* dm: pci: Add support for PCI driver matchingSimon Glass2015-07-21-4/+4
| | | | | | | | | | | | | | | | | | | At present all PCI devices must be present in the device tree in order to be used. Many or most PCI devices don't require any configuration other than that which is done automatically by U-Boot. It is inefficent to add a node with nothing but a compatible string in order to get a device working. Add a mechanism whereby PCI drivers can be declared along with the device parameters they support (vendor/device/class). When no suitable driver is found in the device tree the list of such devices is consulted to determine the correct driver. If this also fails, then a generic driver is used as before. The mechanism used is very similar to that provided by Linux and the header file defintions are copied from Linux 4.1.

* TSI148: Fix argument parsingBrent Darley2010-10-12-2/+2
| | | | | | | | | | | | | | This patch does 2 things: - Fix the argument number assigned to the vdw (VME data width) value. Previously, a nonexistent 7th arument was read as the vdw variable. - Reduce the size of the argument array for the tsi148 command from 8 to 7. The tsi148 command itself is argument index 0, and the maximum number arguments passed to the command is 6, making a total of 7 for the array.

* 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) { ...
