2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
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>
2019-12-02common: Move interrupt functions into a new headerSimon Glass
These functions do not use driver model but are fairly widely used in U-Boot. But it is not clear that they will use driver model anytime soon, so we don't want to label them as 'legacy'. Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it is widely used in U-Boot already. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-10-23nios2: map physical address to uncached virtual addressThomas Chou
Add ioremap() to map physical address to uncached virtual address. We need this to convert the reg address from the device tree. The order of headers inclusion in interrupts.c is changed because common.h will include board header that contains IO_REGION_BASE. In the future, the IO_REGION_BASE should be decided from the device tree. tree Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2014-08-30nios2: divide nios2-io.h into each specific drivers and remove itThomas Chou
The nios2-io.h defines hardware registers and bits of several FPGA IP cores. It could be divided in to the specific drivers, including altera timer, altera sysid, altera uart and altera jtag uart. The altera pio and altera spi drivers use their own hardware definitions. The removal of nios2-io.h will help modularity and maintenance. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

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) { ...
