- * Support added for the new WRT54G v2.2 and WRT54GS v1.1 "flags"
- * Without the flags set to 0x7, the above units will refuse to flash.
- *
- * Extensions:
- * -{0|1|2} sets {0|1} sets hw_ver flag to 0/1. {2} sets hw_ver to 1
- * and adds the new hardware "flags" for the v2.2/v1.1 units

-/* July 29, 2004
- *
- * This is a hacked replacement for the 'trx' utility used to create
- * wrt54g .trx firmware files. It isn't pretty, but it does the job
- * for me.
- *
- * As an extension, you can specify a larger maximum length for the
- * .trx file using '-m'. It will be rounded up to be a multiple of 4K.
- * NOTE: This space will be malloc()'d.
- *
- * August 16, 2004
- *
- * Sigh... Make it endian-neutral.
- *
- * TODO: Support '-b' option to specify offsets for each file.
- *
- * February 19, 2005 - mbm
- *
- * Add -a (align offset) and -b (absolute offset)

-/* Copyright (C) 1986 Gary S. Brown. You may use this program, or
- code or tables extracted from it, as desired without restriction.*/
-
-/* First, the polynomial itself and its table of feedback terms. The */
-/* polynomial is */
-/* 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+X^0 */
-/* Note that we take it "backwards" and put the highest-order term in */
-/* the lowest-order bit. The X^32 term is "implied"; the LSB is the */
-/* X^31 term, etc. The X^0 term (usually shown as "+1") results in */
-/* the MSB being 1. */
-
-/* Note that the usual hardware shift register implementation, which */
-/* is what we're using (we're merely optimizing it by doing eight-bit */
-/* chunks at a time) shifts bits into the lowest-order term. In our */
-/* implementation, that means shifting towards the right. Why do we */
-/* do it this way? Because the calculated CRC must be transmitted in */
-/* order from highest-order term to lowest-order term. UARTs transmit */
-/* characters in order from LSB to MSB. By storing the CRC this way, */
-/* we hand it to the UART in the order low-byte to high-byte; the UART */
-/* sends each low-bit to hight-bit; and the result is transmission bit */
-/* by bit from highest- to lowest-order term without requiring any bit */
-/* shuffling on our part. Reception works similarly. */
-
-/* The feedback terms table consists of 256, 32-bit entries. Notes: */
-/* */
-/* 1. The table can be generated at runtime if desired; code to do so */
-/* is shown later. It might not be obvious, but the feedback */
-/* terms simply represent the results of eight shift/xor opera- */
-/* tions for all combinations of data and CRC register values. */
-/* */
-/* 2. The CRC accumulation logic is the same for all CRC polynomials, */
-/* be they sixteen or thirty-two bits wide. You simply choose the */
-/* appropriate table. Alternatively, because the table can be */
-/* generated at runtime, you can start by generating the table for */
-/* the polynomial in question and use exactly the same "updcrc", */
-/* if your application needn't simultaneously handle two CRC */
-/* polynomials. (Note, however, that XMODEM is strange.) */
-/* */
-/* 3. For 16-bit CRCs, the table entries need be only 16 bits wide; */
-/* of course, 32-bit entries work OK if the high 16 bits are zero. */
-/* */
-/* 4. The values must be right-shifted by eight bits by the "updcrc" */
-/* logic; the shift must be unsigned (bring in zeroes). On some */
-/* hardware you could probably optimize the shift in assembler by */
-/* using byte-swap instructions. */

+/* 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+X^0 */
+/* Note that we take it "backwards" and put the highest-order term in */
+/* the lowest-order bit. The X^32 term is "implied"; the LSB is the */
+/* X^31 term, etc. The X^0 term (usually shown as "+1") results in */
+/* the MSB being 1. */
+
+/* Note that the usual hardware shift register implementation, which */
+/* is what we're using (we're merely optimizing it by doing eight-bit */
+/* chunks at a time) shifts bits into the lowest-order term. In our */
+/* implementation, that means shifting towards the right. Why do we */
+/* do it this way? Because the calculated CRC must be transmitted in */
+/* order from highest-order term to lowest-order term. UARTs transmit */
+/* characters in order from LSB to MSB. By storing the CRC this way, */
+/* we hand it to the UART in the order low-byte to high-byte; the UART */
+/* sends each low-bit to hight-bit; and the result is transmission bit */
+/* by bit from highest- to lowest-order term without requiring any bit */
+/* shuffling on our part. Reception works similarly. */
+
+/* The feedback terms table consists of 256, 32-bit entries. Notes: */
+/* */
+/* 1. The table can be generated at runtime if desired; code to do so */
+/* is shown later. It might not be obvious, but the feedback */
+/* terms simply represent the results of eight shift/xor opera- */
+/* tions for all combinations of data and CRC register values. */
+/* */
+/* 2. The CRC accumulation logic is the same for all CRC polynomials, */
+/* be they sixteen or thirty-two bits wide. You simply choose the */
+/* appropriate table. Alternatively, because the table can be */
+/* generated at runtime, you can start by generating the table for */
+/* the polynomial in question and use exactly the same "updcrc", */
+/* if your application needn't simultaneously handle two CRC */
+/* polynomials. (Note, however, that XMODEM is strange.) */
+/* */
+/* 3. For 16-bit CRCs, the table entries need be only 16 bits wide; */
+/* of course, 32-bit entries work OK if the high 16 bits are zero. */
+/* */
+/* 4. The values must be right-shifted by eight bits by the "updcrc" */
+/* logic; the shift must be unsigned (bring in zeroes). On some */
+/* hardware you could probably optimize the shift in assembler by */
+/* using byte-swap instructions. */
