James Buren	581081a3df	mi4: replace chksum_crc32 with crc_32r This uses an equivalent algorithm but with a different initial value than we normally use (all bits off vs all bits on). Use the new crc_32r to replace the original MI4 crc32 implementation. This frees up some extra space on mi4 targets which gives us more room on a few very space constrained targets (sansa c200/e200, etc).

Frank Gevaerts	2b9e944021	Rework c200wipe to use proper partitioning and formatting code, which makes the code size-independent. Also support the e200 with this code. Apparently it's also possible to get the e200 in a state where .fmt files don't help. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30413 a1c6a512-1295-4272-9138-f99709370657	2011-09-02 21:34:28 +00:00

mi4: replace chksum_crc32 with crc_32r

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.

This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).

Rework c200wipe to use proper partitioning and formatting code, which makes the code size-independent.

Also support the e200 with this code. Apparently it's also possible to get the e200 in a state where .fmt files don't help.
