Chen-Yu Tsai bab972948e rockchip: rk3328: Add support for ROC-RK3328-CC board 
The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:

  - 1/2/4 GB DDR4 DRAM
  - eMMC connector for optional module
  - micro SD card slot
  - 1 x USB 3.0 host port
  - 2 x USB 2.0 host port
  - 1 x USB 2.0 OTG port
  - HDMI video output
  - TRRS connector with audio and composite video output
  - gigabit Ethernet
  - consumer IR receiver
  - debug UART pins

The ROC-RK3328-CC has the enable pin of the SD card power switch tied
to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is
muxed by default. SDMMC0_PWREN is an active high signal controlled by
the MMC controller, however the switch enable is active low, and
pulled low (enabled) by default to make things work on boot.

As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable
power to the card. The default GPIO state for the pin is pull-down and
input, which doesn't require extra configuration when paired with the
external pull-down and active low switch.

Deal with this by enabling regulator support in SPL, and setting
"u-boot,dm-spl" for the regulator and other device nodes needed for
muxing the pin.

The device tree file is synced from the Linux kernel next-20200324.

README.zfs 

This patch series adds support for ZFS listing and load to u-boot.

To Enable zfs ls and load commands, modify the board specific config file with
#define CONFIG_CMD_ZFS

Steps to test:

1. After applying the patch, zfs specific commands can be seen
   in the boot loader prompt using
	UBOOT #help

	zfsload- load binary file from a ZFS file system
	zfsls  - list files in a directory (default /)

2. To list the files in zfs pool, device or partition, execute
	zfsls <interface> <dev[:part]> [POOL/@/dir/file]
	For example:
	UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/

3. To read and load a file from an ZFS formatted partition to RAM, execute
	zfsload <interface> <dev[:part]> [addr] [filename] [bytes]
	For example:
	UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage
