* mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou2013-05-06-32/+105
| | | | | | | | | | | | | | | | | | | Most of time that MMC driver spends on initializing a device is polling OCR (operation conditions register). To decouple this polling loop, device init is split into two parts: The first part fires the OCR query command, and the second part polls the result. So the caller is now no longer bound to the OCR-polling delay; he may fire the query, go somewhere and then come back later for the result. To use this, call mmc_set_preinit() on any device which needs this. This can save significant amounts of time on boot (e.g. 200ms) by hiding the MMC init time behind other init.

Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function.

For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg (ECSPIx_CONGREG) the i.MX6 technical reference manual states: -- cut -- ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block and resets the internal logic with the exception of the ECSPI_CONREG. -- cut -- Note the exception mentioned: The CONREG itself isn't reset. Fix this by manually writing the reset value 0 to the whole register. This sets the EN bit to zero, too (i.e. includes the old ~MXC_CSPICTRL_EN). 2. We want to reset the whole SPI block here. So it makes no sense to first read the old value of the CONREG and write it back, later. This will give us the old (historic/random) value of the CONREG back. And doesn't reset the CONREG. To get a clean CONREG after the reset of the block, too, don't use the old (historic/random) value of the CONREG while doing the reset. And read the clean CONREG after the reset. This was found while working on a SPI boot device where the i.MX6 boot ROM has already initialized the SPI block. The initialization by the boot ROM might be different to what the U-Boot driver wants to configure. I.e. we need a clean reset of SPI block, including the CONREG.

In case where both host controller and card support 8bit transfers, they agree to communicate on 8bit interface while some boards support only 4bit interface. Due to this reason the mmc 8bit default mode fails on these boards. To rectify this, define maximum bus width supported by these boards (4bit). If max_bus_width is not defined, it is 0 by default and 8bit width support will be enabled in host capabilities otherwise host capabilities are modified accordingly. It is tested with a MMCplus card.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently, CONFIG_SYS_HZ must be 1000. Change this, and fix the timer driver to conform to this. Have the timer implementation export a custom API get_timer_us() for use by the BCM2835 MMC API, which needs us resolution for a HW workaround. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
