the following patch was just integrated into master: commit dd6c4ec1ed64f3d9803cca6eb53fa5049cacdd09 Author: Shawn Nematbakhsh shawnn@chromium.org Date: Fri Aug 23 14:12:24 2013 -0700
libpayload: Remove unnecessary keyboard mode setting code
keyboard_init attempts to read the existing mode register, set the 'XLATE' bit, and write it back. The implementation is buggy because the keyboard may be active at the time we read the mode, and we can misinterpret scancode data as the reply to our command. It leads to problems where the KB gets disabled in firmware.
In fact, setting the 'XLATE' bit is completely unnecessary, even if we desire QEMU keyboard support. We already set this bit when we initialize the keyboard in pc_keyboard_init. Basically, this code does nothing (or worse), so just remove it.
