Incorrect section attributes with ALLOW_RO_XLAT_TABLES=1

by Masahiro Yamada

Hi. If I build TF-A with ALLOW_RO_XLAT_TABLES=1, the base xlat table goes into .rodata section instead of .bss section. Then, I see a warning like: /tmp/ccswitLr.s: Assembler messages: /tmp/ccswitLr.s:297: Warning: setting incorrect section attributes for .rodata Is this a know issue? [Reproduce Command] make PLAT=fvp CROSS_COMPILE=aarch64-linux-gnu- ALLOW_RO_XLAT_TABLES=1 The full build log is below: masahiro@pug:~/ref/trusted-firmware-a$ make PLAT=fvp
