[PATCH 0/3] Merge mkimage tool

[Josh Boyer]

The following patches merge the mkimage tool into the kernel.  This
utility is used by several arches to create a uImage file suitable for
booting with U-Boot.

As it stands today, a mkuboot.sh script is called, which searches for
the mkimage utility installed on the host system.  This is slightly
suboptimal as it prevents things like automated rebuilds of certain
platforms on those architectures.

This is currently based on the mkimage version found in U-Boot 1.3.1.
The tool is called mkubootimg in these patches, as mkimage is slightly
ambiguous outside of the U-Boot source tree.

Note: arch/powerpc the conversion in these patches as Paul's tree has
some changes that haven't hit Linus' tree yet.  I'll fixup arch/powerpc
as soon as these patches get merged.

[PATCH 1/3] Merge mkubootimg tool for building U-Boot images

[Josh Boyer]

Several platforms require the mkimage tool to generate a uImage file that is
used with U-Boot.  This brings the mkimage tool in-kernel to enable building
those platforms without having mkimage externally provided.  The tool is named
mkubootimg for better clarity.

This is currently based off of the version found in U-Boot 1.3.1.

+  Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The table is simply the CRC of all possible eight bit values.  This is all
+  the information needed to generate CRC's on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.

+ * Image Types
+ *
+ * "Standalone Programs" are directly runnable in the environment
+ *	provided by U-Boot; it is expected that (if they behave
+ *	well) you can continue to work in U-Boot after return from
+ *	the Standalone Program.
+ * "OS Kernel Images" are usually images of some Embedded OS which
+ *	will take over control completely. Usually these programs
+ *	will install their own set of exception handlers, device
+ *	drivers, set up the MMU, etc. - this means, that you cannot
+ *	expect to re-enter U-Boot except by resetting the CPU.
+ * "RAMDisk Images" are more or less just data blocks, and their
+ *	parameters (address, size) are passed to an OS kernel that is
+ *	being started.
+ * "Multi-File Images" contain several images, typically an OS
+ *	(Linux) kernel image and one or more data images like
+ *	RAMDisks. This construct is useful for instance when you want
+ *	to boot over the network using BOOTP etc., where the boot
+ *	server provides just a single image file, but you want to get
+ *	for instance an OS kernel and a RAMDisk image.
+ *
+ *	"Multi-File Images" start with a list of image sizes, each
+ *	image size (in bytes) specified by an "uint32_t" in network
+ *	byte order. This list is terminated by an "(uint32_t)0".
+ *	Immediately after the terminating 0 follow the images, one by
+ *	one, all aligned on "uint32_t" boundaries (size rounded up to
+ *	a multiple of 4 bytes - except for the last file).
+ *
+ * "Firmware Images" are binary images containing firmware (like
+ *	U-Boot or FPGA images) which usually will be programmed to
+ *	flash memory.
+ *
+ * "Script files" are command sequences that will be executed by
+ *	U-Boot's command interpreter; this feature is especially
+ *	useful when you configure U-Boot to use a real shell (hush)
+ *	as command interpreter (=> Shell Scripts).

Now that the mkubootimg tool is merged into the kernel, we can remove the unused
mkuboot.sh script.

i'm fairly certain sha1 is not needed.  the u-boot makefile has a bug
in the 1.3.1 release where mkimage depends on sha1.o but doesnt
actually use sha1 functions.  i posted a patch to u-boot mailing list
to get this dropped.  regardless, no need for the kernel to import it.

No need to yet anyway.  There are discussions on-going to make a new
image format that can do sha1 sums instead of crc32.  Either way is
fine with me, I just opted to include it now to keep it the same as
U-Boot and avoid having to include it in the future.

If you want an updated patch with the sha1 code removed, I can do
that.  Sam, Wolfgang?

yes, but i think the next image format is going to require quite a bit
of changes in the build system anyways, especially since with the
kernel you will want the option to produce either format, so simply
dropping the sha1 makes sense to me.  but i dont really care either
way, just making sure you're aware of the issue (and it sounds like
you are).

Yep, I am.  I plan on maintaining the in-kernel version too, as most
of the PPC 44x boards these days use U-Boot.  So I'll be sure to keep on
top of things.

Indeed, it would be nice to actually be CC'ed on the patch itself at the
time of submission without having to dig through the list archives for
it. Hopefully the next iteration gets this right, as well as Haavard's
email address ;-)

for a recent discussion on the ins and outs, multiple formats, options
and so forth passed to mk(u)image.  It looks like we're heading for 5 or
6 different kernel image formats for the ARM architecture. ;(

We do not want sha1.* files around because we expect them to be used. So I 
dropped those.
Otherwise I applied all three patches.
I will await one day for ack's from Russell and Paulus before
I push out the tree.

Ok, thanks.  As it really is no change from the current status quo,
I'll go with this until something happens from the discussion below.

Hm, that's a bit unfortunate indeed.  I'm not very familiar with ARM,
but is there a "majority" image format that is used?  If so, we could
have the kernel build system generate that by default for uImages.

If not, perhaps it would be better to remove the uImage stuff
completely for ARM as you hinted at in that thread.  The other
architectures don't seem to suffer from as many differences and are
probably OK.

[PATCH 1/3 v2] Merge mkubootimg tool for building U-Boot images

[Josh Boyer]

Several platforms require the mkimage tool to generate a uImage file that is
used with U-Boot.  This brings the mkimage tool in-kernel to enable building
those platforms without having mkimage externally provided.  The tool is named
mkubootimg for better clarity.

This is currently based off of the version found in U-Boot 1.3.1.

+ *	well) you can continue to work in U-Boot after return from
+ *	the Standalone Program.
+ * "OS Kernel Images" are usually images of some Embedded OS which
+ *	will take over control completely. Usually these programs
+ *	will install their own set of exception handlers, device
+ *	drivers, set up the MMU, etc. - this means, that you cannot
+ *	expect to re-enter U-Boot except by resetting the CPU.
+ * "RAMDisk Images" are more or less just data blocks, and their
+ *	parameters (address, size) are passed to an OS kernel that is
+ *	being started.
+ * "Multi-File Images" contain several images, typically an OS
+ *	(Linux) kernel image and one or more data images like
+ *	RAMDisks. This construct is useful for instance when you want
+ *	to boot over the network using BOOTP etc., where the boot
+ *	server provides just a single image file, but you want to get
+ *	for instance an OS kernel and a RAMDisk image.
+ *
+ *	"Multi-File Images" start with a list of image sizes, each
+ *	image size (in bytes) specified by an "uint32_t" in network
+ *	byte order. This list is terminated by an "(uint32_t)0".
+ *	Immediately after the terminating 0 follow the images, one by
+ *	one, all aligned on "uint32_t" boundaries (size rounded up to
+ *	a multiple of 4 bytes - except for the last file).
+ *
+ * "Firmware Images" are binary images containing firmware (like
+ *	U-Boot or FPGA images) which usually will be programmed to
+ *	flash memory.
+ *
+ * "Script files" are command sequences that will be executed by
+ *	U-Boot's command interpreter; this feature is especially
+ *	useful when you configure U-Boot to use a real shell (hush)
+ *	as command interpreter (=> Shell Scripts).

I added following comment to the changelog:
======
Note: This patchs trigger followings output from checkpatch.pl:
total: 45 errors, 144 warnings, 1097 lines checked

As this is based on a copy of SW from U-boot this is accepted as an
exception.
======

Next time please indicate result of checkpatch.pl run.
Usually I does not accept errors from checkpatch.pl (unless
checkpatch.pl has become utterly confused).

And I added Wolfgang as Cc:
