+Subject: [PATCH] cmcurl: link librt
+
+When cmake is linked against LibreSSL, there might be an indirect
+dependency on librt on certain systems if LibreSSL's libcrypto uses
+clock_gettime() from librt:
+
+    [ 28%] Linking C executable LIBCURL
+    .../lib/libcrypto.a(getentropy_linux.o): In function `getentropy_fallback':
+    getentropy_linux.c:(.text+0x16d): undefined reference to `clock_gettime'
+    getentropy_linux.c:(.text+0x412): undefined reference to `clock_gettime'
+    collect2: error: ld returned 1 exit status
+    make[5]: *** [Utilities/cmcurl/LIBCURL] Error 1
+
+Modify the cmcurl CMakeLists.txt to check for clock_gettime() in librt
+and unconditionally link the rt library when the symbol is found.

+ *
+ * This is a hacked replacement for the 'addpattern' utility used to
+ * create wrt54g .bin firmware files.  It isn't pretty, but it does
+ * the job for me.
+ *
+ * Extensions:
+ *  -v allows setting the version string on the command line.
+ *  -{0|1} sets the (currently ignored) hw_ver flag in the header
+ *      to 0 or 1 respectively.
+ */
+
+/* January 12, 2005
+ *
+ * Modified by rodent at rodent dot za dot net
+ * 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
+*/
+
+/* January 1, 2007
+ *
+ * Modified by juan.i.gonzalez at subdown dot net
+ * Support added for the AG241v2  and similar
+ *
+ * Extensions:
+ *  -r #.# adds revision hardware flags. AG241v2 and similar.
+ *
+ * AG241V2 firmware sets the hw_ver to 0x44.
+ *
+ * Example: -r 2.0
+ *
+ * Convert 2.0 to 20 to be an integer, and add 0x30 to skip special ASCII
+ * #define HW_Version ((HW_REV * 10) + 0x30)  -> from cyutils.h

+/*
+ * JCG firmware update images consist of a 512 byte header and a
+ * modified uImage (details below) as the payload.
+ *
+ * The payload is obfuscated by XORing it with a key that is generated
+ * from parts of the header. Fortunately only non-essential parts of
+ * the header are used for this and zeroing them results in a zero
+ * key, effectively disabling the obfuscation and allowing us to use
+ * clear text payloads.
+ *
+ * The mandatory parts of the header are:
+ *
+ * - A magic string of "YSZJ" at offset 0.
+ * - A value of 1 at offset 39 (header format version?)
+ * - A CRC32 checksum of the payload at offset 504.
+ * - A CRC32 checksum of the header at offset 508.
+ *
+ * An image constructed by these rules will be accepted by JCG's
+ * U-Boot in resuce mode via TFTP and the payload will be written to
+ * the flash starting at offset 0x00050000.
+ *
+ * JCG's U-Boot does check the content or size of the payload
+ * image. If it is too large, it wraps around and overwrites U-Boot,
+ * requiring JTAG to revive the board. To prevent such bricking from
+ * happening, this tool refuses to build such overlong images.
+ *
+ * Using -m is possible to set the maximum size of the payload.
+ * Otherwise the default MAXSIZE will be used.
+ * For an 8Mb flash, the corresponding maxsize is:
+ * 8 * 1024 * 1024 - 5 * 64 * 1024 = 8388608 - 327680 = 8060928
+ *
+ * Two more conditions have to be met for a JCG image to be accepted
+ * as a valid update by the web interface of the stock firware:
+ *
+ *   - The bytes at offsets 109 and 111 in the header must be a binary
+ *   representation of the first two components of the firmware
+ *   version as displayed in the update web form, or it will be
+ *   rejected as "incorrect product".
+ *
+ *   - The payload must start with a valid uImage header whose data
+ *   CRC checksum matches the whole rest of the update file rather
+ *   than just the number of bytes specified in the size field of the
+ *   header.
+ *
+ * This last condition is met by JCG's original firmware images,
+ * because they have both, kernel and rootfs inside the uImage and
+ * abuse the last four bytes of the name field to record the offset of
+ * the file system from the start of the uImage header. This tool
+ * produces such images when called with -k and -r, which are meant to
+ * repack the original firmware after modifying the file systen,
+ * e.g. to add debugging tools and enable shell access.
+ *
+ * In contrast, OpenWrt sysupgrade images consist of a uImage that
+ * only contains the kernel and has the rootfs appended to it. Hence,
+ * the CRC over kernel and file system does not match the one in the
+ * uImage header. Fixing this by adjusting the uImage header is not
+ * possible, because it makes the uImage unusable for booting. Instead
+ * we append four "patch" bytes to the end of the file system, that
+ * are calculated to force the checksum of kernel+fs to be the same as
+ * for the kernel alone.

+//
+// NOTE: The kernel block size is used to know the offset of the rootfs
+// in the image file.
+//
+// The system writes in the uImage partition until the end of uImage
+// is reached, after that, the system jumps to the offset specified with the -k
+// parameter and begin writing at the beginning of the rootfs MTD partition.
+//
+// If the -k parameter is the size of the original uImage partition, the system
+// continue writing in the rootfs partition starting from the last block
+// that has been wrote. (This is useful if the new kernel size is
+// different from the original one)
+//
+// Example:
+// ------------------------------------------
+// Creating 7 MTD partitions on "ath-nor0":
+// 0x000000000000-0x000000010000 : "u-boot"

+// 0x000000030000-0x000000040000 : "config"
