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.

'Wait for Interrupt' mode be entered right after disabling the processor clock

Furthermore, get rid of the #ifndef CONFIG_DEBUG_KERNEL, since arch_idle()

1d5b4c0fa9 ARM: 6406/1: at91sam9g45: fix i2c bus speed
Use a correct udelay value to get bus speed around 100KHz. The udelay
value was most likely copied from the older devices, but the 9g45
is signicantly faster (400MHz, DDR, ..), so a udelay of 2 gives a
bus speed of around 190KHz, which is too fast for some devices.
A udelay value of 5 gives a bus speed of around 90KHz here.

64d72bbeeb AT91: at91sam9261ek board: remove warnings related to use of SPI or SD/MMC
The sd/mmc data structure is not used if SPI is selected. The configuration
of PIO on the board prevent from using both interfaces at the same time
(board dependent).
Remove the warnings at compilation time adding a preprocessor condition.

ab64511cbb AT91: SAM9G45 - add a separate clock entry for every single TC block
Without this patch you will not be able to register the first block
because of the second association call on at91_add_device_tc().

5afddee415 AT91: clock: peripheral clocks can have other parent than mck
While registering clock allow to set parent clock other
than mck. It is useful for clocks than can be seen as
child clock of a peripheral.
