unify version_stringAndreas Bießmann2011-07-28-3/+0
| | | | | | | | | | | | 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.

* Replace "FLASH" strings with "Flash" or "flash"Peter Tyser2011-01-19-1/+1
| | | | | | | | There's no compelling reason to have the output on bootup or the "flinfo" command print "flash" in uppercase, so use the proper case where appropriate. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* microblaze: Fix bd_info pointerMichal Simek2011-01-10-3/+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 Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+1
| | | | | | | | | | | | | | | | | | 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 Rigby2010-10-18-9/+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 Denk2010-10-18-1/+1
| | | | | | | | | | | | 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.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* microblaze: Support system with WB cacheMichal Simek2010-04-16-1/+1
| | | | | | | | | | WB cache use different instruction that WT cache but the major code is that same. That means that wdc.flush on system with WT cache do the same thing as before. You need newer toolchain with wdc.flush support. Signed-off-by: Michal Simek <monstr@monstr.eu>
