c2758 clk errata fixed in latest chips? Also what are the soc emulation options for software development before actual custom board comes?

Hi,

1. we are planning to build a custom board with ATOM c2758. saw an issue circulating in the net about clk. does it fixed in latest chips?

2. If we want to develop firmware before Board comes what are our options? is there a soc simulator/emulator available. 

3. does intel releases FSP for c2758?

Thanks in advance for your help,

Tiru
