Standalone Apps: Standalone apps should need only exports.h.

2011-12-06T19:52:35+00:00

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

Constify getenv(), setenv() and hash code functions

2011-07-29T23:37:44+00:00

This is needed to get rid of build warnings like

main.c:311: warning: passing argument 2 of 'setenv' discards qualifiers from pointer target type

which result from commit 09c2e90 "unify version_string".

as checkpatch proposes to use strict_strtoul instead of
simple_strtoul, introduce it.

do_reset: unify duplicate prototypes

2010-11-28T20:47:24+00:00

The duplication of the do_reset prototype has gotten out of hand,
and they're not all in sync.  Unify them all in command.h.

Remove support for CONFIG_HAS_UID and "forceenv" command

2010-09-19T17:29:47+00:00

This (undocumented) concept was only in use for the MVSMR and
davinci_schmoogie Sergey Kubushyn  boards.
Drop it for now.  If really needed, it should be reimplemented
later in the context of the new environment command set.

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

2010-07-04T21:55:42+00:00

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) {
			...

Make *printf() return "int" instead of "void"

2010-07-04T21:51:49+00:00

Change the return type of the *printf() functions to the standard
"int"; no changes are needed but returning the already available
length count.

This will save a few additional strlen() calls later...

Generic udelay() with watchdog support

2009-12-05T00:08:53+00:00

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

ppc: Remove reloc_off field from global_data structure

2009-10-03T08:17:57+00:00

Now that proper relocation is supported, the reloc_off field is no longer
necessary.

Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot.

We therefore increment XF_VERSION to 6
