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.
21 - zc702 (single qspi, gem0, mmc) [1]
22 - zc706 (dual parallel qspi, gem0, mmc) [2]
23 * zed (single qspi, gem0, mmc) [3]
24 * microzed (single qspi, gem0, mmc) [4]
26 - zc770-xm010 (single qspi, gem0, mmc)
27 - zc770-xm011 (8 or 16 bit nand)
29 - zc770-xm013 (dual parallel qspi, gem1)
33 # Configure for zc70x board
34 $ make zynq_zc70x_config
35 Configuring for zynq_zc70x board...
37 # Building default dts for zc702 board
40 # Building specified dts for zc706 board
41 $ make DEVICE_TREE=zynq-zc706
45 Zynq has a facility to read the bootmode from the slcr bootmode register
46 once user is setting through jumpers on the board - see page no:1546 on [5]
48 All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
51 board_late_init() will read the bootmode values using slcr bootmode register
52 at runtime and assign the modeboot variable to specific bootmode string which
53 is intern used in autoboot.
55 SLCR bootmode register Bit[3:0] values
56 #define ZYNQ_BM_NOR 0x02
57 #define ZYNQ_BM_SD 0x05
58 #define ZYNQ_BM_JTAG 0x0
60 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
61 bootmode strings at runtime.
65 - Added basic board configurations support.
