Hi,
"The kernel also allows hardcoded mapping
of IO regions into its virtual address space through the
io_block_mapping interface."
Can u tell me how this is in current arch/powerpc. Also does it mean
that whatever be the size of the ram > 768 MB there is not going to be
much improvement in perf

Hi,
I am creating a simple program which will try to read the board ID of the
PPC440EPx thru BCSR but when I load it, it gives me "Data Read PLB Error".
I am not sure if I missed out something.
I would really appreciate it if somebody could help me on this.
I have posted the source code below
Fixed. It turns out it was because I'm using VMWare to run Linux on my
windows computer. I booted up Linux natively and it stepped through code
very fast even in multi threaded apps.

Probably should be bus_num = 0

Thanks Ben,
Here it is
static struct fsl_spi_platform_data k_platform_data = {
.initial_spmode = 0,
.bus_num = 1,
.max_chipselect = 1,
/* board specific information */
.activate_cs = k_cs_activate,
.deactivate_cs = k_cs_deactivate,
.sysclk =266,
};

No, it maps 768MB of RAM in this manner.

Hi Paul,
I'm just wondering what are your latest thoughts about this patch
(http://patchwork.ozlabs.org/linuxppc/patch?id=14707).

Just call ioremap() as usual. It will understand the > 4G
