Bug Description
BUG DESCRIPTION
===============
The code for the copy of the .const section within the C boot
routine c_int0, for the C2x and C2xx devices can only copy a maximum
of 256 words. If the length of the .const section is larger than
256 then only the length mod 256 (length % 256) number of items are
transferred.
The problem is caused by use of the RPT to iterate the BLKP
instruction for transferring the data. Since RPT counter register
is only an 8-bit counter on the C2x/C2xx, this restricts the number
of items that can be transferred.
