Peng Fan f34ccce50a mmc: fsl_esdhc: drop CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT
CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT is not the correct method
to set I/O to 1.8. To boards that does not support vqmmc-supply,
use vs18_enable in fsl_esdhc_cfg. If regulator is supported,
use fixed 1.8V regulator for vqmmc-supply.

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.

* 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

 ex. configure and build for zc702 board
   $ make zynq_zc702_config
   $ make

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.
