2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass1-0/+2
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>

2019-01-15riscv: replace use of callee-saved register in standaloneLukas Auer1-5/+5
Register x19 (s3) is a callee-saved register. It must not be used to load and jump to exported functions without saving it beforehand. Replace it with t0, a temporary and caller-saved register. Change the code comment to reflect this and fix it to correctly list gp as the register with the pointer to global data.

2017-07-06avr32: Retire AVR32 for goodAndy Shevchenko1-13/+0
AVR32 is gone. It's already more than two years for no support in Buildroot, even longer there is no support in GCC (last version is heavily patched 4.2.4). Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully). There is no good point to keep this support in U-Boot either.

2015-01-29Export redesignMartin Dorwig1-31/+33
this is an atempt to make the export of functions typesafe. I replaced the jumptable void ** by a struct (jt_funcs) with function pointers. The EXPORT_FUNC macro now has 3 fixed parameters and one variadic parameter The first is the name of the exported function, the rest of the parameters are used to format a functionpointer in the jumptable, the EXPORT_FUNC macros are expanded three times, 1. to declare the members of the struct 2. to initialize the structmember pointers 3. to call the functions in stubs.c Signed-off-by: Martin Dorwig <dorwig@tetronik.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (resending to the list since my tweaks are not quite trivial)

2013-12-12ARM: fix the standalone programsJeroen Hofstee1-2/+2
The standalone programs do not use the api calls, but rely directly on u-boot variable gd->jt for the jump table. Commit fe1378a - "ARM: use r9 for gd" changed the register holding the address of gd, but the assembly code in the standalone examples was not updated accordingly. This broke the programs on ARM relying on the jumptable in the v2013.10 release. This patch unbricks them by using the correct register.

2010-07-04Make 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) { ...

2009-09-02Blackfin: change global data register from P5 to P3Robin Getz1-2/+2
Since the Blackfin ABI favors higher scratch registers by default, use the last scratch register (P3) for global data rather than the first (P5). This allows the compiler's register allocator to use higher number scratch P registers, which in turn better matches the Blackfin instruction set, which reduces the size of U-Boot by more than 1024 bytes...
