[OpenWrt-Devel,2/3] ath79: Prepare nand subtarget forSPI-NAND boards under Linux 4.19

From: Jeff Kletsky <git-commits@allycomm.com>

Linux 4.19 supplies the upstream spi-nand framework,
permitting porting and support of boards with SPI NAND.

  * Adjusted nand/target.mk to set KERNEL_PATCHVER:=4.19
    and provide FEATURES += squashfs nand

  * Updated config-default to provide current MTD and UBI support

  * Removed non-functional GL.iNet AR300M NAND target

[ adding Marty (author of ar300m-nand support) to the Cc loop ]

>   * Removed non-functional GL.iNet AR300M NAND target

you've probably missed some parts:

 package/boot/uboot-envtools/files/ath79:glinet,gl-ar300m-nand|\
 target/linux/ath79/base-files/etc/board.d/01_leds:glinet,gl-ar300m-nand|\
 target/linux/ath79/base-files/etc/board.d/02_network:   glinet,gl-ar300m-nand|\
 target/linux/ath79/dts/qca9531_glinet_gl-ar300m-nand.dts:       compatible = "glinet,gl-ar300m-nand", "qca,qca9531";

could you please make this ar300m-nand removal separate commit (probably first
in the series) and add Marty to the Cc?

It would be nice to make him aware about this possible device removal as he
might be interested in fixing of support for this device or in the other case,
he can possibly give you his Acked-by/Reviewed-by tag.

You can drop this comment, having this in the commit message is enough.
