      i2c/designware: Do not re-initialize bus if configured by coreboot · 9ee4a955
      Furquan Shaikh authored
      Coreboot is taking a lot of effort reading device-tree values for
      fall/rise time or lcnt/hcnt and calculating and configuring
      controller register values to ensure I2C bus speed is within limits
      when used in firmware. Depthcharge driver was resetting all those
      values by using default configuration. This resulted in I2C bus speed
      in depthcharge going beyond limits. (Noticed by sudden spike in H1 I2C
      frequency in depthcharge).
      This change updates the designware I2C driver to check if high and low
      cycle time registers are already configured and skip initialization
      of the bus completely.
      TEST=Verified that H1 I2C frequency is <400KHz in coreboot and in
      depthcharge. No spikes observed after jumping to depthcharge. Also, no
      errors seen while communicating with H1 in depthcharge.

      ps8751: enable software sync. · 5a086f5c
      Caveh Jalali authored
      this turns on ps8751 firmware update during software sync on
      reef/electro and derivative boards.
      testing on electro:
      with debug code enabled in the ps8751 driver (i.e. forced update),
      we can see the update taking place in the console logs.  when no update
      is needed, we simply see:
      ps8751.1: vendor 0x1da0 product 0x8751 device 0x0001 hw_rev A3 fw_rev 0x37
      reported from the update driver, verifying that we've enabled the
      update driver in the board file.
      we have a working design doc for firmware updates:
      also, spot checked nasher build to verify defconfig changes carry over
      to derivative boards.
      TEST=updated ps8751 firmware on electro

      Makefile: Fix default for LIBPAYLOAD_DIR · 83724941
      Julius Werner authored
      We're usually passing LIBPAYLOAD_DIR to depthcharge's Makefile, but it's
      also possible to omit that parameter and have it default to the location
      that libpayload would be in if depthcharge's source is located under
      Unfortunately, it looks like that hasn't been working right for a while.
      We're trying to source xcompile from libpayload before we're setting
      that default, and we're later passing the derived location of lpgcc to
      vboot without handling the possibility that LIBPAYLOAD_DIR was a
      relative path. This patch resolves both issues. Since LIBPAYLOAD_DIR is
      usually not set for the Kconfig pass of the Makefile, move the code down
      into the respective ifeq section.
      TEST=Build and booted depthcharge for Kevin without emerge.
