From 0d7046d70887f9276b33a45f003761e810eea648 Mon Sep 17 00:00:00 2001 From: Tom Hochstein Date: Wed, 30 Jun 2021 07:10:22 -0500 Subject: imx-atf: Remove -O2 from CFLAGS for 8MQ The i.MX 8M Quad has only 64 kB of OCRAM, and the following build break is observed: ``` | aarch64-poky-linux-ld.bfd: /opt/work/upstream/fsl-xwayland/tmp/work/cortexa53-crypto-mx8m-fsl-linux/imx-atf/2.4+gitAUTOINC+ec35fef92b-r0/git/build-optee/imx8mq/release/bl31/bl31.elf section `coherent_ram' will not fit in region `RAM' | aarch64-poky-linux-ld.bfd: BL31 image has exceeded its limit. | aarch64-poky-linux-ld.bfd: region `RAM' overflowed by 4096 bytes ``` Fix the break by disabling -O2 optimization.
