| | | | | | | | | | | | | This patch provides support to set the quad enable bit on flash. quad enable bit needs to set before performing any quad IO operations on respective SPI flashes. Currently added set quad enable bit for winbond and spansion flash devices. stmicro flash doesn't require to set as qeb is volatile. remaining flash devices support will add in future patches.

* spi: Add Faraday SPI controller supportKuo-Jung Su2014-01-11-0/+509
| | | | | | | | | | | | | | | | | The Faraday FTSSP010 is a multi-function controller which supports I2S/SPI/SSP/AC97/SPDIF. However This patch implements only the SPI mode. NOTE: The DMA and CS/Clock control logic has been altered since hardware revision 1.19.0. So this patch would first detects the revision id of the underlying chip, and then switch to the corresponding software control routines.

During measurements at our lab we found that some cards implementing this feature having really strong driver strengts per default. This can lead to voltage peaks above the specification of the host on signal edges for data sent from a card to the host. Since availability of a given card type may be shorter than the time a certain hardware will be produced it is useful to have support for this command (Alternative would be changing termination resistors and adapting the driver strength of the host to the used card.) Following proposal for an implementation: - new field that reflects CSD field DSR_IMP in struct mmc - new field for design specific DSR value in struct mmc - board code can set DSR value in mmc struct just after registering an controller - mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set Additionally the mmc command is extended to make is possible to play around with different DSR values. The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after calling fsl_esdhc_initialize() for the eMMC.

The memcpy_16() function will treat the buffer as an array of "unsigned short", thus triggering unaligned access if the compiler decided ffchars[] to be not aligned.

It seems that earlier HW may have cleared this bit autonomously when starting a new transfer, and hence this code was not needed in practice. However, this is generally a good idea in all cases. In Tegra124, the HW behaviour appears to have changed, and SW must explicitly clear this bit. Otherwise, SW will believe that transfers have completed when they have not, and may e.g. read stale data from the RX FIFO.

This is related to the way nand_scan_tail() handles assigning functions to ecc ops: If we are switching to software ecc/no ecc, it assigns default functions to the ecc ops pointers unconditionally, but if we are switching to hardware ecc, the default hardware ecc functions are assigned to ops pointers only if these pointers are NULL (so that drivers could set their own functions). In the case of omap_gpmc.c driver, when we switch to sw ecc, sw ecc functions are assigned to ecc ops by nand_scan_tail(), and when we later switch to hw ecc, the ecc ops pointers are not NULL, so nand_scan_tail() does not overwrite them with hw ecc functions. The result: sw ecc functions used to write hw ecc data. Clear the ecc ops pointers in omap_gpmc.c when switching ecc types, so that ops which were not assigned by the driver will get the correct default values from nand_scan_tail().

This is done under the assumption that the struct exists only to store values, so it is OK to overwrite it, but there is at least one situation where this assumption is incorrect: When switching to 1 bit hamming code sw ecc, the job of assigning layout data is outsourced to nand_scan_tail(), which simply assigns into ecc.layout a pointer to an existing struct prefilled with the appropriate values. This struct doubles as both data and layout definition, and therefore shouldn't be overwritten, but on the next switch to hardware ecc, this is exactly what's going to happen. The next time the user switches to software ecc, they're going to get a messed up ecc layout. Prevent this and possible similar bugs by explicitly using the private-to-omap_gpmc.c omap_ecclayout struct when switching ecc mode.

Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert to the original behavior.

As the control structure will not be filled, we will produce a null ptr dereference if the controller is not inited. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Simon Glass <sjg@chromium.org>

Here the timeout is increased when we fill up the whole buffer. This delay allows eMMC memory to perform its internal operations. Otherwise we end up with HOST's error regarding GET_STATUS receive timeout. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
