Compile Hostboot with -Os

2019-10-03T15:55:14+00:00

Hostboot currently spends a significant percentage of time loading data from PNOR across a relatively slow LPC bus. This commit enables compilation of Hostboot with -Os, optimized for space to reduce the amount of data required to be transferred across the LPC bus Rough measurements show a ~30% size reduction of the hostboot image and a ~10% reduction (improvement) in boot time Change-Id: Ib73863019595a24cc7d10e924bc5c92cd64af1ed Reviewed-on: http://rchgit01.rchland.ibm.com/gerrit1/84436 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Tested-by: FSP CI Jenkins Reviewed-by: William G Hoffa

Add wrapper to exp_getidec HWP so we can call it in platform code

2019-09-20T21:14:31+00:00

There has been a trend to create more HWPs that process raw data. This allows Hostboot and Cronus to share more code. The trick is that we generally want to call these HWPs inside traditionally hostboot-only code. This new fapiwrap directory will help encapsulate all of the calls to ekb code in one place. That way if we ever need to remove HWPs/EKB code it will be easier to stub out the calls. In the past we have contaminated a lot of Hostboot-only code with calls out to EKB code. This new new directory should help avoid this issue.

Test runtime scom support in Axone

Needed to disable i2c explorer command tests during runtime. Currently just support mmio operations for runtime.

Runtime scom support for OCMBs

2019-08-15T22:06:46+00:00

fapi2::getScom on OCMB targets eventually resolves to a mmio call at runtime. This commit registers a runtime version of mmioScomPerformOp to the IBSCOM device ops for OCMB targets. During runtime, hostboot will rely on the hypervisor (opal/phyp) to issue the inband commands to perform the operation on the desired OCMB.

This reverts commit cd1e5c91e4a15ca933c699553ece9b841825ac03. The previous change seems to be causing problems with thread local storage (TLS) access.

Somehow the axone test cases never got turned on. They all passed after enabling though.

OCMB MMIO error handling

2019-06-07T19:41:25+00:00

Added the following -Error checking and FRU isolation on explorer side -Cleaned up MMIO write error handling to read an MMIO error register -Fixed and enabled MMIO test cases -Moved parameter checking and channel checkstop checking into seperate functions. -Only check for channel checkstop for the channel that an OCMB is connected to. -Switch to using I2C on first MMIO failure.
