[PATCH 1/2] nvmem: kconfig: set i.MX OCOTP default y

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

If ARCH_MXC is selected, set NVMEM_IMX_OCOTP[*] default y which will make
nfs rootfs work since i.MX network driver needs read mac address from
fuse.

[PATCH 2/2] arm64: defconfig: remove IMX OCOTP

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

i.MX OCOTP has default settings as y in Kconfig, no need entries in
defconfig.

Given that ARCH_MXC is y is defconfig and making these drivers as 
default y will increase the arm64 defconfig kernel size.

Putting them in defconfig was also not welcomed. No good idea
from me how to address the nfsboot issue. We not use ramfs.

Thanks,
