This change adds the correct Sbl_Hdr instead of Mbn_Hdr, since
sbl header is different than normal Mbn_Hdr, and adds the sbl
header size as 80.
SBL in nand starts with preamble before the sbl header, so here
it adds the preamble for header start address as well as
src, sig and cert offset values.

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.

This patch is to support DK01-C3 dts which is required
for standard profile in linux 4.4 kernel.Linux 3.14 kernel
does not have DK01-C3, hence it uses DK01-C1 config.

This change will look for existence of file /sys/sec_upgrade/sec_auth
if the file exists, it performs image authentication with the new
approach i.e TZ enabled mechanism.
It reads all the sections of the single image and writes each
section's type and image file path in /sys/sec_upgrade/sec_auth.
If a written section image is a proper signed image, then it will
return success else will cause the failure.
