The AFS v2 partition type appear in later ARM reference designs
such as RealView, Versatile Express and the 64bit Juno Development
Platform.
The image informations is padded with a 32bit word (4 bytes) on
the 32bit platforms and a 64bit word (8 bytes) on the 64bit
platforms. The boot monitor source code gives at hand that this
is because the first entry in the struct mapped over the image
information is a "next" pointer for a linked list, filled in
by firmware after reading in the info block, and always zero
in the flash. We adjust padding by checking what padding gives
the right checksum.
This was tested on:
- Integrator/AP (v1 partitions)
- RealView PB11MPCore (v2 32bit partitions)
- Juno Development System (v2 64bit partitions)
All systems display the images in flash very nicely as separate
partitions, e.g on Juno:
4 afs partitions found on MTD device 8000000.flash
Creating 4 MTD partitions on "8000000.flash":
0x000000040000-0x0000000c0000 : "fip"
0x000000ec0000-0x0000018c0000 : "Image"
0x000000f00000-0x000000f40000 : "juno"
0x000003ec0000-0x000003f00000 : "bl1"

This simplifies the AFS partition parsing to make the code
more straight-forward and readable.
Before this patch the code tried to calculate the memory required
to hold the partition info by adding up the sizes of the strings
of the names and adding that to a single memory allocation,
indexing the name pointers in front of the struct mtd_partition
allocations so all allocated data was in one chunk.
This is overzealous. Instead use kstrdup and bail out,
kfree():ing the memory used for MTD partitions and names alike
on the errorpath.
In the process rename the index variable from idx to i.

The Sharp SL Series (Zaurus) PXA handhelds have 16/64/128M of NAND flash
and share the same layout of the first 7M partition, managed by Sharp FTL.
GPL 2.4 sources: http://support.ezaurus.com/developer/source/source_dl.asp
The purpose of this self-contained patch is to add a common parser and
remove the hardcoded sizes in the board files (these devices are not yet
converted to devicetree).
Users will have benefits because the mtdparts= tag will not be necessary
anymore and they will be free to repartition the little sized flash.
The obsolete bootloader can not pass the partitioning info to modern
kernels anymore so it has to be read from flash at known logical addresses.
(see http://www.h5.dion.ne.jp/~rimemoon/zaurus/memo_006.htm )
In kernel, under arch/arm/mach-pxa we have already 8 machines:
MACH_POODLE, MACH_CORGI, MACH_SHEPERD, MACH_HUSKY, MACH_AKITA, MACH_SPITZ,
MACH_BORZOI, MACH_TOSA.
Lost after the 2.4 vendor kernel are MACH_BOXER and MACH_TERRIER.
Almost every model has different factory partitioning: add to this the
units can be repartitioned by users with userspace tools (nandlogical)
and installers for popular (back then) linux distributions.
The Parameter Area in the first (boot) partition extends from 0x00040000 to
0x0007bfff (176k) and contains two copies of the partition table:
...
0x00060000: Partition Info1 16k
0x00064000: Partition Info2 16k
0x00668000: Model 16k
...
The first 7M partition is managed by the Sharp FTL reserving 5% + 1 blocks
for wear-leveling: some blocks are remapped and one layer of translation
(logical to physical) is necessary.
There isn't much documentation about this FTL in the 2.4 sources, just the
MTD methods for reading and writing using logical addresses and the block
management (wear-leveling, use counter).
It seems this FTL was tailored with 16KiB eraesize in mind so to fit one
param block exactly, to have two copies of the partition table on two
blocks.
Later pxa27x devices have same size but 128KiB erasesize and less blocks
(56 vs. 448) but the same schema was adopted, even if the two tables are
now in the same eraseblock.
For the purpose of the MTD parser only the read part of the code was taken.
The NAND drivers that can use this parser are sharpsl.c and tmio_nand.c.

working on non-hacky method of checking rootfs format) but it's not
really a subject of this change.
