Revert "tacoma: Remove CP0 reset" This reverts commit 5ef58e42bd2c27605cd952bf590b2879759425d8. There is a unknown issue with Tacoma hardware in which the CP0 reset needs to happen within the power_control.exe. The theory is it is timing related (i.e. the CP0 reset needs to occur extremely close to the power being turned on). Given that Tacoma is a development system, time has not been allotted to getting to the bottom of this. It works fine on some systems, but fails catastrophically on others with an assortment of power fault errors. Due to this issue, we can not utilize the new kernel mechanism for controlling CP0 on Tacomas. Change-Id: I793ed0259426e6b42021fb92ca869fd2b6e15ace
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
