* powerpc: Introduce a new config symbol to control 16550 early debug codePaul Mackerras2006-01-10
| | | | | | | | | | The previous change by Kumar Gala in this area led to legacy_serial.c and udbg_16550.c being built as modules when CONFIG_SERIAL_8250=m. Fix this by introducing a new symbol, CONFIG_PPC_UDBG_16550, to control whether these files get built, and arrange for it to be selected for those platforms that need it.

* [PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | This moves the discovery of legacy serial ports to a separate file, makes it common to ppc32 and ppc64, and reworks it to use the new OF address translators to get to the ports early. This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.

* powerpc: Move a bunch of ppc64 headers to include/asm-powerpcPaul Mackerras2005-11-14
... and also delete some that are no longer used because we already had an include/asm-powerpc version of the header. Signed-off-by: Paul Mackerras <paulus@samba.org>
