* common, env: Fix support for environment in i2c eepromMatthias Fuchs2014-03-28-2/+7
| | | | | | | | When using CONFIG_SYS_I2C i2c needs to be initialized by i2c_init_all(). This is done in some places but not in eeprom_init(). Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu>
* cmd_eeprom: bug fix for i2c read/writeKuo-Jung Su2013-12-05-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The local pointer of address (i.e., addr) only gets referenced under SPI mode, and it won't be appropriate to pass only 1-byte addr[1] to i2c_read/i2c_write while CONFIG_SYS_I2C_EEPROM_ADDR_LEN > 1. 1. In U-boot's I2C model, the address would be re-assembled to a byte string in MSB order inside I2C controller drivers. 2. The 'CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW' option which could be found at soft_i2c.c is always turned on in cmd_eeprom.c, the addr[0] always contains the device address with overflowed MSB address bits.

* cmd_eeprom: fix i2c_{read|write} usage if env is in I2C EEPROMAlexey Brodkin2013-11-13-2/+2
| | | | | | | | | | | | | | | Data "offset" is not used directly in case of I2C EEPROM. Istead it is split into "block number" and "offset within mentioned block". Which are "addr[0]" and "addr[1]" respectively.

* Convert cmd_usage() calls in common to use a return valueSimon Glass2012-03-06-1/+1
| | | | | | | | | Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly. I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-2/+1
| | | | | | | | | | | | | | | | Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* cmd_eeprom: I2C updatesHeiko Schocher2010-01-18-6/+8
| | | | | | | | | | | | | - CONFIG_ENV_EEPROM_IS_ON_I2C define this, if you have I2C and SPI activated, and your EEPROM, which holds the environment, is on the I2C bus. - CONFIG_I2C_ENV_EEPROM_BUS if you have an Environment on an EEPROM reached over I2C muxes, you can now define, how to reach this EEPROM.

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