Michal Simek 8fff2f752f ARM: zynq: Move early printk virtual address to vmalloc area
The patch
"ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000"
(sha1: 6ff0966052)
has moved also start of VMALLOC area because size didn't change.
That's why origin location of vmalloc was
   vmalloc : 0xf0000000 - 0xff000000   ( 240 MB)
and now is
   vmalloc : 0xf0800000 - 0xff800000   ( 240 MB)

That's why uart virtual addresses need to be changed to reflect this new
memory setup. Starting address should be vmalloc start address.

Arun Chandran 974a2aba99 ARM: zynq: Fix earlyprintk in big endian mode
earlyprintk messages are not appearing on the terminal
emulator during a big endian kernel boot. In BE mode
sending full words to UART will result in unprintable
characters as they are byte swapped versions of printable
ones. So send only bytes.

Michal Simek eb28d0bb85 ARM: zynq: Enable big-endian
Enable ARCH_SUPPORTS_BIG_ENDIAN in Kconfig.

zynq_secondary_trampoline is the first function
that is called on secondary CPU.
Reference:
"ARM: mcpm: fix big endian issue in mcpm startup code"
(sha1: 519ceb9fd1)

Fix early printk support. Based on:
"ARM: pl01x debug code endian fix"

Michal Simek 90a6695a2a ARM: zynq: Fix uart0 early console virtual address
Virtual address have to have the same offset within
a 2MB aligned section of virtual/phycial address space.

Fix uart0 virtual address to be align with physical one.
Also remove UART_SIZE which is completely unused.

Josh Cartwright 9a45eb691d ARM: zynq: add support for ARCH_MULTIPLATFORM
The majority of changes are necessary to remove dependencies on header
files within arch/arm/mach-zynq/include/mach:

  uncompress.h
    - Deleted. It is unused for ARCH_MULTIPLATFORM builds.

  uart.h:
    - Move uart definitions out of uart.h into debug/zynq.S, which is
      now the only user

  zynq_soc.h:
    - Move SCU address definitions into common.c.
    - Other #defines, such as PERIPHERAL_CLOCK_RATE, TTC0_BASE, etc, are
      unused and can be dropped
