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.

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.
