Hi Tom,
this series adds U-Boot port to Xtensa, configurable processor architecture from Tensilica, Inc., now Cadence Design Systems Inc.
Preparation patches clean up OpenCores 10/100 MBit driver, enable it to be used with dedicated packet memory and with gigabit PHY. Two patches add proper xtensa bits: changes to shares files and contents of arch/xtensa. One more patch adds sample xtensa CPU configuration -- Diamond 232. One more patch adds xtfpga board family that consists of Avnet LX60, LX110 and LX200 and Xilinx ML605 and KC705 FPGA boards configured with xtensa bitstream.
The whole series is also available in the following git tree:
git://github.com/jcmvbkbc/u-boot-xtensa.git tags/xtensa-for-mainline-20140820
The port has been done mainly by Chris Zankel. I've been maintaining it internally for some time now and I'll maintain it upstream.
Chris Zankel (5): net/ethoc: support private memory configurations xtensa: add support for the xtensa processor architecture [1/2] xtensa: add support for the xtensa processor architecture [2/2] xtensa: add core information for the dc232b processor xtensa: add support for the 'xtfpga' evaluation board
Max Filippov (3): net/ethoc: fix warnings from ethoc_read/ethoc_write net/ethoc: don't advertise gigabit on the connected PHY Makefile: allow overriding '-ansi' in LDPPFLAGS
