2013-05-13blackfin: Move blackfin serial driver out of blackfin arch folder.Sonic Zhang
- Move blackfin serial driver to the generic driver folder. - Move blackfin serial headers to blackfin arch head folder. - Update the include path to blackfin serial header in start up code. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>
2013-05-13blackfin: Enable early print via the generic serial API.Sonic Zhang
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.

2013-05-13blackfin: Correct early serial mess output in BYPASS boot mode.Sonic Zhang
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. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>

2011-07-12Blackfin: serial: move early debug strings into .rodata sectionMike Frysinger
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). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: serial: convert to bfin_{read,write} helpersMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: uart: add multiple serial supportMike Frysinger
This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs. Ends up adding only ~512bytes per additional UART. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-07-13Blackfin: serial: convert to portmux frameworkMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
