![]() With this change driver will benefit from existing phylib and thus custom phy functionality implemented in the driver will go away: * Instantiation of the driver is now much shorter - 2 parameters instead of 4. * Simplified phy management/functoinality in driver is replaced with rich functionality of phylib. * Support of custom phy initialization is now done with existing "board_phy_config". Note that after this change some previously used config options (driver-specific PHY configuration) will be obsolete and they are simply substituted with similar options of phylib. For example: * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled by default. * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise automatically the first discovered on MDIO bus phy will be used I believe there's no need now in "doc/README.designware_eth" because user only needs to instantiate the driver with "designware_initialize" whose prototype exists in "include/netdev.h".

# # Xilinx ZYNQ U-Boot # # (C) Copyright 2013 Xilinx, Inc. # # SPDX-License-Identifier: GPL-2.0+ # 1. About this This document describes the information about Xilinx Zynq U-Boot - like supported boards, ML status and TODO list. 2. Zynq boards Xilinx Zynq-7000 All Programmable SoCs enable extensive system level differentiation, integration, and flexibility through hardware, software, and I/O programmability. * zc70x - zc702 (single qspi, gem0, mmc) [1] - zc706 (dual parallel qspi, gem0, mmc) [2] * zed (single qspi, gem0, mmc) [3] * microzed (single qspi, gem0, mmc) [4] * zc770 - zc770-xm010 (single qspi, gem0, mmc) - zc770-xm011 (8 or 16 bit nand) - zc770-xm012 (nor) - zc770-xm013 (dual parallel qspi, gem1) 3. Building # Configure for zc70x board $ make zynq_zc70x_config Configuring for zynq_zc70x board... # Building default dts for zc702 board $ make # Building specified dts for zc706 board $ make DEVICE_TREE=zynq-zc706 4. Bootmode Zynq has a facility to read the bootmode from the slcr bootmode register once user is setting through jumpers on the board - see page no:1546 on [5] All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins on [5]. board_late_init() will read the bootmode values using slcr bootmode register at runtime and assign the modeboot variable to specific bootmode string which is intern used in autoboot. SLCR bootmode register Bit[3:0] values #define ZYNQ_BM_NOR 0x02 #define ZYNQ_BM_SD 0x05 #define ZYNQ_BM_JTAG 0x0 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot" bootmode strings at runtime. 5. Mainline status - Added basic board configurations support. - Added zynq u-boot bsp code - arch/arm/cpu/armv7/zynq - Added zynq boards named - zc70x, zed, microzed, zc770_xm010, zc770_xm012, zc770_xm013 - Added zynq drivers: serial - drivers/serial/serial_zynq.c net - drivers/net/zynq_gem.c mmc - drivers/mmc/zynq_sdhci.c mmc - drivers/mmc/zynq_sdhci.c spi- drivers/spi/zynq_spi.c i2c - drivers/i2c/zynq_i2c.c - Done proper cleanups on board configurations - Added basic FDT support for zynq boards - d-cache support for zynq_gem.c 6. TODO - Add zynq boards support - zc770_xm011 - Add zynq qspi controller driver - Add zynq nand controller driver - Add FDT support on individual drivers [1] http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC702-G.htm [2] http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC706-G.htm [3] http://zedboard.org/product/zedboard [4] http://zedboard.org/product/microzed [5] http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf -- Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Sun Dec 15 14:52:41 IST 2013
