Looking for open source firmware supporting Scrypt for Antminer L3+

[maxpla3]

I am looking for open source firmware which implements the Scrypt algorithm on Antminer L3+. I'd like to be able to customize the parameters of the Scrypt algorithm or even rewrite it completely.

I'm a professional programmer but have no experience with ASICs thus far.

To specify my problem in more detail:

The Scrypt function is declared as

Code:

key = Scrypt(password, salt, N, r, p, derived-key-len)

I'd like to pass a list of parameters [password, salt, N, r, p, derived-key-len] to the Antminer L3+ and obtain a list of keys for those parameters.

How could I achieve this or is this even possible?
