nios2: change virt_to_phys to use physaddr_mask in global data

2015-11-06T01:14:11+00:00

As virt_to_phys() is used a lot in DMA transfer, change it
to use physaddr_mask in global data. This will save an "if"
statement and get a little faster.

nios2: convert cache flush to use dm cpu data

2015-10-22T23:58:20+00:00

Convert cache flush to use dm cpu data.

The original cache flush functions are written in assembly
and use CONFIG_SYS_{I,D}CACHE_SIZE... macros. It is difficult
to convert to use cache configuration in dm cpu data which is
extracted from device tree.

The cacheflush.c of Linux nios2 arch uses cpuinfo structure,
which is very close to our dm cpu data. So we copy and modify
it to arch/nios2/lib/cache.c to replace the old cache.S.

nios2: convert nios2 cpu to driver model

2015-10-22T23:37:03+00:00

Convert nios2 cpu to driver model. The cpu parameters are
extracted from device tree and saved to global data structure.
We will use them to replace the custom_fpga.h .

The nios2.h is nios2 cpu specific, and should go arch asm
directory.

nios2: divide nios2-io.h into each specific drivers and remove it

2014-08-30T09:48:43+00:00

The nios2-io.h defines hardware registers and bits of several FPGA
IP cores. It could be divided in to the specific drivers, including
altera timer, altera sysid, altera uart and altera jtag uart. The
altera pio and altera spi drivers use their own hardware definitions.
The removal of nios2-io.h will help modularity and maintenance.
