tacoma: Remove CP0 reset This is wired as to do nothing on normal Witherspoons, so the code to do so has questionable utility. On Tacoma systems, the Witherspoon motherboard is reworked to allow the BMC to control the reset. The control is provided as part of the FSI driver in the kernel, so it should be removed from the userspace power control tool. Fixing this should resolve this message when doing poweron: power_control.exe[250]: ERROR PowerControl: GPIO open error (gpio=BMC_CP0_RESET_N,rc=2) The GPIO device can't be opened as the kernel has control of it.

This layer provides support for the BMC firmware on IBM POWER systems server products.
This layer depends on: URI: git://git.openembedded.org/openembedded-core layers: meta branch: master revision: HEAD URI: https://github.com/openbmc/meta-phosphor branch: master revision: HEAD URI: https://github.com/openbmc/meta-openpower branch: master revision: HEAD URI: https://github.com/openbmc/meta-aspeed branch: master revision: HEAD
The following systems are supported.
Witherspoon, or AC922, is an IBM POWER9 two-socket, 2U Accelerated Compute Server with up to 6 NVIDIA Tesla GPUs. More information can be found here.
In addition to witherspoon, this layer contains additional machine configurations such as swift. The default machine target is witherspoon, so in order to build a different configuration, or to build witherspoon after building a different one, set the MACHINE environment to the desired configuration name (see the conf/machine/ subdirectory for available options):
export MACHINE=machine_configuration_name
Then build:
bitbake obmc-phosphor-image
Example:
export MACHINE=swift bitbake obmc-phosphor-image bitbake phosphor-logging export MACHINE=witherspoon bitbake obmc-phosphor-image
