[U-Boot] (G)PIO access trends, architecture independant solutions?

2010-08-11 Thread Reinhard Meyer
Hello all, recently a patch for soft-i2c has been accepted that uses gpio_* functions. Supposedly they are generic, but grep-ing shows that such functions only exist in the nios2 architecture. Every architecture seems to have their own similiar but not identical way for gpio access. At91 even has
