* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

* input: i8042: Provide feature to disable keyboard before booting kernelLouis Yung-Chieh Lo2012-10-19-0/+13
| | | | | | | | | | | | | | | | The BIOS leaves the keyboard enabled during boot time so that any keystroke would interfere kernel driver initialization. Add a way to disable the keyboard to make sure no scancode will be generated during the boot time. Note that the keyboard will be re-enabled again after the kernel driver is up. This code can be called from the board functions.

* input: Use finer grain udelays while waitng for the i8042 keyboard buffer to ā†µGabe Black2012-10-19-0/+6
| | | | | | | | | | | | | | | | | | | | | empty On x86, the i8042 keyboard controller driver frequently waits for the keyboard input buffer to be empty to make sure the controller has had a chance to process the data it was given. The way the delay loop was structured, if the controller hadn't cleared the corresponding status bit immediately, it would wait 1ms before checking again. If the keyboard responded quickly but not instantly, the driver would still wait a full 1ms when perhaps 1us would have been sufficient. Because udelay is a busy wait anyway, this change decreases the delay between checks to 1us. Also, this change gets rid of a hardcoded 250ms delay. On Stumpy, this saves 100-150ms during boot.
