The way the driver uses the HW and SW\nsequencer relies on some programmed register settings and hence creates\nunneeded dependencies with the underlying BIOS/bootloader. For example,\nthe driver unfortunately does not work as expected when booting from\nIntel Baytrail FSP based bootloaders like U-Boot, as the Baytrail FSP\ndoes not set up some SPI controller settings to make the driver happy.\nNow such limitation has been removed with this series.\n\n\nBin Meng (10):\n spi-nor: intel-spi: Fix number of protected range registers for\n BYT/LPT\n spi-nor: intel-spi: Remove useless 'buf' parameter in the HW/SW cycle\n spi-nor: intel-spi: Fix broken software sequencing codes\n spi-nor: intel-spi: Check transfer length in the HW/SW cycle\n spi-nor: intel-spi: Use SW sequencer for BYT/LPT\n spi-nor: intel-spi: Remove 'Atomic Cycle Sequence' in\n intel_spi_write()\n spi-nor: intel-spi: Don't assume OPMENU0/1 to be programmed by BIOS\n spi-nor: intel-spi: Remove the unnecessary HSFSTS register RW\n spi-nor: intel-spi: Rename swseq to swseq_reg in 'struct intel_spi'\n spi-nor: intel-spi: Fall back to use SW sequencer to erase\n\n drivers/mtd/spi-nor/intel-spi.c | 209 +++++++++++++++++++++++++++++-----------\n 1 file changed, 151 insertions(+), 58 deletions(-)"}
