* mci imx-esdhc: increase write timeoutSascha Hauer2012-09-291-1/+1
| | | | | | | | | | The timeout for wating for the bus to be idle is too short when the card does internal garbage collection. This was triggered with filling an SD card under Linux with /dev/urandom, then doing a saveenv under barebox afterwards. Linux has timeouts here up to 300ms. Use a second to be safe.

* miidev: fix 1G wrong detectionEric Bénard2012-09-141-24/+9
| | | | | | | | | | since 99e72c8bbdbdc690025a5868d831f1fe79ad56fc on an i.MX51 based board, I get : "phy0: Link is up - 1000/Full". It seems miidev tries to probe the PHY to early and gets 0x3ffff which leads to the wrong capabilities setting.

The id is always read in 8bit mode. An additional callback is needed to switch the nand controller into 16bit mode. This currently depends on a safe read_byte (always) and read_buf (for onfi-only flashes) callback. It has been tested on OMAP, but is not something that generally works. For this reason the existence of the set_buswidth callback is used to determine whether we are able to do autodetection or not. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - dev_ready is supposed to return whether the device is ready or not, not to poll until the device is ready. - dev_ready should return true for ready and false for not ready - waitpin polarity is not needed (at least the kernel does not have it) - wait_mon_mask must be 32bit. The code was unused since no board specified a wait pin, so no breakage included. This also removes the now unused timeout variable from platformdata.
