How significant is the cache maintenance over head?
It depends, the eMMC are much faster now
compared to a few years ago and cache maintenance cost more due to
multiple cache levels and speculative cache pre-fetch. In relation the
cost for handling the caches have increased and is now a bottle
pre_req() runs dma_map_sg(), post_req() runs dma_unmap_sg.
If not calling pre_req() before omap_hsmmc_request()
dma_map_sg will be issued before starting the transfer.
It is optional to use pre_req(). If issuing pre_req()
post_req() must be to be called as well.

Previously there has only been one function mmc_wait_for_req()
to start and wait for a request. This patch adds

If there is on ongoing request wait for completion
of that request and start the new one and return.

Add an additional mmc queue request instance to make way for
two active block requests. One request may be active while the
other request is being prepared.

Break out code from mmc_blk_issue_rw_rq to create a
block request prepare function. This doesn't change
any functionallity. This helps when handling more
than one active block request.

This simple fault injection proved to be very useful to
test the error handling in the block.c rw_rq(). It may
still be useful to test if the host driver handle
pre_req() and post_req() correctly in case of errors.

Change mmc_blk_issue_rw_rq() to become asynchronous.
The execution flow looks like this:
The mmc-queue calls issue_rw_rq(), which sends the request
to the host and returns back to the mmc-queue. The mmc-queue calls
issue_rw_rq() again with a new request. This new request is prepared,

I've started on some basic documentation for LAVA at

This is mostly aimed at those who are trying to set it up for themselves, or
get started on development for it. However I'm also starting to cover
example jobs, and will expand that

Hi John,
These are the patches not yet merged upstream, but are required
for a good enabling of u-boot on i.MX53 QuickStart board. Please
consider pull.

Efika: fix build breakage (2011-06-22 20:04:02 -0600)
DA9052 PMIC has capability to supply power for upto 3 banks of 6 white serial
LEDS. It can also control intensity of independent banks. To drive these
banks boost converter will provide up to 24V and forward current of max. 50mA.
This patch controls intensity of the individual WLEDs bank through
The DA9052 PMIC provides an Analogue to Digital Converter with 10 bits
resolution and 10 channels.
This patch montiors the DA9052 PMIC's ADC channels mostly for battery parameters
like battery temperature, junction temperature, battery current etc.

I have done some benchmarking on OMAP4 running Ubuntu for various versions

In preparation for the release of Linaro 11.06 images on 2011-06-30,
a suitable candidate has been selected for testing. The release is
expected to be tested heavily and provide the most stable and
feature-rich images to date this cycle.
