nios2: move nios2.h to arch asm directory

2014-08-30T09:48:43Z

The nios2.h is nios2 cpu specific, and should go arch asm directory. Signed-off-by: Thomas Chou

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

2014-08-30T09:48:43Z

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. Signed-off-by: Thomas Chou

nios2: Pseudo implement dcache_status/enable/disable()

2011-10-28T01:50:13Z

AFAIK the NIOS2 architecture does not have any possibility to dynamically switch off the data cache. So _status() always reports 1 and _enable/_disable() just issue a flush of everything. For example, common/cmd_elf.c depends on these symbols. Signed-off-by: Joachim Foerster Signed-off-by: Thomas Chou

do_reset: unify duplicate prototypes

2010-11-28T20:47:24Z

The duplication of the do_reset prototype has gotten out of hand, and they're not all in sync. Unify them all in command.h. Signed-off-by: Mike Frysinger

nios2: fix out of reach case for do_reset

2010-08-20T02:15:49Z

There is a limitation (or bug?) of nios2 toolchain. The nios2 gcc didn't generate correct code when the reset vector is passed as a constant. It just generated a direct "call", which was wrong when the reset vector was not located in the same 256MB span as u-boot. The "Nios II Processor Reference Handbook" said, "call can transfer execution anywhere within the 256 MByte range determined by PC31..28. The Nios II GNU linker does not automatically handle cases in which the address is out of this range." So we have to use registered "callr" instruction to do the job.
