40 * The user interface starts numbering for Flash banks with 1
41 * for historical reasons.
45 * this routine looks for an abbreviated flash range specification.
46 * the syntax is B:SF[-SL], where B is the bank number, SF is the first
47 * sector to erase, and SL is the last sector to erase (defaults to SF).
48 * bank numbers start at 1 to be consistent with other specs, sector numbers
51 * returns: 1 - correct spec; *pinfo, *psf and *psl are
53 * 0 - doesn't look like an abbreviated spec
54 * -1 - looks like an abbreviated spec, but got
55 * a parsing error, a number out of range,
56 * or an invalid flash bank.
