ChangeLog entry is as follows:

*** gcc/ChangeLog ***

2017-07-14  Thomas Preud'homme  <thomas.preudho...@arm.com>

    * config/arm/arm-cpus.in (cortex-r52): Add new entry.
    (armv8-r): Set ARM Cortex-R52 as default CPU.
    * config/arm/arm-tables.opt: Regenerate.
    * config/arm/arm-tune.md: Regenerate.
    * config/arm/driver-arm.c (arm_cpu_table): Add entry for ARM
    Cortex-R52.
    * doc/invoke.texi: Mention -mtune=cortex-r52 and availability of fp.dp
    extension for -mcpu=cortex-r52.

Tested by building an arm-none-eabi GCC cross-compiler targeting Cortex-R52 and building an hello world with it. Also checked that the .fpu option created by GCC for -mcpu=cortex-r52 and -mcpu=cortex-r52+nofp.dp is as expected (respectively .fpu neon-fp-armv8 and .fpu fpv5-sp-d16

Is this ok for trunk?

Ok.
Thanks,
