Created an attachment (id=1886)

add the SAM9 processor family to the AT91 hal.

Hello,

this patch restructures the AT91 Hal in a way that it is more easy
than before to add new members of the SAM9 Processor family.

This work was initially based on the G45 Port by Richard Rauch.
however significant bug-fixes and new features were added by Bernd Edlinger.

The patch contains support for the following processors:
- support for AT91SAM9G45-EK
- support for AT91SAM9G20-EK
- support for AT91SAM9260-EK
- RedBoot (as second level boot loader together with the Atmel Sam-BA boot
code)
- ARM AT91 MMU: added Access Protection against NULL-Pointer accesses
- ARM AT91 MMU: added Code Protection against self-modifying code
- ARM AT91 Code- and Data-Cache: added support
- ARM AT91 I2C: added support
- ARM AT91 Serial: support for more than 4 UARTs
- ARM AT91 ENET: support for multicasts
- ARM AT91 ENET: PHY-Polling or Interrupt-driven detection of Link changes
- ETH_PHY: added support for DP83640 PHY
- ETH_PHY: support for enabling PHY Interrupts
- ETH_PHY: support for Interrupt-driven SMI communication

The contents of this patch are:
hal.diff : changes to the eCos hal to add new processors to the AT91 platform.
i2c.diff : a simlpe i2c driver for the AT91SAM9XXX.
serial.diff : extension of the serial driver to more than 4 uarts + Caching.
spi.diff : fixes Caching.
eth.diff : fixes Caching, implements multicasts, interrupt driven PHY.
This also restructures the eth_phy component, in a way that should not
break existing ports, but opens a way for them to benefit of interrupt
driven PHY interface.

Note: the CYGHWR_DEVS_ETH_PHY_DP8384X was split up into
CYGHWR_DEVS_ETH_PHY_DP83847, CYGHWR_DEVS_ETH_PHY_DP83848
and CYGHWR_DEVS_ETH_PHY_DP83640,
because these parts are *not* pin compatible, thus you better know what
you use.

hal_powerpc.diff : had to undo the renaming of CYGHWR_DEVS_ETH_PHY_DP83847,
sorry for that...
