zynx zx212 dual-port ethernet card

hi! I'm confused about your words.I noticed that #define request_8xxirq request_irq in /include/asm-ppc/mpc8260.h ,so there should be no difference between request_irq()and request_8xxirq().Right? I have no other PCI card at hand,so I didn't boot with other card. I am running a 4 port ZX214

PPC RTC on I2C

[Matt] I always thought that one would implement some low-level ppc-specific i2c master access functions. These would be available via a few ppc_mds and one could have a generic i2c 'adapter' to call the functions. For RTC access, one would then have a i2c RTC implementation using
