Subject: MMC updates for 2.6.40-rc1
Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc.git for-linus
to receive the MMC merge for 2.6.40-rc1. There are currently no merge
conflicts, and the patches have been tested in linux-next. Thanks.
Highlights are:
Core:
* eMMC 4.4 "boot partition" support. This exposes an eMMC device's
boot partitions, which are accessed separately from the other
partitions as (e.g.) /dev/mmcblk0boot0. There's a strong potential
for bricking the device you're running on by writing to these (they
are usually used by the bootloader), so we disable write access by
default. To write to them, first perform:
# echo 0 > /sys/block/mmcblkXbootY/force_ro
* An ioctl for running MMC CMD/ACMDs from userspace (with CAP_SYS_RAWIO).
This is primarily useful for enabling built-in security functionality
on SD cards.
* A new per-*card* quirks mechanism, along with two cases where this is
necessary: one where some Sandisk cards handle erase/trim arguments
differently, and one where the same optimization (CMD23 multiblock
transfers) causes a large (50%, for some tests) performance increase
on SanDisk cards and a small performance *decrease* on others.
* Reliable write support for MMC cards, servicing REQ_FUA/REQ_META
requests.
* eMMC Dual Data Rate support.
Drivers:
* SD v3.0 improvements, with support for SDXC cards at ultra-high-speed
(up to 104MB/sec) modes. Thanks to Arindam Nath at AMD for this
patchset, also Andrei Warkentin at Motorola and Philip Rakity at
Marvell.
* New "vub300" driver for Elan Digital Systems' VUB300 chip, which is
a USB connected SDIO/SD/MMC host controller.
* tmio_mmc, sh_mmcif: Runtime and system-wide suspend support.
