cmd_mem.c: Fix warning when CONFIG_CMD_MEMTEST is not set

2013-03-12T16:43:31+00:00

mem_test_quick and mem_test_alt functions are only called by
do_mem_mtest, so move them under the #ifdef

Feature Removal: disable "mtest" command by default

2013-03-11T19:26:59+00:00

The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses.  If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users?  As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.

As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h;  we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.

sandbox: Update mtest to fix crashes

2013-03-01T03:49:11+00:00

Use map_sysmem() in the memory tester so that it works as expected on
sandbox.

Move CONFIG_SYS_MEMTEST_SCRATCH #ifdef to top of file

2013-03-01T03:09:24+00:00

This config effectively has a default value of 0, so add this setting
at the top of the code to remove an #ifdef in the C function.

Roll crc32 into hash infrastructure

2013-03-01T03:09:23+00:00

Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.

Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).

Reduce casting in mtest

2013-03-01T03:09:22+00:00

Use a ulong for the command arguments, and only cast to an address when
needed. This fixes warnings in sandbox where pointers are typically 64 bits
long.

Bring mtest putc() into common code

2013-03-01T03:09:22+00:00

If we get a Ctrl-C abort, we always print a newline. Move this repeated
code out of the functions and into a single place in the caller.

Fix mtest indenting

2013-03-01T03:09:22+00:00

Some of the inner loops are not indented correctly. Fix this.

Use common mtest iteration counting

2013-03-01T03:09:22+00:00

The iteration code is the same for each version of the memory test, so
pull it out into the common function.

Split out the memory tests into separate functions

2013-03-01T03:09:22+00:00

Half of the code is currently hidden behind an #ifdef. Move the two
memory tests into their own functions and use the compiler to eliminate
the unused code.
