mmc: sdhci: Avoid commands errors by simple timeout adaptation.
Old command timeout value was too small and it caused I/O errors which led to uncompleted read/write/erase operations and filesystem errors. Timeout adaptation fixes this issue. Changes in sdhci_send_command() function: - change timeout variable to static - increase default command timeout to 100 ms - add definition of max command timeout value, which can be redefined in each board config file - wait for card ready state for max defined time if it doesn't exceed defined maximum or return COMM_ERR Once successfully increased timeout value will be used in next function call. This fix was tested on Goni, Trats, Trats2 boards by testing UMS on MMC storage. Changes v2: - move global variable cmd_timeout into function sdhci_send_command() - change condition "==" to ">=" when comparing time with timeout - print information about timeout increasing and card busy timeout Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Pantelis Antoniou <panto@antoniou-consulting.com>
