Subject: [PATCH v6 0/5] arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

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 without forcibly selecting of the PL01X's DEBUG_LL
implementation (which doesn't work on some platforms).

- Tidy a couple of existing defconfig's so they continue to issue
  DEBUG_LL messages to PL01X when the subsequent changes come along.
- Limit DEBUG_LL_UART_NONE to platforms that support it
- Fix a potential build problem on EP93XX
- Get rid of the compatibility code that causes us to forcibly enable
  DEBUG_UART_PL01X 

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)

Daniel Thompson (5):
  ARM: versatile: Enable DEBUG_LL_UART_PL01X
  ARM: ep93xx: Enable DEBUG_LL_UART_PL01X
  ARM: Hide DEBUG_LL_UART_NONE from unsupported platforms
  arm: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX
  arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)
