2014-02-21Fix memory commands for 64-bit platformsYork Sun
For aarch64, unsigned long is 64-bit data. Memory commands should be fixed with u32 for 32-bit address access. To be clear, ushort is replace with u16, u_char is replaced with u8. Signed-off-by: York Sun <yorksun@freescale.com> Acked-by: Wolfgang Denk <wd@denx.de>
2014-02-21fix address of error message in mtest commandDavid Feng
This patch deal with error message of mtest command. When test failed, the mtest command will output error information that include memory address and value. But the address field is not correct or misleading. Signed-off-by: David Feng <fenghua@phytium.com.cn>

2013-06-26Fix missing return in do_mem_loop()Simon Glass
For some reason this does not normally cause a compiler warning, but the code seems to be incorrect. Add the missing return. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-05-24cmd_mem: fix cp commandMasahiro Yamada
The "cp" command has not worked since commit 0628ab8ec59834f98ede267edd21ddb8ba0bb57b, because of the following lines, which set the destination and the source to the same address. buf = map_sysmem(addr, bytes); src = map_sysmem(addr, bytes); Tested-by: Tom Rini <trini@ti.com> Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2013-03-12cmd_mem.c: Fix warning when CONFIG_CMD_MEMTEST is not setTom Rini
mem_test_quick and mem_test_alt functions are only called by do_mem_mtest, so move them under the #ifdef Signed-off-by: Tom Rini <trini@ti.com>
2013-03-11Feature Removal: disable "mtest" command by defaultWolfgang Denk
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.

2013-02-28sandbox: Update mtest to fix crashesSimon Glass
Use map_sysmem() in the memory tester so that it works as expected on sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-28Move CONFIG_SYS_MEMTEST_SCRATCH #ifdef to top of fileSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-28Roll crc32 into hash infrastructureSimon Glass
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). Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-28Reduce casting in mtestSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-28Bring mtest putc() into common codeSimon Glass

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. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-01-10Add option to display customised memory informationSimon Glass
Some boards want to report more than just memory size. For example, it might be useful to display the memory type (DDR2, DDR3) or manufacturer. Add a weak function to support this requirement, accessed through a new 'meminfo' command. Any example of the DRAM: output is below, just for illustration: SMDK5250 # meminfo DRAM: 2 GiB Elpida DDR3 @ 800MHz Signed-off-by: Simon Glass <sjg@chromium.org>

2011-02-15unzip: return uncompressed size in `filesize', and print it.Wolfgang Denk
The unzip command did not provide a way for the caller to get any information about the uncompressed size. To make it better usable in scripts, we now store the uncompressed size in the `filesize' variable, like we do when for example loading a file over the network or when reading it from a file system. Following that analogy, it is only consequent to also print the size. Signed-off-by: Wolfgang Denk <wd@denx.de>

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...

2009-12-21move prototypes for gunzip() and zunzip() to common.hWolfgang Wegner
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 <w.wegner@astro-kom.de>
2009-10-18mem_mtest: fix error reporting, allow escape with ^CPaul Gortmaker
The basic memtest function tries to watch for ^C after each pattern pass as an escape mechanism, but if things are horribly wrong, we'll be stuck in an inner loop flooding the console with error messages and never check for ^C. To make matters worse, if the user waits for all the error messages to complete, we then incorrectly report the test passed without errors. Adding a check for ^C after any error is printed will give the end user an escape mechanism from a console flood without slowing down the overall test speed on a slow processor. Also, the more extensive memtest quit after just a single error, which is inconsistent with the normal memtest, and not useful if if you are doing dynamic environmental impact testing, such as heating/cooling etc. Both tests now track the error count and report it properly at test completion.

2009-06-12General help message cleanupWolfgang Denk
Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
