* spi: mxc: fix sf probe when using mxc_spiNikita Kiryanov2014-09-24-33/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MXC SPI driver has a feature whereas a GPIO line can be used to force CS high across multiple transactions. This is set up by embedding the GPIO information in the CS value: cs = (cs | gpio << 8) This merge of cs and gpio data into one value breaks the sf probe command: if the use of gpio is required, invoking "sf probe <cs>" will not work, because the CS argument doesn't have the GPIO information in it. Instead, the user must use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must type "sf probe 15872". This is inconsistent with the description of the sf probe command, and forces the user to be aware of implementaiton details. Fix this by introducing a new board function: board_spi_cs_gpio(), which will accept a naked CS value, and provide the driver with the relevant GPIO, if one is necessary.

| * dm: avoid dev->req_seq overflowRobert Baldyga2014-09-23-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Since dev->req_seq value is initialized from "reg" property of fdt node, there is posibility, that address value contained in fdt is greater than INT_MAX, and then value in dev->req_seq is negative which led to probe() fail. This patch fix this problem by ensuring that req_seq is positive, unless it's one of errno codes. Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>

In order to clear the RDRF flag we only need to read the data register. Also, when stressing U-Boot a lot with serial input, an overflow can occur which asserts the S1_OR flag (while not asserting the S1_RDRF flag). To clear this flag we again just need to read the data register, hence add this flag to the abort conditions for the while loop. Insert a compiler barrier to make sure reading the data register gets executed after reading the status register. Signed-off-by: Stefan Agner <stefan@agner.ch>
