| * | | mci: core: Increase clock for SD highspeed modeSascha Hauer2015-10-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Putting a SD card into highspeed mode doesn't help much when we still clock the card with 25MHz. Increase the clock speed to 50MHz for high speed cards. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. The 'index' of ehci_submit_root() is not always > 0. e.g. While it gets invoked from usb_get_descriptor(), the 'index' is always a '0'. (See ch.9 of USB2.0) 2. The PORTSC register is not always required, and thus it should only report a port error when necessary. It would cause a port scan failure if the ehci_submit_root() always gets terminated by a port error.

This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of writing one word to the txfifo and then wait until one is received in the rxfifo we can write until the txfifos are not full and read as long the rxfifos contain data.

First of all the algorithm doesn't work properly. SPI NOR flashes can only protect a certain amount of blocks from the end of the device which is incompatible to the protect(start,len) API we have. The algorithm tries to be clever by doing protection only when it does not protect unrelated blocks and unprotection only when it does not unprotect unrelated blocks. This breaks for example when some code protects the last blocks (which may contain the bootloader), then protects the blocks before the last ones (which may contain the environment). Then if we try to overwrite the bootloader this won't work since it would unprotect the environment aswell, so the driver will not unprotect anything resulting in a failed erase/write later. Then the protection behaviour is different between different flashes. Some have three protection bits, some have four. For some the smallest protection are is 1/16 of the device, others have 1/256 or 1/64. Some have a bit which selects the lower area instead of upper area for protection. The position of this bit differs on different flashes. This patch removes the lock code completely and always unprotects the whole device. This way we can unprotect a device for writing to it and never protect it again. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
