7e70b6be7f Deleted check for equality in flash image header and partition
header.

Skipping flash after just checking a 1K header is
incorrect in the case where something scribbles over
the partition after the header because flash_image
would not be able to rewrite the whole
partition due to this check.

Also, Samsung devices use a combined boot and
recovery image where the header is the same even if the
initramfs changes and these do not get flashed even
if the boot.img is actually different due to different
appended initramfs.

4123b58299 recovery: Autodetection of device flash type
Detect flash type at runtime rather than requiring this to be set in the
device configuration. The detection is based on the existence of /proc/mtd,
/proc/emmc, or /dev/block/bml1.

5d6309e77f fix comparison of ECC stats before and after mtd reads
ECC errors are found by comparing the result of ioctl(ECCGETSTATS)
before and after the read.  But if an error was found causing us to go
to the next block, we'd compare the stats before the *first* read to
the stats after the second (third, fourth, etc.) reads, so we'd read
to the end of the partition without ever succeeding.  Fix logic so we
compare the values before and after each read independently.

8e5e4dada7 close update package before installing; allow remount
Close the update package before invoking the binary, to allow the
installer to unmount /cache if it wants to.  Add a function to allow
remounting of a mount as read-only.

22d79a5c5e make offsets in firmware update header not point to bad blocks
(This is being cherry-picked from master.)

hboot will apparently fail to install if the first block of the image
(the one pointed to by the offset in the block 0 header) is a bad
block.  (Hopefully it handles subsequent bad blocks.)

This change makes the MTD write code keep track of the bad blocks it
has skipped over, so that the offset in the header can be adjusted to
be the address of the first successfully written block.

bec02d57fb skip over all-zero blocks when reading MTD partition
We fail to detect certain bad blocks (marked in the factory as bad, I
think?) when reading mtd partitions.  These come back as a block of
all zeros.  Since it's fairly unlikely a legitimate boot or recovery
block will contain 128k of zeros, change mtdutils to skip over such
blocks.

Arve says https://review.source.android.com/10535 may be a long-term
fix for this, but he isn't yet sure.
