* MIPS: board.c: remove manual relocation of env_name_specDaniel Schwierzeck2013-02-15-8/+0
| | | | | | | | Remove the manual relocation of env_name_spec. This has been missed in the previous patch series for introducing dynamic relocation on MIPS. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: add dynamic relocation supportGabor Juhos2013-02-12-9/+0
| | | | | | | | | | | | | | | | | | | | | | The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* MIPS: bootm.c: add support for 'prep' and 'go' subcommandsGabor Juhos2013-01-16-2/+13
| | | | | | | | | | | The bootm command supports subcommands since long time however those subcommands are not yet usable on MIPS. The patch is based on the ARM implementation, and it adds support for the 'prep' and 'go' subcommands only.

* mips: serial: Fix busted manual relocationJoe Hershberger2012-12-12-0/+3

* common: Convert the U-Boot commands to LG-arraysMarek Vasut2012-10-22-2/+2
| | | | | | | | | | | | | | | | | | This patch converts the old method of creating a list of command onto the new LG-arrays code. The old u_boot_cmd section is converted to new u_boot_list_cmd subsection and LG-array macros used as needed. Minor adjustments had to be made to the common code to work with the LG-array macros, mostly the fixup_cmdtable() calls are now passed the ll_entry_start and ll_entry_count instead of linker-generated symbols. The command.c had to be adjusted as well so it would use the newly introduced LG-array API instead of directly using linker-generated symbols.

* net: move bootfile init into eth_initializeMike Frysinger2012-05-15-8/+0

| | | | | | | | | | | This is long over due. All but two net drivers have been converted, but those have now been dropped.

* MIPS: Move timer code to arch/mips/cpu/$(CPU)/Shinya Kuribayashi2011-05-10-99/+0
| | | | | | | | | | | | | | Current timer routines (arch/mips/lib/timer.c) are implemented assuming that MIPS32 coprocessor (CP0) resources, Counter and Compare registers in this case, are available. But this doesn't always work. We need to make sure that all MIPS-based systems don't necessarily use CP0 counter/compare registers as time keeping resources. And some MIPS variant processors might come with different hardware specs with genuine MIPS32 CP0 registers. With this change, each $(CPU)/ directory can have its own timer code.

* 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>

| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions.

* Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-1/+1
| | | | | | | | | | | | | | | | | | | While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...
