From b763b37411f82c8df091cc4f15925db9daa5ce2e Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Thu, 26 Sep 2019 12:33:25 +0800 Subject: mb/google/kukui: Extend FMAP to 8MB layout The SPI flash component requirement for Kukui family is 8M so we should update FMAP for that: - Add more comments for alignment and size recommendation. - Enlarge RO to 4M, and RW_SECTION_{A,B} both ~1.5M. - BOOTBLOCK: 32K->128K, aligned with other ARM boards. - Preserve RW_DDR_TRAINING for new calibration. - Reorder the sections for better alignment. - RW_MISC to contain RW sections that should be merged when creating AU image.
