From: Guo Ren <ren_guo@xxxxxxxxx>
C-SKY CPU is seperated into two ABIs:
- abiv1: mcore based ISA with ELF_NUM:39 and do not support FPU & VDSP.
(CPU: 610)
- abiv2: C-SKY own ISA with ELF_NUM:252 and support FPU & VDSP.
(CPU: 807, 810, 860)
BR2_GCC_TARGET_FLOAT_ABI will have a value for abiv1. Except the value
will always be "soft" because there's no FPU support in ck610, which is
the only core using abiv1.
