2014-10-15	uart: Works better if we actually allocate out_buf	Benjamin Herrenschmidt	1	-0/+1
	That got lost during a rebase ... oops. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-10-15	uart: Fix thinko in output ring pointers	Benjamin Herrenschmidt	1	-2/+2
	I accidentally typed uint8_t instead of uint32_t... thanks Joel. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-10-15	uart: Use prlog instead of printf	Benjamin Herrenschmidt	1	-4/+4
	And use PR_DEBUG for everything Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-10-15	uart: Keep synchronous console flush when IRQ not working	Benjamin Herrenschmidt	1	-3/+25
	Some boards are missing an EC for interrupts (or might not have the FPGA properly flashed). In that case the serial interrupt isn't working. We attempt to detect this by enabling all interrupts by default and when the first one occurs, we mark interrupts as "functional". Until they are detected as such, we keep all output flushes fully synchronous. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-10-15	uart: Add interrupt driver output ring buffer for Linux ouput	Benjamin Herrenschmidt	1	-41/+85

2014-10-15	uart: Give UART it's own OPAL console callbacks instead of dummy console	Benjamin Herrenschmidt	1	-100/+204
	This means the Linux output no longer gets into our internal log, which makes dumping of it from Linux a lot nicer. It will also allow us to improve the way we do the bufferring for Linux and to exploit eventually the TX interrupts. It will also allow us to implement some form of timeouts for the OPAL console variant of it so we don't get stuck of the BMC doesn't consume from the virtual UART.

2014-10-09	uart: Exploit Tx FIFO	Benjamin Herrenschmidt	1	-10/+18
	When THRE is 1, we can write up to 16 bytes, so let's make good use of it Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-07-02	Initial commit of Open Source release	Benjamin Herrenschmidt	1	-0/+343
