Subject: [U-Boot] am335x board i2c_probe fails from nand boot
Date: Thu, 5 Jan 2017 12:09:26 +0200	[thread overview]
Message-ID: <CADnUhn3bFUMPOXwM4rSMtw-etb0G6XBhGf6uA9x8f9jXq0evcw@mail.gmail.com> (raw)
In-Reply-To: <CADnUhn3f0dg-kXyxzMgbCN7wC8ZC368LBjdRtvj8dT6vYyHkqQ@mail.gmail.com>

FIXME!! Pretty much everything I claim below is wrong and am335x_evm.h
correct.
Only the last notice is not totally wrong as space reserver for
NAND.u-boot-spl-os is not 0x2000.
