NEW YORK, June 22 (Reuters) - Byron Trott, the ex-Goldman Sachs banker and adviser to Warren Buffett, has raised more than $2 billion for his start-up investment firm BDT Capital Partners, according to a report in the Financial Times.

Trott, who has been described as Buffett's favorite banker, left Goldman in March. His Chicago-based firm focuses on family-owned and entrepreneurial companies, investing capital and providing advice.

BDT continues to seek additional commitments and has also begun to add other senior dealmakers including Don McLellan, former head of mergers and acquisitions at Motorola (MOT.N), the FT said, quoting people familiar with the matter.

Trott gained fame as adviser to Buffett's Berkshire Hathaway (BRKa.N), helping him through a series of deals.
