* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

| * sf: move useful messages from debug to printfMike Frysinger2010-06-30-16/+22
| | | | | | | | | | | | | | | | | | | | At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Adding 'extvbus' member in musb_config structure which should be set by all the boards where MUSB interface is using external Vbus supply. Also added ULPI bus control register read/write abstraction for Blackfin processor as it doesn't have ULPI registers.

| * EHCI: zero out QH transfer overlay in ehci_submit_async()Sergei Shtylyov2010-06-29-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI specification suggests) which leads to the controller seeing the "token" field as the previous call has left it, i.e.: - if a timeout occured on the previous call (Active bit left as 1), controller incorrectly tries to complete a previous transaction on a newly programmed endpoint; - if a halt occured on the previous call (Halted bit set to 1), controller just ignores the newly programmed TD(s) and the function then keeps returning error ad infinitum. This turned out to be caused by the wrong orger of the arguments to the memset() call in ehci_alloc(), so the allocated TDs weren't cleared either. While at it, stop needlessly initializing the alternate next TD pointer in the QH transfer overlay... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Acked-by: Remy Bohmer <linux@bohmer.net>

| * | Davinci: SPI performance enhancementsNick Thompson2010-06-22-67/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following restructuring and optimisations increase the SPI read performance from 1.3MiB/s (on da850) to 2.87MiB/s (on da830): Remove continual revaluation of driver state from the core of the copy loop. State can not change during the copy loop, so it is possible to move these evaluations to before the copy loop. Cost is more code space as loop variants are required for each set of possible configurations. The loops are simpler however, so the extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX defined. Unrolling the first copy loop iteration allows the TX buffer to be pre-loaded reducing SPI clock starvation. Unrolling the last copy loop iteration removes testing for the final loop iteration every time round the loop. Using the RX buffer empty flag as a transfer throttle allows the assumption that it is always safe to write to the TX buffer, so polling of TX buffer full flag can be removed.
