2010-10-22pci: Add ability to re-enumerate PCI busesJohn Schmoller
Add a new 'pci enum' command which re-enumerates the PCI buses. This command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful in boards with FPGAs connected via PCI/PCIe, boards that support PCI hot-plugging, or during PCI debug. Also enable the 'pci enum' command for X-ES's Freescale-based boards.

2010-07-24cmd_usage(): simplify return code handlingWolfgang Denk
Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...

2009-06-12General help message cleanupWolfgang Denk
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>
2009-01-28Command usage cleanupPeter Tyser
Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>

Fix problem with only partially cleared .bss segment * Patch by Rune Torgersen, 12 May 2003: get PCI to work on a MPC8266ADS board; incorporate change to cpu/mpc8260/pci.c to enable overrides of PCI memory parameters
2003-03-14* Avoid flicker on the TRAB's VFD by synchronizing the enable withwdenk
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100 boards, version 153 for Rev. 200 boards). * Patch by Vladimir Gurevich, 12 Mar 2003: Fix relocation problem of statically initialized string pointers in common/cmd_pci.c * Patch by Kai-Uwe Blöm, 12 Mar 2003: Cleanup & bug fixes for JFFS2 code: - the memory mangement was broken. It caused havoc on malloc by writing beyond the block boundaries. - the length calculation for files was wrong, sometimes resulting in short file reads. - data copying now optionally takes fragment version numbers into account, to avoid copying from older data. See doc/README.JFFS2 for details.
