* cmd_i2c: Provide option for bulk 'i2c write' in one transactionLubomir Popov2015-02-19-9/+36
| | | | | | | | | | | | | | | | | | | I2C chips do exist that require a write of some multi-byte data to occur in a single bus transaction (aka atomic transfer), otherwise either the write does not come into effect at all, or normal operation of internal circuitry cannot be guaranteed. The current implementation of the 'i2c write' command (transfer of multiple bytes from a memory buffer) in fact performs a separate transaction for each byte to be written and thus cannot support such types of I2C slave devices. This patch provides an alternative by allowing 'i2c write' to execute the write transfer of the given number of bytes in a single bus transaction if the '-s' option is specified as a final command argument. Else the current re-addressing method is used. Signed-off-by: Lubomir Popov <l-popov@ti.com> hs: adapt to CONFIG_DM_I2C
* cmd_i2c: quit I2C commands immediately on errorMasahiro Yamada2015-02-19-13/+13
| | | | | | | | | | | If the i2c driver returns an error status, error out immediately. Continuing the loop just results in printing error messages again and again.

* dm: i2c: Add a dm_ prefix to driver model bus speed functionsSimon Glass2015-02-12-2/+2
| | | | | | | | As with i2c_read() and i2c_write(), add a dm_ prefix to the driver model versions of these functions to avoid conflicts. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Heiko Schocher <hs@denx.de>
* dm: i2c: Provide an offset length parameter where neededSimon Glass2015-01-29-1/+1
| | | | | | | | | | Rather than assuming that the chip offset length is 1, allow it to be provided. This allows chips that don't use the default offset length to be used (at present they are only supported by the command line 'i2c' command which sets the offset length explicitly).

* dm: i2c: Rename driver model I2C functions to permit compatibilitySimon Glass2015-01-29-12/+16
| | | | | | | | | | | Add a dm_ prefix to driver model I2C functions so that we can keep the old ones around. This is a little unfortunate, but on reflection it is too difficult to change the API. We can undo this rename when most boards and drivers are converted to use driver model for I2C. Signed-off-by: Simon Glass <sjg@chromium.org>
* cmd_i2c: change variable type for 10bit addressing supportMasahiro Yamada2015-01-29-11/+11

* dm: i2c: Implement driver model support in the i2c commandSimon Glass2014-12-11-53/+323
| | | | | | | | | | | The concept of a 'current bus' is now implemented in the command line rather than in the uclass. Also the address length does not need to be specified with each command - really we should consider dropping this from most commands but it works OK for now.

* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-1/+1
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* General help message cleanupWolfgang Denk2009-06-12-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
