Are the following miners going to be supported?
BW L21
Innosilicon A5
M1 BTC Miner
In general, Awesome Miner works fine with all standard compliant miners. Almost all popular ASIC miners do provide a Cgminer compatible API, making it possible to manage and monitor them from Awesome Miner.
I actually don't know about the support for those you list - maybe you can try? You can download and use the free version of Awesome Miner from the web site.
