2013-07-12blackfin: x86: bootm: Handle PREP stage of bootmSimon Glass
The OS function is now always called with the PREP stage. Adjust the remaining bootm OS functions to deal with this correctly. Signed-off-by: Simon Glass <[email protected]>
2010-08-11Blackfin: shutdown video DMA when booting LinuxMichael Hennerich
In case there is no frame buffer driver present in Linux to hand over the PPI LCD DMA upon boot, the DMA initiated by u-boot to display the splash screen runs unattended. Therefore always stop the video driver in u-boot before starting Linux. If people don't want this behavior, then they can simply stub out the video_stop() function in their board video driver.

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) { ...

2010-04-13Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser
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 <[email protected]>
