From 6ac226d915ade86216d77316c77f824a07dd0e1c Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 15 Jun 2016 17:13:20 -0700 Subject: intel/apollolake: Enable SPI properly in bootblock and ramstage Bootblock: - Temporary BAR needs to be assigned for SPI device until PCI enumeration is done by ramstage which allocates a new BAR. - Call spi_init to allow bootblock/verstage to write/erase on flash. Ramstage: - spi_init needs to run in ramstage to allow write protect to be disabled for eventlog and NVRAM updates. This needs to be done pretty early so that any init calls(e.g. mainboard_ec_init) writing to flash work properly. Verified with this change that there are no more flash write/erase errors for ELOG/NVRAM.
