powerpc/boot: Parse chosen/cmdline-timeout parameter

2014-11-09T22:59:30Z

On some platforms a 5 second timeout during boot might be quite long, so make it configurable. Run the loop at least once to let the user stop the boot by holding a key pressed. If the timeout is set to 0, don't wait for input, which can be used as a workaround if the boot hangs on random data coming in on the serial port.

powerpc/amigaone: Bootwrapper and serial console support for AmigaOne

2009-02-11T05:00:09Z

This adds the bootwrapper for the cuImage target and a compatible property check for "pnpPNP,501" to the generic serial console support code. The default link address for the cuImage target is set to 0x800000. This allows to boot the kernel with AmigaOS4's second level bootloader, which always loads a uImage at 0x500000.

[POWERPC] bootwrapper: serial_console_init() fixes

2007-08-22T05:21:48Z

1. Search the entire compatible list for serial devices. The serial code previously did a simple strcmp on the compatible node; this fails when the match string is not the first compatible listed. Use dt_is_compatible() instead. 2. Don't call serial_edit_cmdline if getc isn't defined. Signed-off-by: Scott Wood Acked-by: David Gibson Signed-off-by: Paul Mackerras
