Hi all,
These patches add support for machines with ECONA CNS3xxx ARM11
MPcore (ARMv6) dual-core processors. Note that this is very basic
support, there is no support for SMP or fancy peripheral devices
as found in CNS3xxx SOCs (though, as shown in patches 3/4 and 4/4
we'll add these features soon).
Patches 1/4 and 2/4 have no external dependencies except for
mach-types update.
Patches 3/4 and 4/4 are a bit trickier. Patch 3/4 depends on a few
sdhci updates that are in -mm tree, and patch 4/4 depends on some
ahci rework that is in libata-dev tree ('next' branch).
Thanks!

This patch adds a very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors. Specifically, CNS3420VB rev 1.3 board
is supported.
With this patch CNS3420VP board is able to boot up to the userspace,
with a console available on UART0.
Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.

CNS3xxx chips have AHCI-compatible SATA controller. This patch adds
the support using generic ahci_platform driver.

Can you not supply this via a built-in command line or a command line
from the boot loader?

This should be defined as the maximum address of the vmalloc area,
which should be independent of PAGE_OFFSET.

So I assume by this your platform can boot without having a processor of
any kind?
If not, why allow the user to disable the option?

I'd put the validation board support code into a patch of its own,
separate from the SoC support...

Yep, mem=128M is actually specified in the defconfig, and
this fixup is just a leftover. Will remove.

Ah, vmalloc has no fixed start address. Will fix.
But then arm/mm/mmu.c:create_mapping() wrongly assumes that vmalloc
starts at PAGE_OFFSET? At least it has 'md->virtual >= PAGE_OFFSET &&
md->virtual < VMALLOC_END' check, and prints 'overlaps vmalloc space'
error.

No it does not. You can't create device mappings inbetween PAGE_OFFSET
and VMALLOC_END, and that is what the test you point out is doing.
The print can be extended to be "overlaps kernel direct mapped RAM and vmalloc space"
but I think that's getting excessively long.
