2020-05-19common: Drop linux/delay.h from common headerSimon Glass1-0/+1
Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-19command: Remove the cmd_tbl_t typedefSimon Glass1-1/+1
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-11-27spi: Remove used spi_initJagan Teki1-2/+0
spi_init used in some areas in tree, but the respective drivers will remove in future patches. So remove the same instances. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
2011-12-06Standalone Apps: Standalone apps should need only exports.h.Mike Partington1-0/+1
Modify exports.h to remove its dependencies on other files, thus enabling standalone apps to require only exports.h from the U-Boot source tree. This appears to be the intent based on the following note: http://lists.denx.de/pipermail/u-boot/2010-January/067174.html Signed-off-by: Mike Partington <mparting@lexmark.com>
2010-07-05Make sure that argv[] argument pointers are not modified.Wolfgang Denk1-1/+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) { ...

2009-09-04atmel_df_pow2: standalone to convert dataflashes to pow2Mike Frysinger1-0/+209
Atmel DataFlashes by default operate with pages that are slightly bigger than normal binary sizes (i.e. many are 1056 byte pages rather than 1024 bytes). However, they also have a "power of 2" mode where the pages show up with the normal binary size. The latter mode is required in order to boot with a Blackfin processor, so many people wish to convert their DataFlashes on their development systems to this mode. This standalone application does just that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
