c047f529e8 ARM: debug-ll: reorganize mvebu debug uart config
As we are moving dove/mv78xx0/orion into multiplatform, the debug-ll
configuration options for these platforms are conflicting with the
multiplatform configuration: enabling one of those platforms sometimes
changes the default addresses to the ones used on one of them, rather
than the one that was selected in Kconfig.

This changes the configuration so we share the physical address
configuration with mach-mvebu.

cdd2e08b21 ARM: debug-ll: fix UART configuration with ARCH_KEYSTONE
We may have multiple platforms enabled and also DEBUG_LL
configured for one of them. However if we enable ARCH_KEYSTONE,
we default to using 32-bit UART access independent of which
platform we are actually using, which can be confusing.

This changes the logic so the 32-bit default gets only
used by default if we actually configure the keystone
UART, as opposed to picking some other 8250 setting on
a kernel that has keystone support enabled.

e6ae32c343 ARM: fix DEBUG_SET_MODULE_RONX build dependencies

MMU otherwise these build errors are observed:

kernel/module.c:1738: undefined reference to `set_memory_nx'
kernel/built-in.o: In function `set_page_attributes':

This is because the pageattr functions are not built for !MMU configs as
they don't have page tables.

   cleanups and removal of code, and the final flip of config dependencies
 
 - Shmobile has several platforms that are going multiplatform, but this
   branch also contains a bunch of cleanups that they weren't able to keep
   separate in a good way. THere's also a removal of one of their SoCs and the
   corresponding boards (sh7372 and mackerel).

e6c81cce56 ARM: SoC platform updates for v4.1
Our SoC branch usually contains expanded support for new SoCs and other core
 platform code. In this case, that includes:
 
 - Support for the new Annapurna Labs "Alpine" platform
 - A rework greatly simplifying adding new platform support to the MCPM
   subsystem (Multi-cluster power management)
 - Cpuidle and PM improvements for Exynos3250
 - Misc updates for Renesas, OMAP, Meson, i.MX. Some of these could have
   gone in other branches but ended up here for various reasons.

d0440c59f5 ARM: SoC cleanups for v4.1
We've got a fairly large cleanup branch this time. The bulk of this is removal
 of non-DT platforms of several flavors:
 
 - Atmel at91 platforms go full-DT, with removal of remaining board-file based
   support
 - OMAP removes legacy board files for three more platforms
 - Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
 - Freescale i.MX25 also removes non-DT platform support
 
 Most of the rest of the changes here are fallout from the above, i.e. for
 example removal of drivers that now lack platforms, etc.

01081f5ab9 coresight: moving to new "hwtracing" directory
Keeping drivers related to HW tracing on ARM, i.e coresight,
under "drivers/coresight" doesn't make sense when other
architectures start rolling out technologies of the same
nature.

As such creating a new "drivers/hwtracing" directory where all
drivers of the same kind can reside, reducing namespace
pollution under "drivers/".

The Linux kernel still lacks DT bindings for the sh7372 INTC
interrupt controller so DT multiplatform support is not possibile.

Also, the sh7372 SoC never went into mass production anyway so to
aid migration to DT multiplatform simply get rid of sh7372 support.

878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

ea7531ac4a ARM: SoC cleanups
This is a good healthy set of various code removals. Total net delta is 8100
 lines removed.
 
 Among the larger cleanups are:
 
 - Removal of old Samsung S3C DMA infrastructure by Arnd
 - Removal of the non-DT version of the 'lager' board by Magnus Damm
 - General stale code removal on OMAP and Davinci by Rickard Strandqvist
 - Removal of non-DT support on am3517 platforms by Tony Lindgren
 
 ... plus several other cleanups of various platforms across the board.

a61cbf51f0 ARM: 8274/1: Fix DEBUG_LL for multi-platform kernels (without PL01X)
When building a multi_v7_defconfig kernel it is not possible to configure
DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more
accurately and worse, it is possible to configure a different serial
device but KConfig does not honour this request. In fact this also
overrides the user selection for some of the single platform kernels, for
example I don't think DEBUG_LL can be targeted at ICE or semihosted
supervisor for ARCH_VERSATILE.

This happens because DEBUG_UART_PL01X is automatically enabled by
some architectures and this means user decisions made regarding
the DEBUG_LL backend will be overridden. Problem is fixed by removing the
automatic enabling of this option.

d02fde7fc0 ARM: 8273/1: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX
On EP93XX uncompress.h uses CONFIG_DEBUG_UART_PHYS instead of a hard
coded serial port. This means the build breaks when DEBUG_LL
(and DEBUG_LL_UART_PL01X) is not enabled.

This is fixed by adding a new dependency.

c26b999353 ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.S
The omap1's debug-macro.S is similar to the generic 8250 code. Compared to
the 8520 code the omap1 macro automatically determines what UART to use
based on breadcrumbs left by the bootloader and automatically copes with
the eccentric register layout on OMAP7XX.

This patch drops both these features and relies instead on the generic
8250 macros:

1. Dropping support for the bootloader breadcrumbs is identical to the
   way the migration was handled for OMAP2 (see 808b7e07464d...).

2. Support for OMAP7XX still exists but it must be configured by hand
   (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

6f5194553c ARM: 8269/1: Remove DEBUG_LL_UART_NONE
Only a very small handful of platforms support DEBUG_LL_UART_NONE but it
lurks in the menus of every single platform config ready to break the
build. This is an especial problem for defconfig/oldconfig since it is
often selected by default.

This patch solves the problem by removing this option. Any platforms
still depending upon this option must be migrated.
