| * mmc: Tegra: Fix timeout issue seen on certain eMMC partsMarcel Ziswiler2014-10-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During rigorous testing of our latest update infrastructure I came across quite consistent timeouts on certain eMMC parts (e.g. Hynix H26M21001ECR) when writing big (e.g. in excess of 400 MB) file system images: MMC write: dev # 0, block # 40960, count 944128 ... mmc_send_cmd_bounced: MMC Timeout Interrupt status 0x00000001 Interrupt status enable 0xdfff003b Interrupt signal enable 0xdfff0002 Present status 0x01870106 mmc write failed Comparing the various data sheets I came across the following timeout specification: Secure Erase/TRIM Timeout=300ms*2*10=6000ms Unfortunately empirical testing still failed albeit much more rarely. Increasing the timeout to 8000ms made it finally disappear entirely. This patch allows us writing various eMMC parts without seeing any further issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adjust the driver so that leaf functions take a pointer to the serial port register base. Put all the global configuration in the init function, and use the same settings from then on. This makes it much easier to move to driver model without duplicating the code, since with driver model we use platform data rather than global settings. The driver is compiled with either the CONFIG_PL010_SERIAL or CONFIG_PL011_SERIAL option and this determines the uart type. With driver model this needs to come in from platform data, so create a new CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the driver to support both peripheral variants.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want the SPI flash probing feature to operate as a standard driver. Add a driver for the basic probing feature used by most boards. This will be activated by device_probe() as with any other driver. The 'sf probe' command currently keeps track of the SPI slave that it last used. This doesn't work with driver model, since some other driver or system may have probed the device and have access to it too. On the other hand, if we try to probe a device twice the second probe is a nop with driver model. Fix this by searching for the matching device, removing it, and then probing it again. This should work as expected regardless of other device activity. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
