It makes no sense that some Freescale device tree files are in fsl directory while some others not. This patch move Freescale device tree files into fsl folder. To do that the following two steps are made: - Move Freescale device tree files into fsl folder. - Update the include path in these files from "fsl/*.dtsi" to "*.dtsi".

While the handling of fsl,pq3-gpio and fsl,mpc8572-gpio is done in the same driver and the two hardly differ, the latter controller needs a workaround for an erratum in the gpio_get callback.

2015-10-15powerpc: Delete old orphaned PrPMC 280/2800 DTS and boot file.Paul Gortmaker2-868/+0
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.

2015-08-18powerpc: Add a vga alias node for P1022Jason Jin2-1/+3
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.

2015-04-07powerpc: Remove the celleb supportMichael Ellerman1-2/+0
The celleb code has seen no actual development for ~7 years. We (maintainers) have no access to test hardware, and it is highly likely the code has bit-rotted. As far as we're aware the hardware was never widely available, and is certainly no longer available, and no one on the list has shown any interest in it over the years. So remove it. If anyone has one and cares please speak up. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Jeremy Kerr <jk@ozlabs.org>

2015-03-16powerpc/boot: don't clobber r6 and r7 in epapr bootJeremy Kerr1-12/+12
We use r6 and r7 for epapr boot, but the current pre-C init will clobber both of these. This change does a simple replacement, of r6 -> r12 and r7 -> r13, so that we hit platform init with these registers intact.

2015-03-16powerpc/boot: Fix stack corruption in epapr entry pointJeremy Kerr1-1/+1
Currently, a 64-bit little-endian zImage.epapr won't boot in epapr mode, as we never return from platform_init. Before entering C, we initialise our stack by setting r1 16 bytes below the end of the _bss_stack: stwu r0,-16(r1) /* establish a stack frame */ However, the called function will save the caller's lr in the caller's frame's lr save area, at -16(r1) to -32(r1). This means that writes to the fdt variable will corrupt the saved link register: 0000000020c06018 l O .bss 0000000000001000 _bss_stack 0000000020c07018 l O .bss 0000000000000008 fdt We'll need at least 32 bytes in the initial stack frame, to handle the LR save area. We bump this to 112 bytes, as that'll be the max required by ABIv1. Thanks to Alistair Popple for debugging help.

2015-03-16powerpc/boot/wrapper: use the pseries wrapper for zImage.epaprJeremy Kerr1-1/+1
We'll likely be entering the zImage.epapr as BE, so include the pseries implementation of _zimage_start, which adds the endian fixup magic. Although the endian fixup won't work on Book III-E machines starting LE, the current entry point doesn't support LE anyway, so we shouldn't be breaking anything.
