* HBBL LPC Error CheckingBill Hoffa2019-02-081-1/+4
| | | | | | | | | | | | | | | | | | - 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.

* lpc: Add support for large read/write opsBill Hoffa2017-05-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | On P9 the LPC is memory mapped. The LPC FW space used to map the flash is generally acccessed to read or write rather large amounts of data. Its inefficient to go through the whole dispatch and locking for every single 4 bytes read or written. This adds the ability to request reads or writes of larger quantities for FW space. The implementation uses memcpy whose current implementation in HostBoot will perform well for 8 bytes aligned accesses, but will downgrate to bytes accesses otherwise.

* FFS Support for Bootloadercrgeddes2016-03-031-0/+48
This commit moves functionality out of pnor_common.C and puts it in a new file pnor_utils.C this file will be shared with bootloader and hostboot code. Quite a few files were pulled apart in order to make includes easier across modules. These are lpc_const.H and pnor_const.H. bl_pnorAccess leverages the new pnor_utils.C file that will help the bootloader parse pnor TOC Change-Id: I740f6f8a707760756a261535e62e2d0a849324f8 RTC:134064 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/696 Tested-by: Jenkins Server Reviewed-by: Martin Gloff <mgloff@us.ibm.com> Reviewed-by: Daniel M.
