Subject: [PATCH v6 00/29] nios2 Linux kernel port
This is the 6th version of patchset adds the Linux kernel port for Nios II
processor from Altera. All of the feedback from v5 patchseries has been
addressed. Note, only patch #1, #7 and #21 have non-trivial changes.
Thanks to all who provided feedback on the previous version.
About Nios II Cores
-------------------
Nios II is a 32-bit embedded-processor architecture designed specifically for the
Altera family of FPGAs.
More information is available at http://www.altera.com/devices/processor/nios2/ni2-index.html
Instruction set and architecture overview documents can be found on the
following page:
http://www.altera.com/literature/lit-nio2.jsp
Nios2 GCC port is in mainline and will be in the FSF 4.9 release.
The patchset are based on v3.18-rc3 and can also be found in the following git tree:
git://git.rocketboards.org/linux-socfpga-next.git nios2-upstream
v6:
* time: change from setup_irq to request_irq
* time: move num_called to nios2_time_init()
* time: remove checking for period==0
* time: change to use statically allocation for nios2 clock structures
* time: remove ARCH_HAS_READ_CURRENT_TIMER and use lpj_fine
* io: remove unused outs{b,w,l}, ins{b,w,l}, out{b,w,l} and in{b,w,l}
* remove __divdi3 and __udivdi3 sysmbol export
* add description to futex.h
