Mark bootloader RCs for FSP export

2019-11-14T16:16:02+00:00

We missed adding the magic flag to the HBBL RCs that FSP needs to process.

Added more error reporting to HWSV when PNOR fails, removed superfluous code

2019-05-07T13:51:08+00:00

- Replaced the terminate (terminateExecuteTI) raw calls with bl_terminate. Returning descriptive RC codes with bl_terminate call. - Module ID MOD_PNORACC_FINDTOC(=0x08) was added to hbblModuleId enums. - Return codes RC_LPC_ERR(HBBL_COMP_ID | 0x10) and RC_TOC_NOT_FOUND_ERR(HBBL_COMP_ID | 0x11) added to hbblReasonCode enums. - Freed up space in bootoloader: - Removed unnecessary calls to the method PNOR::checkForNullBuffer, because the call is always guaranteed to return with no error. - Once the calls to PNOR::checkForNullBuffer were dropped, the method PNOR::checkForNullBuffer is no longer necessary - removed it from production code. - The unit tests relied heavily on the call to PNOR::checkForNullBuffer, was not sure if the call could be removed from the unit tests, so relocated the PNOR::checkForNullBuffer method to the unit tests, out of production code.

This reverts commit ee1cd5b0adfaf133abe846ccbaebe48d7dbded0f. We overran our size constraint in the bootloader. Change-Id: Ib579b5971e5f03131a0b6580cd698e7f725dd383 Reviewed-on: http://rchgit01.rchland.ibm.com/gerrit1/72401 Tested-by: Jenkins Server Reviewed-by: Daniel M. Crowell

HBBL LPC Error Checking

2019-02-08T21:42:06+00:00

- To avoid IPL delays, the LPC status register should be checked prior to loading the entire PNOR image (done via LPC). If an error condition occurs, HBBL should fail out.

Support HB running in SMF

2018-09-24T17:17:16+00:00

Support SMF for P9N/P9C. Lots of minor tweaks to make this work, but the biggest is to run userspace in problem state This is needed because for SMF Hostboot will need to run in S=1, HV=0,PR=1 (and kernel in S=1, HV=1, PR=0) This commit makes P9 HB userpsace run in HV=0 PR=1 and kernel in HV=1, PR=0.

Write Hostboot HRMOR into core scratch reg 1

2018-06-04T21:32:40+00:00

Hostboot code will write the current HRMOR value into core scratch reg 1 (scom=xx010A87, spr=0x08) at initial boot. This data is ORed into the memory size data that was already present. The bootloader code will do the same. Also updated the debug tools to key off of this data if it is available to avoid any HRMOR hardcoding. The purpose of this change is to provide a method for the FSP code to handle various memory remapping scenarios that are currently in plan without needing any explicit communication from Hostboot.

Secure Boot: Support Phyp debug flag in HDAT

2018-04-09T20:29:14+00:00

PHYP needs a way to know if SBE security backdoor is enabled for debug purposes. This change creates a flag in TPM instance data structure to indicate whether the backdoor is enabled. This flag is passed by SBE to the hb bootloader; also added the flag to indicate whether PCR is poisoned (default of 0). The population of this flag will be implemented on Fleetwood.

- Removing the magic number checks that would block sb functionality if things didn't appear secure - Remove Best Effort Policy and all of its related code - Remove the legacy PCR extension - Remove the non-secure header preservation path. - Always load HB base image header from the bl to hb data path vs settings unsecurely out of pnor Change-Id: Ie638384ac50ed47850985c959ea7a32e5757d64e RTC: 178520 RTC: 155374 RTC: 173489 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/49925 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Reviewed-by: Nicholas E.
