2019-06-06Revert "libpayload: Reset PS/2 keyboard"Nico Huber
Documentation is scarce on the matter, however the related coreboot code suggests that after the ACK, the keyboard also sends the result of the self test (passed/failed). It looks like this result is never consumed here, probably resulting in further confusion for later com- mands. Let's revert this for now (if it's not too late for the 4.10 release) and break things later again. IMHO, due to the fact that there are dozens of different keyboard controller and keyboard implementations and no accurate specification followed, such changes should be tested on a lot of hardware before merge. This reverts commit a99ed13e3397bc536012120aab8cadb827913863. This reverts commit 7ae606f57f0b3d450ae748141b0e2367041b27d3.

2019-06-04libpayload/i8042/keyboard: Fix return value check for keyboard_cmdFurquan Shaikh
CB:32951 ("libpayload: Reset PS/2 keyboard") added a call to reset keyboard and check the return value of keyboard_cmd() to compare against I8042_KBCMD_ACK. However, keyboard_cmd() already checks for ACK and returns 1 or 0 based on whether ACK is received. This change fixes the check introduced by CB:32951 to compare against 0 just like the other checks for keyboard_cmd(). Additionally, it adds error messages for all failed commands in keyboard_init() to make the prints consistent in case of failure. BUG=b:134366527 TEST=Verified that logs do not contain "ERROR: Keyboard reset failed" anymore.

2019-05-27libpayload: Reset PS/2 keyboardPaul Menzel
Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or GRUB pressing keys does not give the expected results. For example, pressing F1 gives the character 24 translated to scan code 6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU Q35. The problem is not reproducible using the payload directly, that means without SeaBIOS or GRUB. The problem seems to be, that those have already initialized the PS/2 controller and AT keyboard. Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to be reset. That seems to fix the issue, when the keyboard was initialized before. TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary payload. Run qemu-system-i386 -M q35 -L /dev/shm -bios build/coreboot.rom -serial stdio press 3 to select the coreinfo payload, and verify that the keys F1 and F2 are working. Same with coreinfo loaded from GRUB on the ASRock E350M1.

2019-05-13libpayload: classify all keyboardsMatt Delco
Depthcharge uses the keyboard type to help determine whether it can trust the keyboard for security-sensitive confirmations. Currently it trusts anything except usb, but now there's a need to distrust ec-based ps/2 keyboards that are associated with untrusted ECs. To help facilitate this, coreboot needs to report more details about non-usb keyboards, so this change replaces the current instances of unknown with enum values that distinguish uart and gpio from ec-based keyboards. BUG=b:129471321 BRANCH=None TEST=Local compile and flash to systems with trusted and non-trusted ECs. Confirmed that security confirmation can't be performed via keyboard on a system with an untrusted EC but can still be performed on a system with a trusted EC.

2019-03-02libpayload: keyboard: Add option to ignore failures during initDuncan Laurie
If keys are pressed at boot some keyboard controllers will not properly respond with an ACK to commands, which results in the keyboard_init function aborting before it adds the keyboard to the input device list. This same keyboard controller will manage to properly return keyboard data when keys are pressed later, so it is possible for it to be functional in the payload even if it does not respond properly to every command during initialization. In order to allow payloads to use the keyboard when this happens a new Kconfig option is added to ignore the keyboard ACK response and always add the keyboard to the input device list. This option is disabled by default and must be enabled by the specific boards that need it. BUG=b:126633269 TEST=boot on device with this controller and press keys during boot and see that the keyboard is still functional in the payload.
