-Intel Cherry Hill specific instructions for bare mode:
-
-This uses Intel FSP for Braswell platform. Download it from Intel FSP website,
-put the .fd file to the board directory and rename it to fsp.bin.
-
-Extract descriptor.bin and me.bin from the original BIOS on the board using
-ifdtool and put them to the board directory as well.
-
-Note the FSP package for Braswell does not ship a traditional legacy VGA BIOS
-image for the integrated graphics device. Instead a new binary called Video
-BIOS Table (VBT) is shipped. Put it to the board directory and rename it to
-vbt.bin if you want graphics support in U-Boot.
-
-Now you can build U-Boot and obtain u-boot.rom
-
-$ make cherryhill_defconfig
-$ make all
-
-An important note for programming u-boot.rom to the on-board SPI flash is that
-you need make sure the SPI flash's 'quad enable' bit in its status register
-matches the settings in the descriptor.bin, otherwise the board won't boot.
-
-For the on-board SPI flash MX25U6435F, this can be done by writing 0x40 to the
-status register by DediProg in: Config > Modify Status Register > Write Status
-Register(s) > Register1 Value(Hex). This is is a one-time change. Once set, it
-persists in SPI flash part regardless of the u-boot.rom image burned.
