Subject: powerpc/83xx: add NAND support for the MPC8360E-RDK boards
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1fb25be1e74498d389e4de819a6d1b174d6ccb7c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

powerpc/83xx: add NAND support for the MPC8360E-RDK boards

The StMicro NAND chip (512Mbit, 64MB) is connected to the local bus,
the first local bus' user-programmable machine is configured by the
firmware to work with NAND chips.

QE GPIO pin is used to poll the NAND's Ready-Not-Busy signal.
