Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
25+
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.
26+
27+
Polynomials over GF(2) are represented in binary, one bit per coefficient,
28+
with the lowest powers in the most significant bit. Then adding polynomials
29+
is just exclusive-or, and multiplying a polynomial by x is a right shift by
30+
one. If we call the above polynomial p, and represent a byte as the
31+
polynomial q, also with the lowest power in the most significant bit (so the
32+
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
33+
where a mod b means the remainder after dividing a by b.
34+
35+
This calculation is done using the shift-register method of multiplying and
36+
taking the remainder. The register is initialized to zero, and for each
37+
incoming bit, x^32 is added mod p to the register if the bit is a one (where
38+
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
39+
x (which is shifting right by one and adding x^32 mod p if the bit shifted
40+
out is a one). We start with the highest power (least significant bit) of
41+
q and repeat for all eight bits of q.
42+
43+
The table is simply the CRC of all possible eight bit values. This is all
44+
the information needed to generate CRC's on data a byte at a time for all
45+
combinations of CRC register values and incoming bytes.

92+
* "RAMDisk Images" are more or less just data blocks, and their
93+
* parameters (address, size) are passed to an OS kernel that is
94+
* being started.
95+
* "Multi-File Images" contain several images, typically an OS
96+
* (Linux) kernel image and one or more data images like
97+
* RAMDisks. This construct is useful for instance when you want
98+

* "Multi-File Images" start with a list of image sizes, each
103+
* image size (in bytes) specified by an "uint32_t" in network
104+
* byte order. This list is terminated by an "(uint32_t)0".
105+
* Immediately after the terminating 0 follow the images, one by
106+
* one, all aligned on "uint32_t" boundaries (size rounded up to
107+
* a multiple of 4 bytes - except for the last file).
108+
*
109+
* "Firmware Images" are binary images containing firmware (like
110+
* U-Boot or FPGA images) which usually will be programmed to
111+
* flash memory.
112+
*
113+
* "Script files" are command sequences that will be executed by
114+
* U-Boot's command interpreter; this feature is especially
115+
* useful when you configure U-Boot to use a real shell (hush)
116+
* as command interpreter (=> Shell Scripts).
