Blackfin: avoid get_sclk() with early serial debug

2009-05-06T12:47:27Z

When the clock functions were changed to use cached values (and thereby avoiding expensive math functions), early serial debug broke because the baud programming is called before external memory is available. Signed-off-by: Mike Frysinger

Blackfin: audit UART for all known anomalies

2009-04-06T21:37:49Z

There is no code change here, just new comments, but this keeps me from having to do another audit from scratch in the future. Signed-off-by: Mike Frysinger

Blackfin: dynamically update UART speed when initializing

2009-02-06T02:25:35Z

Previously, booting over the UART required the baud rate to be known ahead of time. Using a bit of tricky simple math, we can calculate the new board rate based on the old divisors. Signed-off-by: Mike Frysinger Signed-off-by: Robin Getz

Blackfin: allow serial console to be disabled

2009-01-28T18:26:15Z

Some devices have no UART device pulled out, so allow people to disable the driver completely in favor of other methods (like JTAG-console). Signed-off-by: Mike Frysinger

Blackfin: add portmuxing for UARTs on the BF51x

Blackfin: make baud calculation more accurate

2008-10-23T09:03:51Z

We should use the algorithm in the Linux kernel so that the UART divisor calculation is more accurate. It also fixes problems on some picky UARTs that have sampling anomalies. Signed-off-by: Mike Frysinger

Blackfin: unify cpu and boot modes

2008-03-30T19:50:19Z

All of the duplicated code for Blackfin processors and boot modes have been unified. After all, the core is the same for all processors, just the peripheral set differs (which gets handled in the drivers). Signed-off-by: Mike Frysinger
