Patch for unlocking all Intel flash that has instant locking on power up. The patch has been tested on Intel M18, P30 and J3D Strata Flash. 1. The automatic unlocking can be disabled for a particular partition in the map or the command line. a. For the bit mask in the map it should look like: .mask_flags = MTD_POWERUP_LOCK, b. For the command line parsing it should look like: mtdparts=0x80000(bootloader)lk 2. This will only unlock parts with instant individual block locking. Intel parts with legacy unlocking will not be unlocked.

The single-bit error correction was, well, incorrect. For determing which bit to correct it was using P1' P2' P4' P8' instead of P1 P2 P4 P8, and it was using P16' P32' P64' P128' P256' P512' P1024' P2048' instead of P16 P32 P64 P128 P256 P512 P1024 P2048.

The problem: NAND flashes have different amount of initial bad physical eraseblocks (marked as bad by the manufacturer). For example, for 256MiB Samsung OneNAND flash there might be from 0 to 40 bad initial eraseblocks, which is about 2%. When UBI is used as the base system, one needs to know the exact amount of good physical eraseblocks, because this number is needed to create the UBI image which is put to the devices during production. But this number is not know, which forces us to use the minimum number of good physical eraseblocks. And UBI additionally reserves some percentage of physical eraseblocks for bad block handling (default is 1%), so we have 1-3% of PEBs reserved at the end, depending on the amount of initial bad PEBs. But it is desired to always have 1% (or more, depending on the configuration). Solution: this patch adds an "auto-resize" flag to the volume table. The volume which has the "auto-resize" flag will automatically be re-sized (enlarged) on the first UBI initialization. UBI clears the flag when the volume is re-sized. Only one volume may have the "auto-resize" flag. So, the production UBI image may have one volume with "auto-resize" flag set, and its size is automatically adjusted on the first boot of the device.
