[ 2010-10-22 14:45:52 by rt ]
R: 1) DMA may not work if user space buffer is in highmem (check
/proc/meminfo for HighTotal>0).
2) After unloading the VME4L module a subsequent modprobe may fail.
3) Cosmetics.
4) Not compilable for kernel version > 2.6.26.
5) DMA mode is not supported by Non-BLT spaces.
M: 1) Replaced page_address()/virt_to_bus().
2) Removed
3) Some register debug prints were swapped at little endian machines.

-----[ Release-2.11 ]-----
[ 2009-07-09 16:10:24 by rt ]
R: 1.) All: Large zero-copy DMAs (>64k at PLDZ002; >408k at TSI148)
read/write wrong data.
2.) All: "Kernel access of bad area" may occur if VME4L_Read/Write() is
used with size>0x80000.
3.) All: System may freeze if kernel is compiled with CONFIG_SMP set.
4.) All: Not compilable with kernel 2.5.3..2.6.9 or >2.6.21.
5.) All: Example tool for system controller functions is missing in
MDIS wizard.
6.) TSI148: Access to slave window register space is not working anymore
if another slave window is requested.

Notes
- This driver can be built using the Linux kernel build system. However, it is recommended to use the MDIS system package build environment instead (13MD05-90).
- Please note that on A17 this driver needs to be compiled into the kernel statically.
- Please refer to the VME 4 Linux installation instructions for more detailed information!
- For all features on A13/A15, a recent VME PLD for A13/A15 is required.
