* eeprom: merge cmdline parsing of eeprom commandsNikita Kiryanov2016-05-20-64/+53
| | | | | | | | | | | | | | Merge the parsing of layout aware and layout unaware eeprom commands into one parsing function. With this change, layout aware commands now follow the eeprom read and eeprom write conventions of making i2c bus and i2c address parameters optional.

* eeprom: use eeprom_execute_command for all eeprom functionsNikita Kiryanov2016-05-20-21/+40
| | | | | | | | | | | | | | | | Update eeprom_execute_command() and related code to accommodate both layout aware and layout unaware functions. No functional changes.

* eeprom: refactor i2c bus and devaddr parsingNikita Kiryanov2016-05-20-26/+53
| | | | | | | | | | | | | | | Introduce parse_i2c_bus_addr() to generalize the parsing of i2c bus number and i2c device address. This is done in preparation for merging layout aware and layout unaware command parsing into one function. No functional changes.

* cmd: eeprom: add support for layout aware commandsNikita Kiryanov2016-05-20-1/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the (optional) eeprom print and eeprom update commands. These commands are eeprom layout aware: * The eeprom print command prints the contents of the eeprom in a human readable way (eeprom layout fields, and data formatted to be fit for human consumption). * The eeprom update command allows user to update eeprom fields by specifying the field name, and providing the new data in a human readable format (same format as displayed by the eeprom print command). * Both commands can either auto detect the layout, or be told which layout to use. New CONFIG options: CONFIG_CMD_EEPROM_LAYOUT - enables commands. CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported Feature API: __weak int parse_layout_version(char *str) - override to provide your own layout name parsing __weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version); - override to setup the layout metadata based on the version __weak int eeprom_layout_detect(unsigned char *data) - override to provide your own algorithm for detecting layout version eeprom_field.c - contains various printing and updating functions for common types of eeprom fields. Can be used for defining custom layouts.

* cmd: eeprom: add bus switching support for all i2c driversNikita Kiryanov2016-05-20-1/+1
| | | | | | | | | | | | | The i2c_init function is always provided when CONFIG_SYS_I2C is defined. No need to limit ourselves to just one supported I2C driver (soft_i2c). Update the #ifdef conditions to support bus switching for all I2C drivers.

* i2c/eeprom: Always define I2C_RXTX_LENMario Six2016-05-03-0/+4
| | | | | | | | | | | I2C_RXTX_LEN from include/i2c.h is not defined if CONFIG_DM_I2C is enabled. This leads to a compilation error on boards that enable both CONFIG_CMD_EEPROM and CONFIG_DM_I2C. To avoid this, we define I2C_RXTX_LEN in cmd/eeprom.c if it is not already defined. Signed-off-by: Mario Six <mario.six@gdsys.cc>
* Remove the cmd_ prefix from command filesSimon Glass2016-01-25-0/+265
Now that they are in their own directory, we can remove this prefix. This makes it easier to find a file since the prefix does not get in the way.
