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" Cc: Ryan Harkin <ryan.harkin@linaro.org> Acked-by: Liviu Dudau <liviu.dudau@arm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Richard Weinberger <richard@nod.at>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
