https://gitlab.freedesktop.org/mesa/mes ... ble.h#L216 says I'm right, and GLES EXT_buffer_storage directly maps to GL ARB_buffer_storage.
The VC6 V3D hardware can support GLES 3.2, but under mesa it is currently failing conformance testing for reasons that are still being tracked down. I suspect that if the v3d driver claimed to do GLES 3.2 then it may automagically work.
Looking at some of our status emails from Igalia, they are fixing the GLES 3.1 conformance issues at present, so hopefully soon we'll be able to adopt that and you should get GLES EXT_buffer_storage.
