* fix CRC32 calculation for sysupgradeMarkus Wigge2010-07-271-3/+5
| | | | | | | | | | | | | | | | * reduce image size for CRC calculation by fs_mark size sysupgrade sometimes failed for me and I noticed that it was due to incorrect CRC values in trx-header after performing it. It seems that the fs_mark was completely included in the calculation and that it was nevertheless modified by sysupgrade while appending the jffs data. This only occurs for the first boot after sysupgrade as the flashmap driver recalculates the CRC to an even smaller area when it boots. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@22396 3c298f89-4303-0410-b956-a3cf2f4a3e73

* tools/firmware-utils: enhance mktplinkfw utilityGabor Juhos2010-07-131-9/+278
| | | | | | | | | | | | Attached patch enhances the mktplinkfw utility: 1. existing firmware files in TP-Link format can now be inspected, showing eg. the used offsets 2. optionally the kernel and rootfs parts can be extracted (saves calculations for dd) 3. when generating firmwares, kernel entry point, load address and rootfs offset can be overwritten (for experienced users) Patch-by: Pieter "Fate" Hollants <pieter@hollants.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@22169 3c298f89-4303-0410-b956-a3cf2f4a3e73
