powerpc/zImage: Also check for stdout-path

2018-12-22T10:47:23+00:00

The /chosen/linux,stdout-path is "deprecated" in favour of /chosen/stdout-path so we should be checking for both. Signed-off-by: Oliver O'Halloran Signed-off-by: Michael Ellerman

powerpc/boot: Expose Kconfig symbols to wrapper

2018-10-13T11:21:25+00:00

Currently the wrapper is built without including anything in $(src)/include/, which means there are no CONFIG_ symbols defined. This means the platform specific serial drivers were never enabled. We now copy the definitions into the boot directory, so any C file can now include autoconf.h to depend on configuration options.

powerpc/boot: Remove support for Marvell MPSC serial controller

2018-06-03T14:39:22+00:00

There are no longer any platforms that use Marvell's MPSC serial controller so remove its driver. Signed-off-by: Mark Greer Signed-off-by: Michael Ellerman

powerpc/boot: Only build CPM code when necessary

2017-12-11T02:03:31+00:00

As far as I can tell CONFIG_CPM is the right symbol to use to conditionally compile the cpm-serial.c code. Signed-off-by: Michael Ellerman

powerpc/boot: Only build OPAL code when necessary

2017-12-11T02:03:30+00:00

Only build the OPAL console code in when necessary. This looks like it should use CONFIG_PPC_POWERNV, but because the opal-call.S code is 64-bit only, we must only build it when we're building the boot wrapper 64-bit. Signed-off-by: Michael Ellerman

powerpc/boot: Only build uartlite if XILINX_VIRTEX=y

2017-12-11T02:03:30+00:00

The serial code in uartlite.c only matches if we find one of two Xilinx (xlnx) nodes in the device tree, there's no need to build or link the code on other platforms. As far as I can tell CONFIG_XILINX_VIRTEX is the appropriate symbol to use to conditionally compile the code. Signed-off-by: Michael Ellerman

powerpc: conditionally compile platform-specific serial drivers

2017-08-31T04:26:48+00:00

mpsc.c and mpc52xx-psc.c are platform-specific serial drivers, and should be compiled for the respective platforms only. Signed-off-by: Hannes Reinecke Reviewed-by: Torsten Duwe Signed-off-by: Michael Ellerman

powerpc/boot: Add OPAL console to epapr wrappers

2016-07-05T13:58:54+00:00

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

2014-11-09T22:59:30+00:00

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

2009-02-11T05:00:09+00:00

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.
