* Refactor flash moduleRandall Spangler2012-07-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a significant rewrite of the flash module, since it turns out that much less of the flash logic is actually common between stm32 and lm4.

* Add console functionalityRandall Spangler2012-07-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keys I keep hitting should work like I expect them to. Home or Ctrl+A = move to beginning of line End or Ctrl+E = move to end of line Del = delete-right Ctrl+K = delete to end of line Ctrl+L = clear screen and reprint current line Ctrl+N = next command Ctrl+P = previous command Also, improve filtering of escape sequences and non-printable characters, so hitting unsupported keys or control codes doesn't mess up the current line of input. BUG=chrome-os-partner:11666 TEST=manual type 'fhelpbar' home -> cursor moves to beginning of line Ctrl+E -> cursor moves to end of line Ctrl+A -> cursor moves to beginning of line (of course, if you're using Minicom, you'll need to type Ctrl+A A, since Minicom uses Ctrl+A as its control key) del -> 'helpbar' end -> cursor moves to end of line left-arrow 3 times -> cursor moves under 'b' Ctrl+L -> screen clears, cursor still under 'b' Ctrl+K -> 'help' Ctrl+Y Page-Up Page-Down -> nothing printed enter -> prints known commands (output of 'help' command) Ctrl+P -> 'help' Ctrl+N -> empty command line Change-Id: Id893c93b26db8f3deed6ea8be5aab88a3daaead4 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/28143
* Make ASSERT() report assertion failuresSimon Glass2012-06-221-1/+10
| | | | | | | | | | | | | | | | Rather than just reset the board, report assertion failures to aid debugging. To enable this, use CONFIG_ASSERT_HELP. BUG=chrome-os-partner:10149 TEST=manual Enable the option for snow, add a failing ASSERT() to the rw command and see the a nice message is printed now.

* Allow console commands abbreviationVadim Bendebury2012-05-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EC console input handling code is being enhanced to accept abbreviated command names. If the abbreviation is unique, the appropriate command is used, if the abbreviation is ambiguous, the command is handled as nonexistent. The error message is being modified to mention that the command either does not exist or is ambiguous. This change also makes it impossible to have command names matching the beginning of other command names. Two such cases are being fixed (`ch' renamed to `chan' and `thermal' renamed to 'thermalconf'). BUG=none TEST=manual . program the new EC image. Try entering at the console: > h Command 'h' either not found or ambiguous. Command returned error 1 > he Known commands: adc autofan battery ch charger ... > help Known commands: adc autofan battery ch charger ...

Reflash the EC and try it, and it should verify and reboot into RW A. Additional tests (setting USE_RO_NORMAL, poking random values into VBLOCK_A or FW_MAIN_A to force RW B to run, etc.) are left as an exercise for the reader. I've done them and they work, though.

* Export more battery information in LPC mapDuncan Laurie2012-04-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This data is used to populate the _BIF/_BIX packages in ACPI but it currently needs an EC command to retrieve that isn't easy to query in ACPI since it isn't using standard EC RAM. 1) Export these additional fields in init() state: - Design Capacity of Full - Design Voltage - Last Full Charge Capacity - Cycle Count - Manufacturer String - Model String - Serial Number String 2) Fix an issue where battery current was not reported when the battery was charging. 3) Remove the command interface so there is no duplication. BUG=chrome-os-partner:7734 TEST=using (not yet published) coreboot to read battery status via ACPI and verify that battery removal/insertion events are properly handled.
