On beaglebone black, it can so happen that PHY address
is not latched correctly on reset and board boots with
PHY responding to a different address than that
programmed in device-tree. For example, see this report:
https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J
Workaround this by fixing up device-tree passed to kernel
by using the PHY address detected in hardware.
Beaglebone itself uses only one ethernet port and its DT
currently uses phy_id (obsoleted). But the function has
been written to handle multiple ports and phy_id as well
as phy-handle to make the function more generically useful.

On some boards using TI CPSW, it may be possible that
PHY address was not latched correctly, and the actual
address that the phy responds on is different from that
set in device-tree. For example, see this problem report
on beaglebone black:
https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J
Add support to check for this condition and use the
detected phy address when its safe to do so.
Also, add a public API that exposes the phy address of
a given slave. This can be used to update device-tree that
is passed to Linux kernel.

The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location
is available and can be corrupted by loading ie. uImage or fitImage
headers there. Sometimes it could be beneficial to load the headers
elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we
still want to parse the image headers in some local onchip memory to
ie. extract firmware from that image.
Add the possibility to override the location where the headers get
loaded by introducing new function, spl_get_load_buffer() which takes
two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the
data that are to be loaded there -- and returns a valid buffer address
or hangs the system. The default behavior is the same as before, add
the offset to CONFIG_SYS_TEXT_BASE and return that address. User can
override the weak spl_get_load_buffer() function though.

In the current driver, OOB bytes are accessed in raw mode, and when a
page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the
driver must read the whole spare area (64 bytes in case of a 2k page,
16 bytes for a 512 page). The driver was only reading the free OOB
bytes, which was leaving some unread data in the FIFO and was somehow
leading to a timeout.
We could patch the driver to read ->spare_size + ->ecc_size instead of
just ->spare_size when READOOB is requested, but we'd better make
in-band and OOB accesses consistent.
Since the driver is always accessing in-band data in non-raw mode (with
the ECC engine enabled), we should also access OOB data in this mode.
That's particularly useful when using the BCH engine because in this
mode the free OOB bytes are also ECC protected.

This commit is needed to properly support the 8-bits ECC configuration
with 4KB pages.
When pages larger than 2 KB are used on platforms using the PXA3xx
NAND controller, the reading/programming operations need to be split
in chunks of 2 KBs or less because the controller FIFO is limited to
about 2 KB (i.e a bit more than 2 KB to accommodate OOB data). Due to
this requirement, the data layout on NAND is a bit strange, with ECC
interleaved with data, at the end of each chunk.
When a 4-bits ECC configuration is used with 4 KB pages, the physical
data layout on the NAND looks like this:
| 2048 data | 32 spare | 30 ECC | 2048 data | 32 spare | 30 ECC |
So the data chunks have an equal size, 2080 bytes for each chunk,
which the driver supports properly.
When a 8-bits ECC configuration is used with 4KB pages, the physical
data layout on the NAND looks like this:
| 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 64 spare | 30 ECC |
So, the spare area is stored in its own chunk, which has a different
size than the other chunks. Since OOB is not used by UBIFS, the initial
implementation of the driver has chosen to not support reading this
additional "spare" chunk of data.
Unfortunately, Marvell has chosen to store the BBT signature in the
OOB area. Therefore, if the driver doesn't read this spare area, Linux
has no way of finding the BBT. It thinks there is no BBT, and rewrites
one, which U-Boot does not recognize, causing compatibility problems
between the bootloader and the kernel in terms of NAND usage.
To fix this, this commit implements the support for reading a partial
last chunk. This support is currently only useful for the case of 8
bits ECC with 4 KB pages, but it will be useful in the future to
enable other configurations such as 12 bits and 16 bits ECC with 4 KB
pages, or 8 bits ECC with 8 KB pages, etc. All those configurations
have a "last" chunk that doesn't have the same size as the other
chunks.
In order to implement reading of the last chunk, this commit:
- Adds a number of new fields to the pxa3xx_nand_info to describe how
many full chunks and how many chunks we have, the size of full
chunks and partial chunks, both in terms of data area and spare
area.
- Fills in the step_chunk_size and step_spare_size variables to
describe how much data and spare should be read/written for the
current read/program step.
- Reworks the state machine to accommodate doing the additional read
or program step when a last partial chunk is used.

The Data Flash Control Register (NDCR) contains two types
of parameters: those that are needed for device identification,
and those that can only be set after device identification.
Therefore, the driver can't set them all at once and instead
needs to configure the first group before nand_scan_ident()
and the second group later.
Let's split pxa3xx_nand_config in two halves, and set the
parameters that depend on the device geometry once this is known.

The chunk size represents the size of the data chunks, which
is used by the controllers that allow to split transferred data.
However, the initial chunk size is used in a non-split way,
during device identification. Therefore, it must be large enough
for all the NAND commands issued during device identification.
This includes NAND_CMD_PARAM which was recently changed to
transfer up to 2048 bytes (for the redundant parameter pages).
Thus, the initial chunk size should be 2048 as well.
On Armada 370/XP platforms (NFCv2) booted without the keep-config
devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM
