2013-01-05Work around MEMERASE ioctl for rk3066 compatibilitySergey 'Jin' Bostandzhyan1-0/+22
Due to a kernel bug and no available sources we have to work around the MEMERASE ioctl - if used, it hangs and never returns. I straced the original recovery executable and could see that it is simply calling write() with a bunch of zeroes instead of using MEMERASE. Added a hack that does the same and now the resulting TWRP recovery image works. Change-Id: I1b1c1c9e870e350776346bdca5d442c7ef565aa0

Pull in most TWRP sources Stub out partition management code Make it compile -- probably will not boot Kind of a mess but have to start somewhere

A few signed/unsigned comparison warnings were all that stood in the way of a clean clang build. Change-Id: Id8c47fcfa500a6ac164bddb855831cdc17d99847 Author: Edwin Vane <edwin.vane@intel.com> Reviewed-by: Tareq A Siraj <tareq.a.siraj@intel.com>

2010-11-03fix comparison of ECC stats before and after mtd readsDoug Zongker1-0/+2
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. Bug: 3162777 Change-Id: I5a13abd7243d2afd1d21bd98cbb233e5124b2e80
2010-09-15close update package before installing; allow remountDoug Zongker1-1/+1
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. Change-Id: Idfcc96c3da66083295177f729263560be58034e4

2010-01-13make offsets in firmware update header not point to bad blocksDoug Zongker1-4/+42
(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. http://b/2358012 - passion: failure to flash hboot (bad blocks?)

2009-07-01skip over all-zero blocks when reading MTD partitionDoug Zongker1-1/+12
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.
