[PATCH v8 0/9] arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

[Daniel Thompson]

This patchset removes some single-platform compatibility tricks related
to DEBUG_LL and, as a result, allows multi_v7_defconfig derived builds
to enable DEBUG_LL. Currently the user selected kbuild setting is
ignored and the PL01X's DEBUG_LL stub is silently selected instead. This
is a pain if your hardware doesn't have this cell, not least because it
takes a little time to figure out that kbuild built the wrong code.

Warning:

    silentoldconfig on PL011 single platforms will result in DEBUG_LL
    being directed at ICEDCC rather than PL011. This should only
    affect silentoldconfig since oldconfig prompts and the defconfigs have
    been updated to avoid this problem.

Changes since v7:
- Killed DEBUG_LL_UART_NONE completely and migrated over the four remaining
  platforms that relied on this (Arnd Bergmann, Russell King). This
  fixes some problems with oldconfig builds.
- Rebased on latest mainline (v3.17rc1).

Changes since v6:
- Removed a patch to limit DEBUG_LL_UART_NONE to platforms that support
  it because it almost time to drop DEBUG_LL_UART_NONE anyway (only
  four platforms still use it).
- Rebased on latest mainline (v3.16rc3).

Changes since v5:

- Shortened the list of platforms that can select DEBUG_LL_UART_NONE
  (changes Arnd Bergmann)
- Rebased on latest mainline (v3.15rc7).

Changes since v4:

- Rebased to latest mainline (and tested again). No functional changes.

Changes since v3:

- Converted from a single patch to a series.
- Tested defconfig builds of all impacted platforms.

Changes since v2:

- Switch from def_bool to bool (thanks Russell King)

Changes since v1:

- Remove pointless single platform support (thanks Arnd Bergmann)
