southbridge/intel/common/smbus: Add do_i2c_block_write()
Intel Braswell supports i2c block writes using SMBus controller. This support is missing in actual smbus routines. Add do_i2c_block_write() which is a based on do_smbus_block_write() but also write first byte to SMBHSTDAT1. The caller needs to configure the SMBus controller in i2c mode. In i2c mode SMBus controller will send the next sequence: SMBXINTADD, SMBHSTDAT1, SMBBLKDAT .. SMBBLKDAT To ensure the the command is send over the bus the SMBHSTCMD register must be written also BUG=N/A TEST=Config eDP for LCD display on Facebook FBG-1701 Change-Id: I40f8c0f5257a62398189f36892b8159052481693 Signed-off-by: Frans Hendriks <fhendriks@eltan.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/30800 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
