rk3399 fails to build: region PMUSRAM overflowed

[vagrantc]

Working on packaging arm-trusted-firmware in Debian.

Building arm-trusted-firmware from git commit cabe0a31801e99e7abb84d2114ded6bb56f3c71e or v2.0, rk3399 fails to build with a recent Debian toolchain (gcc 8.2.0, binutils 3.31.1):

Must remake target 'build/rk3399/debug/bl31/bl31.elf'.
LD build/rk3399/debug/bl31/bl31.elf
aarch64-linux-gnu-ld.bfd: build/rk3399/debug/bl31/bl31.elf section .pmusram' will not fit in region PMUSRAM'
aarch64-linux-gnu-ld.bfd: region `PMUSRAM' overflowed by 3928 bytes
make[2]: *** [Makefile:722: build/rk3399/debug/bl31/bl31.elf] Error 1
make[2]: Leaving directory '/<>'

Full build log available at:

Works fine building with the older toolchains (gcc 6, binutils 2.28) in Debian, but it's not possible to include arm-trusted-firmware in an older release; the newer toolchains are required to work for new uploads.

Thanks!

By the way, there is a video about the problem of fitting all the code that is needed to be placed in the PMUSRAM: https://youtu.be/UC35q4OJg3k?t=1350

However, "overflowed by 3928 bytes" looks like there is some problem with the new version of the linker, not like GCC has become that worse in 2 major versions. There were only ~4KB of code for each CPU type (M0 and A72/53) to begin with.

Agreed, this looks like a bug or serious regression, not just a natural change in code generation.

@rkchrome, can Rockchip people look into this?

It looks like @rkchrome is an old account and the correct one is @rockchip-linux.

Which version of the compilers are you using? I'm using the following compilers from here: https://developer.arm.com/open-source/gnu-toolchain/gnu-a/downloads

gcc-arm-8.2-2019.01-x86_64-arm-eabi
gcc-arm-8.2-2019.01-x86_64-aarch64-linux-gnu

And it seems to build correctly.

I am getting a similar error on a current archlinux system with

aarch64-linux-gnu-gcc (GCC) 11.2.0
aarch64-linux-gnu-ld GNU ld (GNU Binutils) 2.38
