9 This document describes the information about Xilinx Zynq U-Boot -
10 like supported boards, ML status and TODO list.
14 Xilinx Zynq-7000 All Programmable SoCs enable extensive system level
15 differentiation, integration, and flexibility through hardware, software,
16 and I/O programmability.
18 * zc702 (single qspi, gem0, mmc) [1]
19 * zc706 (dual parallel qspi, gem0, mmc) [2]
20 * zed (single qspi, gem0, mmc) [3]
21 * microzed (single qspi, gem0, mmc) [4]
23 - zc770-xm010 (single qspi, gem0, mmc)
24 - zc770-xm011 (8 or 16 bit nand)
26 - zc770-xm013 (dual parallel qspi, gem1)
30 ex. configure and build for zc702 board
31 $ make zynq_zc702_config
36 Zynq has a facility to read the bootmode from the slcr bootmode register
37 once user is setting through jumpers on the board - see page no:1546 on [5]
39 All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
42 board_late_init() will read the bootmode values using slcr bootmode register
43 at runtime and assign the modeboot variable to specific bootmode string which
44 is intern used in autoboot.
46 SLCR bootmode register Bit[3:0] values
47 #define ZYNQ_BM_NOR 0x02
48 #define ZYNQ_BM_SD 0x05
49 #define ZYNQ_BM_JTAG 0x0
51 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
52 bootmode strings at runtime.
56 - Added basic board configurations support.
57 - Added zynq u-boot bsp code - arch/arm/cpu/armv7/zynq
58 - Added zynq boards named - zc70x, zed, microzed, zc770_xm010/xm011/xm012/xm013
60 serial - drivers/serial/serial_zynq.c
61 net - drivers/net/zynq_gem.c
62 mmc - drivers/mmc/zynq_sdhci.c
63 spi - drivers/spi/zynq_spi.c
64 qspi - drivers/spi/zynq_qspi.c
65 i2c - drivers/i2c/zynq_i2c.c
66 nand - drivers/mtd/nand/raw/zynq_nand.c
67 - Done proper cleanups on board configurations
68 - Added basic FDT support for zynq boards
69 - d-cache support for zynq_gem.c
73 - Add FDT support on individual drivers
