linux: Disable GEN_RTC

With CONFIG_GEN_RTC=y set in the defconfig the generic RTC driver will
take precedence over the proper OPAL RTC driver. To the user this
results in errors like:

$ hwclock -r
Sun Dec 31 00:00:00 1899  0.000000 seconds
$ hwclock -w
hwclock: RTC_SET_TIME: Invalid argument

Remove CONFIG_GEN_RTC to allow the OPAL RTC driver to be properly
initialised.

OpenPower Firmware Build Environment

The OpenPower firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

Development

Issues, Milestones, pull requests and code hosting is on github: https://github.com/open-power/op-build

Mailing list: openpower-firmware@lists.ozlabs.org

Building an image

git clone --recursive git@github.com:open-power/op-build.git
cd op-build
. op-build-env
op-build palmetto_defconfig && op-build

This will build an image for a Palmetto system. There exists default configurations for other platforms in openpower/configs/ such as Habanero and Firestone.
