Rename getenv_r() into getenv_f()

2010-08-03T22:45:36Z

While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk Acked-by: Detlev Zundel

cmd_usage(): simplify return code handling

2010-07-24T18:43:57Z

Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too. Signed-off-by: Wolfgang Denk

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) { ...

Move arch/ppc to arch/powerpc

2010-04-21T21:42:38Z

As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

Rename lib_generic/ to lib/

2010-04-13T07:13:04Z

Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser

Move lib_$ARCH directories to arch/$ARCH/lib

2010-04-13T07:13:03Z

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

move prototypes for gunzip() and zunzip() to common.h

2009-12-21T20:39:59Z

Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus repeated in every file using it. This patch moves the prototypes to common.h and removes all prototypes distributed anywhere else. Signed-off-by: Wolfgang Wegner

POST: Remove duplicated post_hotkey_pressed() functions

2009-12-07T21:44:31Z

This patch introduces a weak default function for post_hotkey_pressed(), returning 0, for boards without hotkey support. The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese

Add a unified s3c24x0 header file

2009-11-27T22:26:13Z

This patch adds a unified s3c24x0 cpu header file that selects the header file for the specific s3c24x0 cpu from the SOC and CPU configs defined in board config file. This removes the current chain of s3c24-type #ifdef's from the s3c24x0 code. Signed-off-by: Kevin Morfitt Signed-off-by: Minkyu Kang

Clean-up of s3c24x0 header files

2009-11-27T22:26:13Z

Cleans up the s3c24x0 header files: s4c24x0.h: removes the use of 'volatile' from the S3C24X0_REG8, S3C24X0_REG16 and S3C24X0_REG32 register typedef's. Registers are always accessed using the IO accessor functions which cast the register address as 'volatile' anyway so it isn't required here. s3c2400.h and s3c2410.h: insert a blank line between the static inline functions Signed-off-by: Kevin Morfitt
