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 v10: - Fixed typos in the omap1 config help texts (review of Aaro Koskinen).
Changes since v9: - Removed a spuriously introduced (and unused) config variable from the netx patch (review of Paul Bolle). - Fix netx macro to ensure \rv is correctly initialized. - Rebased on v3.17rc4.
Changes since v8: - Regenerated patch series with --find-renames to properly track code movement.
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)
