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.

This will be used by nand_plat. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

nios2: fix r15 issue for gcc4

2010-05-28T14:56:03Z

The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

nios2: add gpio support

2010-05-28T14:56:03Z

This patch adds driver for a trivial gpio core, which is described in http://nioswiki.com/GPIO. It is used for gpio led and nand flash interface in u-boot. When CONFIG_SYS_GPIO_BASE is not defined, board may provide its own driver. Signed-off-by: Thomas Chou Tested-by: Ian Abbott Signed-off-by: Scott McNutt

nios2: add dma_alloc_coherent

2010-04-24T22:21:22Z

This function return cache-line aligned allocation which is mapped to uncached io region. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

nios2: add 64 bits swab support

2010-04-24T22:21:22Z

This patch adds 64 bits swab support. Most 32 bits processors use this. We need 64 bits swab for UBI. Signed-off-by: Thomas Chou Signed-off-by: Scott McNutt

Move architecture-specific includes to arch/$ARCH/include/asm

2010-04-13T07:13:12Z

This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser
