NANDs with page size of lesser than and equal to 2K are
reaching EOL. They are bing replaced with NANDs of
page size 4K and above.
To support this we have to extend the eccpos field

Add support to use second and third I2C bus, too.
Bus 0 is still the default, but by calling i2c_set_bus_num(1/2) before doing
I2C accesses, code can switch to bus 1 and 2, too. Don't forget to switch
back afterwards, then.

The syndrome based page read/write routines store ECC, and possibly other
"OOB" data, right after each chunk of ECC'd data. With ECC chunk size of
512 bytes and a large page (2KiB) NAND, the layout is:
data-0 OOB-0 data-1 OOB-1 data-2 OOB-2 data-3 OOB-3 OOB-leftover
Where OOBx is (prepad, ECC, postpad). However, the current "raw" routines
use a traditional layout -- data OOB, disregarding the prepad and postpad
values -- so when they're used with that type of ECC hardware, those calls
mix up the data and OOB. Which means, in particular, that bad block
tables won't be found on startup, with data corruption and related chaos
ensuing.
The current syndrome-based drivers in mainline all seem to use one chunk
per page; presumably they haven't noticed such bugs.
Fix this, by adding read/write page_raw_syndrome() routines as siblings of
the existing non-raw routines; "raw" just means to bypass the ECC
computations, not change data and OOB layout.

Sometimes, inside NetLoop, eth_halt() is called before eth_init() has
been called. This is harmless except for free() calls to pointers
which have not been allocated yet.
This patch initializes those pointers to NULL and allocates them only
the first time. This way we can get rid of free calls in halt callback.
This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.

This patch fixes erroneous access to the ethernet PHY which broke the driver.
1. Selector field in the auto-negotiation register must be 0x00001 for
using 802.3, not 0x00000 which is reseved.
2. Access to the PHY address specified by CONFIG_FEC_MXC_PHYADDR, not
0x0 fixed address.
This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.
Now using proper defines for auto-negotiation register.

This patch fixes a problem only seen very occasionally on Canyonlands.
The NOR flash interface (CFI driver) doesn't work reliably in all cases.
Erasing and/or programming sometimes doesn't work. Sometimes with
an error message, like "flash not erased" when trying to program an
area that should have just been erased. And sometimes without any error
messages. As mentioned above, this problem was only seen rarely and with
some PLL configuration (CPU speed, EBC speed).
Now I spotted this problem a few times, when running my Canyonlands with
the following setup (chip_config):
1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100
Changing the EBC configuration to not release the bus into high
impedance state inbetween the transfers (ATC, DTC and CTC bits set to 1
in EBC0_CFG) seems to fix this problem. I haven't seen any failure
anymore with this patch applied.

The asm-arm/unaligned.h includes linux/unaligned/access_ok.h
This file is unsafe to be used on ARM, since it does an unaligned memory
accesses which fails on ARM.
Lookin at Linux the basic difference seems to be the header
"include/asm-arm/unaligned.h". The Linux version of "unaligned.h"
does *not* include "access_ok.h" at all. It includes "le_byteshift.h"
and "be_byteshift.h" instead.

commit 70ed869e broke fsl pcie end-point initialization.

This reverts commit 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc.
There isn't any need to modify the API for fsl_pci_init_port to pass the
status of host/agent(end-point) status. We can determine that
internally to fsl_pci_init_port. Revert the patch that makes the API
change.
