* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* fsl: improve the PIXIS code and fix a few bugsTimur Tabi2010-04-07-128/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

* General help message cleanupWolfgang Denk2009-06-12-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Command usage cleanupPeter Tyser2009-01-28-2/+2

* Make pixis_set_sgmii more general to support MPC85xx boards.Liu Yu2008-10-18-3/+19
| | | | | | | | | | | | The pixis sgmii command depend on the FPGA support on the board, some 85xx boards support SGMII riser card but did not support this command, define CONFIG_PIXIS_SGMII_CMD for those boards which support the sgmii command. Not like 8544, 8572 has 4 eTsec so that the other two's pixis bits are not supported by 8544. Therefor, define PIXIS_VSPEED2_MASK and PIXIS_VCFGEN1_MASK in header file for both boards.

* Add pixis_set_sgmii commandAndy Fleming2008-09-02-0/+55
| | | | | | | | | | | | | | | | | | The 8544DS and 8572DS platforms support an optional SGMII riser card to expose ethernet over an SGMII interface. Once the card is in, it is also necessary to configure the board such that it uses the card, rather than the on-board ethernet ports. This can either be done by flipping dip switches on the motherboard, or by modifying registers in the pixis. Either way requires a reboot. This adds a command to allow users to choose which ports are routed through the SGMII card, and which through the onboard ports. It also allows users to revert to the current switch settings. This code does not work on the 8572, as the PIXIS is different. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | 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>

* Add PIXIS FPGA support for MPC8641HPCN board.Haiying Wang2007-04-09-0/+472
Move the 8641HPCN's PIXIS code to the new directory board/freescale/common/ as it will be shared by future boards not in the same processor family. Write a "pixis_reset" command that utilizes the FPGA reset sequencer to support alternate soft-reset options such as using the "alternate" flash bank, enabling the watch dog, or choosing different CPU frequencies.
