  "message": "dirtyjtag_spi: Add DJTAG2 support\n\nThe new DJTAG2 protocol supports special command modifiers to speed\nthings up:\n\n* NO_READ allows a write without returning the sampled MISO data.\n* EXTEND_LENGTH allows to send 32B extra per transfer.\n\nAs SPI flash commands are basically half-duplex, we utilize NO_READ\nto send all the write data in a first loop and then receive data in\na second loop. Only flash writes can benefit from this and due to\ntheir programming delay the difference is marginal ~2%.\n\nLong reads, OTOH, benefit from the increased transfer size and we\nare about 45% faster.\n\nTested with DJTAG2 on a Blue Pill (STM32F103).\n\nChange-Id: Ie38b309f5865c7704c6b2a85e7437fe2621623d3\nSigned-off-by: Nico Huber \u003cnico.h@gmx.de\u003e\nReviewed-on: https://review.coreboot.org/c/flashrom-stable/+/73265\nTested-by: build bot (Jenkins) \u003cno-reply@coreboot.org\u003e\nReviewed-by: Jean THOMAS \u003cvirgule@jeanthomas.me\u003e\n",
