568aa7508c ARM: at91: AT91CAP9 has a macb device
commit

	ee621dd (net: atmel_macb Kconfig: remove long dependency line)

replaced a list of several explicit machines in the dependencies of MACB by
a single symbol that is selected by the respective machines. ee621dd missed
to let ARCH_AT91CAP9 select HAVE_NET_MACB though which is fixed here.

a2255ff451 mmc: at91_mci: fix multiblock SDIO transfers
The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte
transfers, but at91_mci driver doesn't use them and handles all SDIO
transfers as ordinary MMC block transfers. This causes problems for
multiple-block SDIO transfers (in particular for 256-bytes blocks).

Fix this situation by checking the opcode for SDIO CMD53 and setting
the transfer type in the AT91_MCI_CMDR register properly.

This patch was tested with libertas SDIO driver: problem with TX
timeouts on big packets was eliminated.

0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

5c189208b6 ARM: 6436/1: AT91: Fix power-saving in idle-mode on 926T processors
According to Atmel, their 926T processors (AT91 post RM9200) requires
'Wait for Interrupt' mode be entered right after disabling the processor clock
in order to minimise current consumption when idle, so do both provided we're
not running on a 920T (an RM9200).

Furthermore, get rid of the #ifndef CONFIG_DEBUG_KERNEL, since arch_idle()
can be turned off completely with the kernel parameter 'nohlt'.
