Soren Brinkmann 2de4752d69 ARM: zynq: Actually remove hotplug.c
Commit 'ARM: zynq: Remove hotplug.c'
(caf86a73ea) was supposed to remove
hotplug.c - but it didn't. It moved all content from
hotplug.c elsewhere and removed its entry from the Makefile, but missed
to actually remove the whole file. Remove it now.

Soren Brinkmann caf86a73ea ARM: zynq: Remove hotplug.c
The hotplug code contains only a single function, which is an SMP
function. Move that to platsmp.c where all other SMP runctions reside.
That allows removing hotplug.c and declaring the cpu_die function
static.

Michal Simek aa7eb2bb4e arm: zynq: Add smp support
Zynq is dual core Cortex A9 which starts always
at zero. Using simple trampoline ensure long jump
to secondary_startup code.

Arnd Bergmann 18cb63b3f3 ARM: zynq: remove incorrectly deleted file
My previous commit left the file empty and present in the
Makefile, which is a bit dirty and caused problems with
'make distclean', as pointed out by David Howells.
This hopefully cleans it up the right way.

John Linn b85a3ef4ac ARM: Xilinx: Adding Xilinx board support
The 1st board support is minimal to get a system up and running
on the Xilinx platform.

This platform reuses the clock implementation from plat-versatile, and
it depends entirely on CONFIG_OF support.  There is only one board
support file which obtains all device information from a device tree
dtb file which is passed to the kernel at boot time.
