Which specific authors and literary works about saints and Sai Baba are mentioned in Chapter 2 as precursors to the Sai Satcharitra?

Chapter 2 references several earlier authors and their works to provide context for the new text. It mentions Mahipati, who was inspired to write saint biographies in the year 1700 (Shaka), composing four books including *Bhakta-Vijay* and *Santa-Vijay*. Following him, Das Ganu is credited with writing *Bhakta-Lilamrut*, which contains three chapters on Shri Sai's life, and *Santa-Kathamrut*. The chapter also notes Raghunath-Savitri’s *Bhajanmala* and, for Gujarati readers, miraculous stories written by Amidas and Bhavani Metha. Lastly, it refers to a series of stories being published in Pune by devotees under the name 'Sai Prabha'.
