[OpenWrt-Devel] [PATCH 2/3] ath79: Prepare nand subtarget for SPI-NAND boards under Linux 4.19

[Jeff Kletsky]

From: Jeff Kletsky <git-commits at 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
