* siemens:cosmetic, dxr2: rename dxr2 to dracoEgli, Samuel2014-05-13-38/+37
| | | | | | | | | | | | | | The actual board name is draco and dxr2 is the target name. In the future we'll have different targets based on draco board. All changes are purely non-functional and basically rename dxr2 to draco. One style fix in board.c that existed already before.

* siemens: add led cmd for flexible LED controlEgli, Samuel2014-05-13-6/+40
| | | | | | | | | | | | | | | | * remove setting LED in user button function. We want to decouple reading user button and setting LED. This two things need to be done independently. * led cmd can be used to control LEDs that are defined in board file having a led cmd, one can easily set LEDs in u-boot shell. For example bootcmd can be extended to disable status LED before loading kernel.

* arm: am335x: DXR2: Move unconditional LAN9303 reset into commandStefan Roese2014-03-12-7/+19
| | | | | | | | | | | | | The switch HW reset results in a disconnection of the switch port daisy- chain for a few seconds. This is not desired in the normal field use case. So lets remove this switch reset from the normal bootup sequence and move it into a board specific command. This way it can be executed in the development environment when really needed.

* Reduce build timesWolfgang Denk2011-11-03-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-2/+2
| | | | | | | | | | | | | | | | | | | 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) { ...

* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-4/+4
| | | | | | | | | Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* ppc: Enable full relocation to RAMPeter Tyser2009-10-03-5/+0
| | | | | | | | | | | | | The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

* General help message cleanupWolfgang Denk2009-06-12-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
