11 This document describes the information about Xilinx Zynq U-Boot -
12 like supported boards, ML status and TODO list.
16 Xilinx Zynq-7000 All Programmable SoCs enable extensive system level
17 differentiation, integration, and flexibility through hardware, software,
18 and I/O programmability.
20 * zc702 (single qspi, gem0, mmc) [1]
21 * zc706 (dual parallel qspi, gem0, mmc) [2]
22 * zed (single qspi, gem0, mmc) [3]
23 * microzed (single qspi, gem0, mmc) [4]
25 - zc770-xm010 (single qspi, gem0, mmc)
26 - zc770-xm011 (8 or 16 bit nand)
28 - zc770-xm013 (dual parallel qspi, gem1)
32 ex. configure and build for zc702 board
33 $ make zynq_zc702_config
38 Zynq has a facility to read the bootmode from the slcr bootmode register
39 once user is setting through jumpers on the board - see page no:1546 on [5]
41 All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
44 board_late_init() will read the bootmode values using slcr bootmode register
45 at runtime and assign the modeboot variable to specific bootmode string which
46 is intern used in autoboot.
48 SLCR bootmode register Bit[3:0] values
49 #define ZYNQ_BM_NOR 0x02
50 #define ZYNQ_BM_SD 0x05
51 #define ZYNQ_BM_JTAG 0x0
53 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
54 bootmode strings at runtime.
58 - Added basic board configurations support.

63 net - drivers/net/zynq_gem.c
64 mmc - drivers/mmc/zynq_sdhci.c
65 mmc - drivers/mmc/zynq_sdhci.c
66 spi- drivers/spi/zynq_spi.c
67 i2c - drivers/i2c/zynq_i2c.c
68 - Done proper cleanups on board configurations
69 - Added basic FDT support for zynq boards
