The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

This patch changes all absolute SYS_XY registers to offsets from the
SYS block base, prefixes them with AU1000 to avoid silent failures due
to changed addresses, and introduces helper functions to read/write
them.
No functional changes, comparing assembly of a few select functions shows
no differences.

Convert the Alchemy platform to register the ohci-platform driver, now that
the ohci-platform driver properly handles the specific ohci-au1xxx resume
from suspend case.
This also greatly simplifies the power_{on,off} callbacks and make them
work on platform device id instead of checking the OHCI controller base
address like what was done in ohci-au1xxx.c.
Impacted defconfigs are also updated accordingly to select the OHCI platform
driver.

Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols,
it's time to get rid of them: Move some of the platform devices to the
boards which can use them, Rename a few (unused) constants in the header,
Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally
delete them altogether from the Alchemy Kconfig file.

This patch removes the last hardcoded base address from the au1000_eth
driver. The base address of the MACDMA unit was derived from the
platform device id; if someone registered the MACs in inverse order
both would not work.
So instead pass the base address of the DMA unit to the driver with
the other platform resource information.

au1000_eth uses firmware calls to get a valid MAC address, and changes
it depending on platform device id. This patch moves this logic out of
the driver into the platform device registration part, where boards with
supported chips can use whatever firmware interface they need; the default
implementation maintains compatibility with existing, YAMON-based firmware.

Currently, the eth devices are probed in the inverse order, first
au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board,
this makes trouble:
# ifconfig|grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:50:C2:0C:30:01
eth1 Link encap:Ethernet HWaddr 66:22:01:80:38:10
A bogous ethernet hwaddr is assigned to the first device and
au1xxx_eth0_device is mapped to eth1, which even does not work
properly. With this patch, the problems are gone:
# ifconfig|grep HWaddr
eth0 Link encap:Ethernet HWaddr 66:22:11:32:38:10
eth1 Link encap:Ethernet HWaddr 66:22:11:32:38:11

Eliminate the sharing of IRQ names among the differenct Alchemy
variants. IRQ numbers need no longer be hidden behind a
CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy
code less reliant on a hardcoded subtype.
This patch also renames the GPIO irq number constants. It's really
an interrupt line, NOT a GPIO number!
Code which relied on certain irq numbers to have the same name
across all supported cpu subtypes is changed to determine current
cpu subtype at runtime; in some places this isn't possible so
a "compat" symbol is used.
Run-tested on DB1200.

New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000),
which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c.
Notable improvements:
- supports Db1000, DB/PB1100/1500/1550/1200.
- support for carddetect and statuschange IRQs.
- pcmcia socket mem/io/attr areas and irqs passed through
platform resource information.
- doesn't freeze system during card insertion/ejection like
the one it replaces.
- boardtype is automatically detected using BCSR ID register.
Run-tested on the DB1200.
