1. About this

This document describes the information about Xilinx Zynq U-Boot -
like supported boards, ML status and TODO list.

2. Zynq boards

Xilinx Zynq-7000 All Programmable SoCs enable extensive system level
differentiation, integration, and flexibility through hardware, software,
and I/O programmability.

* zc70x
  - zc702 (single qspi, gem0, mmc) [1]
  - zc706 (dual parallel qspi, gem0, mmc) [2]
* 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)

3. Building

 # Configure for zc70x board
   $ make zynq_zc70x_config
     Configuring for zynq_zc70x board...

 # Building default dts for zc702 board
   $ make

 # Building specified dts for zc706 board
   $ make DEVICE_TREE=zynq-zc706

4. 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]

All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
on [5].

board_late_init() will read the bootmode values using slcr bootmode register
at runtime and assign the modeboot variable to specific bootmode string which
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

"modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
bootmode strings at runtime.

5. 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, zc770_xm012, zc770_xm013
- Added zynq drivers:
  serial - drivers/serial/serial_zynq.c
  net - drivers/net/zynq_gem.c
  mmc - drivers/mmc/zynq_sdhci.c
  mmc - drivers/mmc/zynq_sdhci.c
  spi-  drivers/spi/zynq_spi.c
  i2c - drivers/i2c/zynq_i2c.c
- Done proper cleanups on board configurations
- Added basic FDT support for zynq boards
- d-cache support for zynq_gem.c

6. TODO

- Add zynq boards support - zc770_xm011
- Add zynq qspi controller driver
- Add zynq nand controller driver
- Add FDT support on individual drivers
