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.

The Samsung Galaxy S bootloader apparently expects the kernel to be flashed to BML-managed flash - bad erase blocks will be mapped from a reservoir area.
CWM however just skips bad blocks, the usual procedure for mtd-accessed flash.
Consequently, the bootloader sees a corrupt zImage, and will usually crash when the kernel initializes.
This of course will only happen when the "boot" partition has bad blocks.
This patch was written by "eifert" and adds a tool called "bml_over_mtd" for flashing boot images which takes care of bad blocks and maps them to a reservoir area, like BML does.

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.

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.

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.

(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.

With the recovery image being installed by applypatch, the flash_image
tool isn't needed any more. Continue to build it for eng just in case
it's handy for debugging.
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.
