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 Zynq has a facility to read the bootmode from the slcr bootmode register
34 once user is setting through jumpers on the board - see page no:1546 on [5]
36 All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
39 board_late_init() will read the bootmode values using slcr bootmode register
40 at runtime and assign the modeboot variable to specific bootmode string which
41 is intern used in autoboot.
43 SLCR bootmode register Bit[3:0] values
44 #define ZYNQ_BM_NOR 0x02
45 #define ZYNQ_BM_SD 0x05
46 #define ZYNQ_BM_JTAG 0x0
48 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
49 bootmode strings at runtime.
53 - Added basic board configurations support.

55 - Added zynq boards named - zynq, zynq_dcc
57 serial - drivers/serial/serial_zynq.c
58 net - drivers/net/zynq_gem.c
59 mmc - drivers/mmc/zynq_sdhci.c
60 mmc - drivers/mmc/zynq_sdhci.c
61 spi- drivers/spi/zynq_spi.c
62 i2c - drivers/i2c/zynq_i2c.c
66 - Add zynq boards support - zc70x, zed, microzed, zc770
67 - Add zynq qspi controller driver
68 - Add zynq nand controller driver
69 - d-cache support for zynq_gem.c
70 - FDT support for zynq boards
71 - Need proper cleanups on board configurations
