blackfin: Enable early print via the generic serial API.

2013-05-13T08:26:27+00:00

Remove blackfin specific implementation of the generic serial API when
early print macro is defined.

In BFIN_BOOT_BYPASS mode, don't call generic serial_puts, because
early print in bypass mode is running before code binary is relocated
to the link address.

blackfin: Correct early serial mess output in BYPASS boot mode.

2013-05-13T07:47:24+00:00

The early serial should not be configured again in initcode() for BYPASS
boot mode and in start() for the other LDR boot modes.

In BYPASS boot mode, the start up code is located in Nor flash address other
than the DRAM address defined in link script. The code embedded string can't
be addressed by its compile time symbol. Calculate it according to the flash
offset.

Blackfin: serial: move early debug strings into .rodata section

2011-07-12T06:17:46+00:00

Rewrite the assembly serial_early_puts() helper to place the strings
in the .rodata section rather than embedding them directly in the
.text section.  Using .text is a little simpler, but it doesn't let
people execute out of internal L1 sram (since core reads don't work
on those regions).

Blackfin: serial: convert to bfin_{read,write} helpers

2011-07-12T06:17:46+00:00

Since the serial struct declares the sizes for us, no need to hardcode
them in the accessor functions.  Let the bfin_{read,write} helpers do
it for us.

Blackfin: uart: add multiple serial support

2011-07-12T06:17:45+00:00

This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs.
Ends up adding only ~512bytes per additional UART.

Blackfin: serial: convert to portmux framework

2010-07-13T21:50:50+00:00

Use the new portmux framework to handle the details when possible.
Unfortunately, we cannot yet use this in the standalone initialization
logic, so we need to keep around the old portmux writes for now.
