63015d73f3 ARM: dts: am335x: Provide NAND ready pin
On these boards NAND ready pin status is avilable over
GPMC_WAIT0 pin.

For NAND we don't use GPMC wait pin monitoring but
get the NAND Ready/Busy# status using GPIOlib.
GPMC driver provides the WAIT0 pin status over GPIOlib.

Read speed increases from 7869 KiB/ to 8875 KiB/s
and write speed was unchanged at 5100 KiB/s.

Measured using mtd_speedtest.ko on am335x-evm.

db0f68529a ARM: dts: am335x: Disable wait pin monitoring for NAND
The NAND Ready/Busy# line is connected to GPMC_WAIT0 pin and
can't be used for wait state insertion for NAND I/O read/write.
So disable read/write wait monitoring as per Reference Manual's
suggestion [1].

0375214838 ARM: dts: am335x: Fix NAND device nodes
Add compatible id, GPMC register resource and interrupt
resource to NAND controller nodes.

The GPMC node will provide an interrupt controller for the
NAND IRQs.

system-on-chip.

The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board
NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit
Ethernet, CAN bus.

Current patch adds support:
UART0 and GPIO LED
