Fix build problems caused by "_end" -> "__bss_end__" rename

2011-03-31T06:54:35Z

Commit 44c6e65 "rename _end to __bss_end__ broke building of a large number of systems (at least all PowerPC?): libstubs.o: In function `app_startup': examples/standalone/stubs.c:197: undefined reference to `__bss_end__' The rename should not be done for the files in the examples/standalone/ directory, as these are not using the code from start.S, but do their own BSS clearing, and either use their own linker scripts or the ones provided by the compilers.

rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

Make sure that argv[] argument pointers are not modified.

2010-07-04T21:55:42Z

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) { ...

The nios-32 arch is obsolete and broken. So it is removed. Signed-off-by: Thomas Chou

nios2: fix r15 issue for gcc4

2010-05-28T14:56:03Z

The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

Blackfin: change global data register from P5 to P3

2009-09-02T09:14:02Z

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...

Move examples/ to examples/standalone

The current files in examples are all standalone application examples, so put them in their own subdirectory for organizational purposes Signed-off-by: Peter Tyser
