cover Clean up debugging support

This patch series cleans up some aspects of the LL debug support by:

- Removing the multi-level choice madness
- Consolidating the 8250 debug UART support
- Consolidating the PL01x debug UART support

The differences between the various 8250 debug UART implementations are:
- Physical/Virtual addresses
- Register offset shift
- Access size
- Flow control

These are now parameterised in the Kconfig. I've left OMAP because that's a complex case, but it looks like it can be adapted to it if some of the unnecessary complexity is eliminated.

Similar is done with the PL01x implementation, except a few complex cases are left - automatic detection on Versatile Express, and the Ux500 support which looks like it'll take some picking through header files to work out what the base addresses are.

The approach I've taken is to consolidate without losing any information
- what that means it that the Kconfig parameters have rather a lot of dependencies/defaults associated with them, and the main choice statement keeps all its options.

In the longer run, I want to consolidate that down to just a pair of "Kernel low-level debugging messages via 8250 UART" and "Kernel low-level debugging messages via PL01x UART" options, possibly with the base addresses/shifts/access width/flow control supplied by the user.

I've not really been able to test these because of the current breakage on ARM devel platforms caused by the "get_signal" saga, so these are RFC only at the moment.

Nevertheless, even avoiding the loss of information, I think the diffstat is quite impressive:

RFC PATCH 1/9 ARM: debug: fix wording error in DEBUG_LL_UART_NONE option help

The DEBUG_LL_UART_NONE option was moved from the top of the list to the bottom - unfortunately, it still referred to the options "below" rather than "above".

RFC PATCH 2/9 ARM: debug: clean up low level kernel debugging selection

In reply to Russell King - ARM Linux

It is silly to bury UART selection under multiple levels of choice statements, where the top level choice statement will only list about four entries when a single SoC is selected. Move the UART selection up into the top level choice statement as it was always intended to be.

RFC PATCH 6/9 ARM: debug: move 8250 debug include into arch/arm/include/debug/

In reply to Russell King - ARM Linux

Now that the 8250 debug include can stand alone without requiring platforms to provide any macros, move it into the debug directory so it can be directly included. This allows us to get rid of a lot of debug-macros include files.

RFC PATCH 9/9 ARM: debug: move PL01X debug include into arch/arm/include/debug/

In reply to Russell King - ARM Linux

Now that the PL01X debug include can mostly stand alone without requiring platforms to provide any macros, move it into the debug directory so it can be directly included. This allows us to get rid of a lot of debug-macros include files.

The autodetect case for Versatile Express and the ux500 are left alone; these are more complicated implementations.

RFC PATCH 9/9 ARM: debug: move PL01X debug include into arch/arm/include/debug/

Quoted 9 lines · Russell King

Now that the PL01X debug include can mostly stand alone without requiring platforms to provide any macros, move it into the debug directory so it can be directly included. This allows us to get rid of a lot of debug-macros include files.
The autodetect case for Versatile Express and the ux500 are left alone; these are more complicated implementations.

Certainly a move in the right direction. For highbank:

cover Clean up debugging support

In reply to Russell King - ARM Linux

Quoted 6 lines · Russell King - ARM Linux

This patch series cleans up some aspects of the LL debug support by:
- Removing the multi-level choice madness
- Consolidating the 8250 debug UART support
- Consolidating the PL01x debug UART support

Quoted 8 lines

The differences between the various 8250 debug UART implementations are:
- Physical/Virtual addresses
- Register offset shift
- Access size
- Flow control
