* Clean up and document keyboard config optionsRandall Spangler2013-07-231-1/+2
| | | | | | | | | | | | | No functional changes, just renaming config options.

* do not store the keyboard state on the stackVincent Palatin2013-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | As our stack for the keyboard scanning task might be small (256 bytes on STM32), we store the full keyboard state in a global instead of the stack to avoid consuming 16 bytes there. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BRANCH=none BUG=chrome-os-partner:19389 TEST=run on Spring with CONFIG_OVERFLOW_DETECT and see that the KEYSCAN task is now consuming 248 bytes of stack instead of 264.

* Split lid switch code out of switch.c to its own fileRandall Spangler2013-04-021-3/+3
| | | | | | | | | | | | | This will allow ARM code to use the same lid switch code (in a subsequent CL).

* Add parse_bool() to centralize parsing boolean optionsRandall Spangler2013-03-291-12/+6
| | | | | | | | | | | | | | | | | | | | | | This way debug commands which previously took only yes/no or on/off or enable/disable can take any of those options.

* Merge lm4 and stm32 implementations of keyboard_scanRandall Spangler2013-03-291-71/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scanning is now performed identically on all platforms. keyboard_scan talks to chip-specific keyboard_raw on the bottom end, and 8042 or mkbp keyboard protocol on the top end. 8042 can now take advantage of CONFIG_KEYBOARD_TEST to simulate scan results. BUG=chrome-os-partner:18360 BRANCH=none TEST=compile all boards; test keyboard on spring and link 1) Type on keyboard. Should produce keystrokes. 2) At EC console: kbpress 3 7 1 kbpress 3 7 0 Should produce 'r' keystroke(s); key repeat should kick in if you wait a while between the commands. 3) Hold power button while typing. Should not produce keystrokes. 4) Reboot with power+refresh+esc. Should go to recovery mode. 5) While the system is up, alt+volup+R should reboot the AP.

* Move files in preparation for merging keyboard_scan modulesRandall Spangler2013-03-271-0/+502
This is part one of a series to merge the keyboard scan interface to be common across all platforms. This change just moves and renames files and APIs and removes some read code, and sets up protocol-specific CONFIG options. It makes the next CL which actually merges keyboard scanning easier to parse.
