  "message": "SPI bitbanging: request/release bus\n\nSPI bitbanging on devices which speak SPI natively has a dual-use\nproblem: We need to shut down normal SPI operations to do the bitbanging\nourselves. Once we\u0027re done, it makes a lot of sense to reenable \"normal\"\nSPI operations again. Add request_bus/release_bus functions to struct\nbitbang_spi_master.\nAdd a bitbang shutdown function (not used yet).\nChange MCP SPI and Intel NIC SPI to use the new request/release bus\ninfrastructure.\nCosmetic changes to a few error messages (80 column limit).\n\nThere are multiple possible strategies for bus request/release:\n- Request at the start of a SPI command, release immediately afterwards.\n- Request at the start of a SPI multicommand, release once all commands\nof the multicommand are done.\n- Request on programmer init, release on shutdown.\nEach strategy has its own advantages. For now, we will stay with the\nfirst strategy which worked fine so far.\n\nCorresponding to flashrom svn r1171.\n\nSigned-off-by: Carl-Daniel Hailfinger \u003cc-d.hailfinger.devel.2006@gmx.net\u003e\nAcked-by: Uwe Hermann \u003cuwe@hermann-uwe.de\u003e\n",
