- 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).
