Use the return value of cmd_usage instead of ignoring this and returning a 1. Signed-off-by: Thomas Weber <weber@corscience.de> Acked-by: Mike Frysinger <vapier@gentoo.org>
Guard strchr/strlen from being called with NULL pointer. This line is crashing when command "env" is called without subcommand. The cmd is NULL in this case because the calling function "do_env" decremented the argc without checking if there are still arguments available. Signed-off-by: Thomas Weber <weber@corscience.de>

Some boards use an embedded environment, where env_embedded.o has to be linked at a special position in the U-Boot image; to make this possible, we do not include it into libcommon.o for such boards.

Since we set #define MORECORE_CLEARS 1, the code assumes 'sbrk' always
returns zero'd out memory. However since its possible that free()
returns memory back to sbrk() via malloc_trim we could possible get
non-zero'd memory from sbrk(). This is a problem for when code might
call calloc() and expect the memory to have been zero'd out.
There are two possible solutions to this problem.
1. change #define MORECORE_CLEARS 0
2. memset to zero memory returned to sbrk.
We go with the second since the sbrk being called to free up memory
should be pretty rare.
The following code problems an example test to show the issue. This
test code was inserted right after the call to mem_malloc_init().
...
u8 *p2;
int i;
printf("MALLOC TEST\n");
p1 = malloc(135176);
printf("P1 = %p\n", p1);
memset(p1, 0xab, 135176);
free(p1);
p2 = calloc(4097, 1);
printf("P2 = %p %p\n", p2, p2 + 4097);
for (i = 0; i < 4097; i++) {
if (p2[i] != 0)
printf("miscompare at byte %d got %x\n", i, p2[i]);
free(p2);
printf("END MALLOC TEST\n\n");

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
This change does the following:
- Removes the printing of the PCI interrupt line value. This is
normally set to 0 by U-Boot on bootup and is rarely used during
everyday operation.
- Prints out the PCI function number of a device. Previously a device
with multiple functions would be printed identically 2 times, which is
generally confusing. For example, on an Intel 2 port gigabit Ethernet
card the following was displayed:
...
04 01 8086 1010 0200 00
04 01 8086 1010 0200 00
...
- Prints a text description of each device's PCI class instead of the
raw PCI class code. The textual description makes it much easier to
determine what devices are installed on a PCI bus.
- Changes the general formatting of the PCI device output.
