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.

7f6eecf580 Create the children devices for the SoC in atmelarm bus node, not in
the identify routine of the CPU.

0fb8b6b070 Export the interrupt status vector via soc_data. Set the interrupt
priorities in the AIC in the atmelarm driver before attaching the
children.  Delete redunant copies of the code.

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.

6e21b3a1b6 Go ahead and disable the interrupts for the DBGU the boot loader may
have left enabled after we detect the CPU, and remove the multiplely
copied code from the SoC modules.

d67febb24f Remove a useless bit of indirection. On all Atmel ARM products, irq 1
is the system IRQ, so use the define for it and get on with life.

19f4a07329 Collapse all copies of at91_add_child into at91.c. They were
logically identical before today, and actually identical after today's
changes.

89e57ebbb5 The system IRQ is always IRQ 1. Make it so. 2012-07-10 02:39:03 +00:00

9a5f8be0a7 Eliminate the AT91XXXX_BASE for each SoC. AT91_BASE is the right way
to spell this since we only have one AT91_BASE for all Atmel arm9 SoCs.

73a4b7a9d8 Enhance the Atmel SoC chip identification routines to account for more
SoC variants.  Fold the AT91SAM9XE chips into the AT91SAM9260
handling, where appropriate.  The following SoCs/SoC families are recognized:
	at91cap9, at91rm9200, at91sam9260, at91sam9261, at91sam9263,
	at91sam9g10, at91sam9g20, at91sam9g45, at91sam9n12, at91sam9rl,
	at91sam9x5
and the following variations are also recognized:
	at91rm9200_bga, at91rm9200_pqfp, at91sam9xe, at91sam9g45, at91sam9m10,
	at91sam9g46, at91sam9m11, at91sam9g15, at91sam9g25, at91sam9g35,
	at91sam9x25, at91sam9x35
This is only the identification routine: no additional Atmel devices
are supported at this time.

# With these changes, I'm able to boot to the point of identification
# on a few different Atmel SoCs that we don't yet support using the
# KB920X config file -- someday tht will be an ATMEL config file...
