Subject: oxnas: clean-up NAND driver to fix probing issue
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=61f27ca3e4e1509ccb5abb01e9892ab90b8bc0cf;p=openwrt%2Fstaging%2Flinusw.git

oxnas: clean-up NAND driver to fix probing issue

A re-write of the driver based on xway_nand.c and constants as
well as the cmd_ctrl() function from the original oxnas_nand.c
resulted in a extremely similar looking file (see diffsize),
and fixes the issue of NAND not being detected on newer kernels.
