2014-11-10ARC: Remove redundant PCI_IOBASE declarationThierry Reding
ARC's asm/io.h includes the asm-generic/io.h which already defines the PCI_IOBASE variable in exactly the same way, so it can be dropped from the architecture specific header. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-09-05ARC: Add read*_relaxed to asm/io.hMischa Jonker
Some drivers require these, and ARC didn't had them yet. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-02-15ARC: Add support for ioremap_prot APIGilad Ben-Yossef
Implement ioremap_prot() to allow mapping IO memory with variable protection via TLB. Implementing this allows the /dev/mem driver to use its generic access() VMA callback, which in turn allows ptrace to examine data in memory mapped regions mapped via /dev/mem, such as Arc DCCM. The end result is that it is possible to examine values of variables placed into DCCM in user space programs via GDB.
