2016-07-05powerpc/boot: Add OPAL console to epapr wrappersOliver O'Halloran
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.

2015-12-09powerpc/sbc8641: drop bogus PHY IRQ entries from DTS filePaul Gortmaker
This file was originally cloned off of the MPC8641D-HPCN reference platform, which actually had a PHY IRQ line connected. However this board does not. The bogus entry was largely inert and went undetected until commit 321beec5047af83db90c88114b7e664b156f49fe ("net: phy: Use interrupts when available in NOLINK state") was added to the tree. With the above commit, the board fails to NFS boot since it sits waiting for a PHY IRQ event that of course never arrives. Removing the bogus entries from the DTS file fixes the issue.

In commit 3c8464a9b12bf83807b6e2c896d7e7b633e1cae7 ("powerpc: Delete old PrPMC 280/2800 support") we got rid of most of the C code, and the Makefile/Kconfig hooks, but it seems I left the platform's DTS file orphaned in the tree as well as the boot code. Here we get rid of them both.

The kernel does it, not the boot wrapper, which breaks with some cross compilers that still default to ABI v1.

2015-08-17powerpc: Add a vga alias node for P1022Jason Jin
In u-boot, when set the video as console, the name 'vga' is used as a general name for the video device, during the fdt_fixup_stdout process, the 'vga' name is used to search in the dtb to setup the 'linux,stdout-path' node. Though the P1022 DIU is not VGA-compatible device, to meet the 'vga' name used in u-boot, the vga alias node is added for P1022 in this patch. At the same time, a display alias is also added so that no other components grow dependencies on the vga alias node.
