CM-X300 bootloader passes DRAM configuration information in ATAGS,
however, the first memory bank is reported at actual physical address 0x8000000.
Use the configuration information supplied by the bootloader and
cope with the necessity to have PHYS_ADDR=0xa0000000.

The previous definitions of SSCR0_SCR and SSCR0_SerClkDiv() prevented
them being used simultaneously when supporting multiple PXA SoCs, esp.
in drivers/spi/pxa2xx_spi.c, make them correct.
The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result
a little bit different in pxa2xx_spi_probe(), however, since that's only
used as a default initialization value, it's acceptable.

The corgi touchscreen is now deprecated in favour of the generic ads7846.c
driver. The noise reduction technique used in corgi_ts.c, which is to wait
till vsync before ADC sampling, is also integrated into ads7846 driver now.
Provided that the original driver is not generic and is difficult to maintain,
it will be removed now.

commit 672917dcc7 ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.
Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis. The fix is
simple, zero the variable after doing the work from the previous idle.
During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.

Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down. Device failure/removal
etc are still recorded on spares.
However commit 51d5668cb2 broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:
This means that the alignment between 'odd/even' and
'clean/dirty' might take a little longer to attain,
how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.
So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately. There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update). We just piggy-back on that.
