AFAIK, u-boot just writes pre-defined values to the memory controller
registers. It doesn't do any chiptype/memsize detection. These values
are set for Sequoia and may not suite your board. So you probably need
to adjust the u-boot to make linux detect the memory size correctly.
Thanks,
Val.

With the ack quirks added we can use handle_level_irq for edge-triggered
interrupts. I'
after the ISR has de-asserted the external interrupt source.
Even if we ack the interrupt that we didn't handle (unmask/ack it at
the end of the handler, while next irq is already pending) it will not
de-assert the irq, untill we de-assert its exteral source.

This adds uic_mask_ack_irq() callback to PowerPC 4xx uic code
to avoid kernel crash. It is used for edge-triggered interrupts
by handle_uic_irq().

lways stays
asserted untill the external source is removed and ack'ed on UIC.
These have been tested on Sequoia PowerPC 440EPx board.
Thanks,
Valentine.

ign pointers here, not actually
reading the registers.
Also, looks like you unmap the fpga registers too early.
Thanks,
Valentine.

The following patches add PowerPC 440GRx Rainier board support.
The board is almost identical to Sequoia, but doesn't have USB
and FPU is not supported.
Thanks,
Valentine.
