sdhci: support JMicron JMB38x chips

2007-12-12T19:01:00+00:00

The JMicron JMB38x chip doesn't support transfers that aren't 32-bit
aligned (both size and start address). It also doesn't like switching
between PIO and DMA mode, so it needs to be reset after each request.

sdhci: use PIO when DMA can't satisfy the request

2007-12-12T19:01:00+00:00

Some controllers have been designed on the assumption that all transfers
will be 32-bit aligned, both in start address and in size. This is not a
guarantee the SDHCI specification provides and not one we can provide.

Revert back to PIO for individual requests in order to work around the
hardware bug.

sdhci: don't warn about sdhci 2.0 controllers

2007-12-12T19:01:00+00:00

We support 2.0 controllers, even though we don't use anything in the new
feature set.

spi: use simplified spi_sync() calling convention

2007-12-05T17:21:19+00:00

Given the patch which simplifies the spi_sync calling convention, this one
updates the callers of that routine which tried using it according to the
previous specification.  (Most didn't.)

sdio_uart: fix sign of paramter status in sdio_uart_receive_chars()

2007-11-29T18:10:30+00:00

This also fixes a sparse warning about different signedness.
Only compile tested, because i do not have the hardware.

mmc: Add missing sg_init_table() call

2007-11-27T08:19:40+00:00

mmc_init_queue only initializes the scatterlists with sg_init_table()
when using a bounce buffer. This leads to a BUG() when CONFIG_DEBUG_SG
is set.

mmc: Avoid re-using minor numbers before the original device is closed.

2007-11-21T17:45:38+00:00

Move the code which marks the minor number as free to mmc_blk_put() so
that it happens on the final close() (or removal), instead of doing it
at removal even when the device is still logically open.

tifm_sd: handle non-power-of-2 block sizes

2007-11-21T17:42:45+00:00

It is possible to handle arbitrary block sizes with tifm card reader by
conditionally switching to PIO in case such block has to be delivered. At
the beginning of each request, DMA is either disabled (non-power-of-2 block
size) or set to load time user preference.

mmc_block: check card state after write

2007-11-21T17:40:53+00:00

Some cards have been reported to signal that they're ready prematurely.
Checking both the busy bit and card state solves the issue.
