+About this
+----------
This document describes the information about Xilinx Zynq U-Boot -
like supported boards, ML status and TODO list.
-2. Zynq boards
+Zynq boards
+-----------
Xilinx Zynq-7000 All Programmable SoCs enable extensive system level
differentiation, integration, and flexibility through hardware, software,
* 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)
+ - zc770-xm010 (single qspi, gem0, mmc)
+ - zc770-xm011 (8 or 16 bit nand)
+ - zc770-xm012 (nor)
+ - zc770-xm013 (dual parallel qspi, gem1)

+Building
+--------
-3. Building
+configure and build for zc702 board::
- ex. configure and build for zc702 board
$ make zynq_zc702_config
$ make
-4. Bootmode
+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]
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
+
+.. code-block:: c
+
+ #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
+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/xm011/xm012/xm013
- Added zynq drivers:
- serial - drivers/serial/serial_zynq.c
- net - drivers/net/zynq_gem.c
- mmc - drivers/mmc/zynq_sdhci.c
- spi - drivers/spi/zynq_spi.c
- qspi - drivers/spi/zynq_qspi.c
- i2c - drivers/i2c/zynq_i2c.c
- nand - drivers/mtd/nand/raw/zynq_nand.c

+
- Done proper cleanups on board configurations
- Added basic FDT support for zynq boards
- d-cache support for zynq_gem.c
-6. TODO
+TODO
+----
+
+Add FDT support on individual drivers
