Buffer overflow was happening during read from ART
partition. MMC reading API uses block count so this
patch allocates required size temp buffer and copies
the ethernet MAC address data from this temp buffer.

To save space in NOR flash, environment loading from flash is
handled differently for NOR and NAND. The size for NOR flash
environment is taken from partition size itself.

dcache is enabled only during boot from flash.
During JTAG recovery, dcache_enable is skipped
to avoid cache issues in recovery environment.

This patch makes mmc driver dcache aware to keep
the mmc functionality intact, with or without dcache
is enabled.
flush_cache used here does both clean and invalidate
cache thus preventing data loss during unaligned access,
if any.

This patch adds the support on nand driver to work
when dcache is on.
flush_dcache_range will do both clean and invalidate.
To avoid any data loss when an un-aligned buffer used
in RX path, before giving buffer to bam and after bam
updates the data in buffer, buffer will be flushed.

In case of 11ad dock (AK01), 8033 phy needs to be reset,
before switch initialization. GPIO32 is configured to
reset phy.

Some of the newer nand parts can have bit flips in an erased
page due to the process technology used. In this case, ipq
nand controller is not able to identify that page as an erased
page. In case of bitflips, the ECC engine tries to correct the
data and then it generates the uncorrectable error. Now, this
data is not equal to original raw data.
Following logic is being added to identify the erased
codeword bitflips.
1. Maintain the bitmasks for the codewords which generated
uncorrectable error.
2. Read the raw data again in temp buffer and count the
number of zeros. Since spare bytes are unused in ECC layout and
won’t affect ECC correctability so no need to count number of
zero in spare bytes.
3. If the number of zero is below ECC correctability then it
can be treated as erased CW. In this case, make all the data/oob
of actual user buffers as 0xff.

Following are the major issues in current implementation
1. The mtd layer expects the driver to return non-negative
integer representing the maximum number of bitflips that were
corrected on any one ecc region. The mtd layer takes care of
returning EUCLEAN based on returned number.
2. The read should return the complete data in case of
EBADMSG so move the EBADMSG check in the main read function.

1. assign ecc strength in mtd structure which will be used by
mtd layer
2. Initialize bitflip_threshold with 3*4 of ecc strength so
that MTD layer will return EUCLEAN if number of ecc correction
are more than bitflip_threshold.
