Commit7653942b10("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was used in linking scripts to allow fine placement of embedded environment sections. This implies that GCC randomly places objects from env/embedded.o and environment is not guaranteed to be located at the correct address: 04003df8 g F .text 00000038 mii_init 04004000 g O .text 00000004 env_size 04004004 g O .text 00002000 environment 04006004 g F .text 00000040 .hidden __lshrdi3 This patch restores this capability by allocating each object marked with __UBOOT_ENV_SECTION__ into a different section. Hence 'environment' will be alone in .text.environment, allowing a fine placement in u-boot.lds with: . = DEFINED(env_offset) ? env_offset : .; env/embedded.o (.text.environment) Fixes:7653942b10("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
