New patch to review for coreboot: libpayload: Replace majority of timer drivers with a generic one
Martin Roth (martinroth@google.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/15035 -gerrit commit 1b2fc37c41ddd2cbedae911b5e0eb9d7d7b8ab23 Author: Julius Werner <jwerner@chromium.org> Date: Mon May 16 15:39:12 2016 -0700 libpayload: Replace majority of timer drivers with a generic one Currently every non-x86 platform supported by libpayload needs to provide its own timer driver. Most of the ones we have accumulated there look almost identical: For the frequency, return a preset constant. For the value, read a 32-bit register, possibly read another 32-bit register and shift+OR it with the previous one, then return that. Let's replace this with a single .c file that can easily handle all of those cases. Menuconfig convenience can still be maintained by providing several presets that select different defaults for the driver's configuration options (register address(es) and frequency). Removes an "enabled" check from Samsung MCT driver since coreboot always unconditionally enables that timer anyway.
