support for SoC suspend) introduced DA8XX_PLL1_BASE despite PLL1 exists only on
DA850/OMAP-L138 and da850.c even already #define'd DA850_PLL1_BASE. Kill the
duplicate macro, renaming an existing reference to it...

Move DA8XX_MMCSD0_BASE, DA8XX_LCD_CNTRL_BASE,  and DA8XX_DDR2_CTL_BASE from
<mach/da8xx.h> to devices-da8xx.c as the latter file is the only place where
these macros are used.

While at it, restore sorting the base address macros by address value in
devices-da8xx.c...

Subject: dt/flattree: explicitly pass command line pointer to
 early_init_dt_scan_chosen

This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument.  Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.

Subject: arm/dt: Make __vet_atags also accept a dtb image

The dtb is passed to the kernel via register r2, which is the same
method that is used to pass an atags pointer.  This patch modifies
__vet_atags to not clear r2 when it encounters a dtb image.

v2: fixed bugs pointed out by Nicolas Pitre

Subject: arm/dt: Allow CONFIG_OF on ARM

Add some basic empty infrastructure for DT support on ARM.

v5: - Fix off-by-one error in size calculation of initrd
    - Stop mucking with cmd_line, and load command line from dt into
      boot_command_line instead which matches the behaviour of ATAGS booting
v3: - moved cmd_line export and initrd setup to this patch to make the
      series bisectable.
    - switched to alloc_bootmem_align() for allocation when
      unflattening the device tree.  memblock_alloc() was not the
      right interface.
