Description boris.astardzhiev 2012-10-03 12:00:23 UTC 
I would like to contribute a new feature for the FreeBSD boot loader - a
command that calculates the CRC32 of a specified file name. It uses libz's CRC32
implementation.

While attempting to make libstand's nandfs to work adequately I've
experienced NAND flash page/block misreadings from U-Boot's API side. Therefore I was in a need of a tool that could prove that a file had been read correctly in this very stage of the FreeBSD boot process. So here it is.

In addition to the CRC calculation the size of the stipulated file is
printed as well.

Any comments will be appreciated - http://lists.freebsd.org/pipermail/freebsd-fs/2012-October/015288.html

Fix: See patch.

ad6f5f9ab52eeedca8cbdb325e78b33381bd0e2f created a crc for libsa, so this is now OBE as fixed. Thanks for anticipating our later need, and sorry we dropped it on the floor.
