After commit 26b88520 ("mmc:

here stopped booting:

[    2.348602] LR is at trace_hardirqs_on_caller+0x15c/0x1b0

...

This turned out to be due to memory corruption caused by long-broken
PIO code in drivers/mmc/host/omap.c.  (Previously, this driver had
been using DMA; but the above commit caused the MMC driver to fall
back to PIO mode with an unmodified Kconfig.)

The PIO code, added with the rest of the driver in commit
730c9b7e ("[MMC] Add OMAP MMC host
driver"), confused bytes with 16-bit words.  This bug caused memory
located after the PIO transfer buffer to be corrupted with transfers
larger than 32 bytes.  The driver also did not increment the buffer
pointer after the transfer occurred.  This bug resulted in data
corruption during any transfer larger than 64 bytes.

For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim.  For these specific MoviNAND devices, we skip
these operations.

Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.

The documentation for the dw_mmc part says that the low power
mode should normally only be set for MMC and SD memory and should
be turned off for SDIO cards that need interrupts detected.

The best place I could find to do this is when the SDIO interrupt
was first enabled.  I rely on the fact that dw_mci_setup_bus()
will be called when it's time to reenable.

Data transfer will be continued until all the bytes are transmitted,
even if data crc error occurs during a multiple-block data transfer.
This means RXDR/TXDR interrupts will occurs until data transfer is
terminated. Early setting of host->sg to NULL prevents going into
xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts
occurs. And checking error interrupt status in the xxx_data_pio functions
is no need because dw_mci_interrupt does do the same. This patch also
removes it.

RINTSTS status includes masked interrupts as well as unmasked.
data_status and cmd_status are set by value of RINTSTS in interrupt handler
and tasklet finally uses it to decide whether error is happened or not.
In addition, MINTSTS status is used for setting data_status in PIO.
Masked error interrupt will not be handled and that status can be considered
non-error case.

Even if the datasheet says that the not busy flag has to be used only
for write operations, it's false except for version lesser than v2xx.

Not waiting on the not busy flag for read operations can cause the
controller to hang-up during the initialization of some SD cards
with DMA after the first CMD6 -- the next command is sent too early.

Pull OLPC platform updates from Andres Salomon:
 "These move the OLPC Embedded Controller driver out of
  arch/x86/platform and into drivers/platform/olpc.

  OLPC machines are now ARM-based (which means lots of x86 and ARM
  changes), but are typically pretty self-contained..  so it makes more
  sense to go through a separate OLPC tree after getting the appropriate
  review/ACKs."

  x86: OLPC: move s/r-related EC cmds to EC driver

  Platform: OLPC: turn EC driver into a platform_driver

  Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

Pull arm-soc Marvell Orion device-tree updates from Olof Johansson:
 "This contains a set of device-tree conversions for Marvell Orion
  platforms that were staged early but took a few tries to get the
  branch into a format where it was suitable for us to pick up.

  Given that most people working on these platforms are hobbyists with
  limited time, we were a bit more flexible with merging it even though
  it came in late."

Pull arm-soc cpuidle enablement for OMAP from Olof Johansson:
 "Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree,
  but didn't go in because the pull request ended up rejected.  So it
  just got merged, and we got this staged branch that enables the
  coupled cpuidle code on OMAP.

  With a stable git workflow from the other maintainer we could have
  staged this earlier, but that wasn't the case so we have had to merge
  it late.

  The alternative is to hold it off until 3.7 but given that the code is
  well-isolated to OMAP and they are eager to see it go in, I didn't
  push back hard in that direction."
