[U-Boot] [PATCH 00/28] u-boot next: a generic approach for nios2 arch

[Thomas Chou]

These patches are for next u-boot release. I udnerstand the merge window is
not opened yet. But there are quite a few things to review, so please
allow me submit them early.

This is a generic approach to port u-boot for nios2 boards. We try to ease
the porting of a new nios2 design. We will rely on tools generated header
file which contains the devices base address, instead of entering the hex
numbers by hand.

Thomas Chou (28):
  nios2: add nios2-generic board
  cfi flash: add status polling method for amd flash
  serial: move altera uart driver to drivers/serial
  serial: move altera jtaguart driver to drivers/serial
  serial: move yanu driver to drivers/serial
  spi: add altera spi controller support
  net: add opencore 10/100 ethernet mac support
  net: add altera triple speeds ethernet mac support
  nios2: change asm-nios2/io.h to compatible with nios2 linux
  nios2: add asm-nios2/errno.h
  nios2: add local_irq_enable/disable to asm-nios2/system.h
  nios2: use bitops from linux-2.6 asm-generic
  nios2: fix __fswab64 link error with asm-nios2/byteorder.h
  nios2: add dma_alloc_coherent with asm-nios2/dma-mapping.h
  nios2: add gpio support with asm-nios2/gpio.h
  nios2: move timer handler from interrupt.c to timer.c
  nios2: define text_base in start.S for linker script
  nios2: pass command line and initrd to linux
  nios2: board init for eth, no flash, nand and mmc
  nios2: fix writel in board/altera/common/epled.c
  nios2: add cf ide init and reset handler
  nios2: add gpio led driver
  nios2: convert ep1c20 board to use cfi flash and spi flash
  nios2: convert ep1s10 board to use cfi flash
  nios2: convert ep1s40 board to use cfi flash
  nios2: convert pci5441 board to use cfi flash
  nios2: convert pk1c20 board to use cfi flash and spi flash
  nios2: add struct stat support in linux/stat.h
