[U-Boot] How to use the NEON instruction at u-boot?

[Kyungmin Park]

Hi,

Now I'm trying to use the NEON instruction at u-boot. but it's failed
and got the data abort.
Are there any way to use the NEON instruction at u-boot?

The main purpose is to use the neon memcpy as below.

        bge         1f
        // copies 4 bytes, destination 32-bits aligned
        vld4.8      {d0[0], d1[0], d2[0], d3[0]}, [r1]!
        vst4.8      {d0[0], d1[0], d2[0], d3[0]}, [r0, :32]!
1:      bcc         2f

Thank you,
Kyungmin Park
