[U-Boot] [PATCH 27/28] nios2: convert pk1c20 board to use cfi flash and spi flash

Thomas Chou thomas at wytron.com.tw
Fri Mar 19 08:43:52 CET 2010


The patch converts the pk1c20 board to use the common cfi flash
and spi driver.

The addressing of devices is changed to virtual address.
The args to writel() is changed to (val,port) in led.c.
