powerpc/boot: Add OPAL console to epapr wrappers

2016-07-05T13:58:54Z

This patch adds an OPAL console backend to the powerpc boot wrapper so that decompression failures inside the wrapper can be reported to the user. This is important since it typically indicates data corruption in the firmware and other nasty things. Currently this only works when building a little endian kernel. When compiling a 64 bit BE kernel the wrapper is always build 32 bit to be compatible with some 32 bit firmwares. BE support will be added at a later date. Another limitation of this is that only the "raw" type of OPAL console is supported, however machines that provide a hvsi console also provide a raw console so this is not an issue in practice.

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] mv64x60: Fix FDT compatible names: mv64x60 => mv64360

2008-04-15T11:21:24Z

Compatible names should refer to a specific version of the hardware, without wildcards. Change each instance of mv64x60 to mv64360, which is the oldest version we currently support. Signed-off-by: Mark A. Greer Signed-off-by: Dale Farnsworth Signed-off-by: Paul Mackerras
