43d1af0df3 Neither of these systems has PCI, but they do have ohci interface, so 
fix comments.

954bfb8bbf Add new at91sam9g45 support and sn9g45 board to the ATMEL kernel. 
Adapt SN9G45 board support to cope with multi-board.

0ff8c4269b Document the dataflash/mmc-sd issue. Add umass driver and usb. Boot 
off da0s1a instead of ate0.  Note that MMC/SD is slot B.  Until I
switch over to NAND boot, dataflash booting will preclude having SD
cards inserted at boot, so this last bit is untested.

My SAM9260-EK not boots to multi-user prompt.

e69d4e1fbd Turns out the ETHERNUT5 isn't anything like the SAM9260-EK. Make this 
board init match better: UART1 instead of UART2, No RMMI, no SPI0, SPI1

bed6d97e74 Trim read/write sizes to 128 bytes. Pages are only 128 bytes in size. 
Writes larger than this will wrap to the same page.  Reads larger than
this are permitted, but why take chances.

1665e3cdfe Fix typo in comment. 
spibus uses cs= rather than addr=, so fix hints to use that (nop since
	spibus cs defaults to 0, and at91_spi assumes 0).

d68081b0b1 Update partitions to reflect "sam9 demo" defaults. 
Update i2c devices to just include the eeprom.
Update dataflash chip select to be CS 1 (this doesn't work yet and
	needs changes to at91_spi and the spibus infrastructure).

86bce74937 Move unmask IRQ function call up to nexus device level. 
FDT-enabled targets were broken after r238043 that relies
on device up the hierarchy to properly setup interrupt.
nexus device for ARM platforms did job only partially:
setting handler but not unmasking interrupt. Unmasking
was performed by platform code.

a68d1f48b9 Complete the transition away from newbus to populate the children to 
the linker set of CPU modules.  The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful.  delay and cpu_reset now work much earlier in the
boot process.

691b3c3238 Make the SoC stuff a little more modular, and start to move away from 
having the CPU device that's a child of atmelarm that does stuff.

o Create a linker_set for the support fucntions for the SoCs.
o Rename soc_data to soc_info.
o Move the delay and reset function pointers to new soc_data struct
o Create elements for all known SoCs
o Add lookup of the SoC we found, and print a warning if it isn't one
  we know about.

bb64064e5d Opt-in rather than opt-out of the SoC. We don't really support 
running with multiple SoCs compiled in very well anyway, so this just
wastes space.  As more and more SoCs arrive in the tree, it is better
to edit one master file that builds them all than many board files.
