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).
