----- ------ -------- ----------------------------------------------
|
||
|
|
1.00 hbm 08/19/2010 First Release
|
||
|
|
1.00 nm 05/25/2011 Updated for minor doxygen corrections
|
||
|
|
1.02a sg 05/16/2012 Made changes for doxygen and moved some function
|
||
|
|
header from the xdmaps.h file to <a class="el" href="xdmaps_8c.html">xdmaps.c</a> file
|
||
|
|
Other cleanup for coding guidelines and CR 657109
|
||
|
|
and CR 657898
|
||
|
|
1.03a sg 07/16/2012 changed inline to __inline for CR665681
|
||
|
|
1.04a nm 10/22/2012 Fixed CR# 681671.
|
||
|
|
1.05a nm 04/15/2013 Fixed CR# 704396. Removed warnings when compiled
|
||
|
|
with -Wall and -Wextra option in bsp.
|
||
|
|
05/01/2013 Fixed CR# 700189. Changed XDmaPs_BuildDmaProg()
|
||
|
|
function description.
|
||
|
|
Fixed CR# 704396. Removed unused variables
|
||
|
|
UseM2MByte & MemBurstLen from XDmaPs_BuildDmaProg()
|
||
|
|
function.
|
||
|
|
1.07a asa 11/02/13. Made changes to fix compilation issues for iarcc.
|
||
|
|
Removed the PDBG prints. By default they were always
|
||
|
|
defined out and never used. The PDBG is non-standard for
|
||
|
|
Xilinx drivers and no other driver does something similar.
|
||
|
|
Since there is no easy way to fix compilation issues with
|
||
|
|
the IARCC compiler around PDBG, it is better to remove it.
|
||
|
|
Users can always use xil_printfs if they want to debug.
