Hi All
I am using ARM based board.
In mine,
i did the following...
void __iomem *tcpm_base = ioremap_nocache(0x03B00000, 10*SZ_3MB);
Actually i didnt reserve the 30MB memory @ 0x3B00000. But still the call is
succesful and i am able to read the memory.
In the logs it is just showing a warning, to fix my driver as i am calling
ioremap() on system memory.
However if i try to write something on that memory, then only it is
calling panic()..
Don't you think it should throw panic()while calling the ioremap() itself.
Because this sounds like a serious violation...
What say?
