cover ARM: EXYNOS: Kconfig cleanup

This patch series aims to consolidate low level Kconfig entries for Exynos SoC series by adding missing or removing wrong dependencies, renaming entries to match a single naming convention and introducing a common parent entry for EXYNOS4212 and EXYNOS4412.

See particular patches for more detailed descriptions.

Tomasz Figa (4):
ARM: EXYNOS: Kconfig: Rename CPU_EXYNOS4210 to SOC_EXYNOS4210
ARM: EXYNOS: Kconfig: Sort out dependencies between options
ARM: EXYNOS: Kconfig: Group EXYNOS{4212,4412} into EXYNOS4X12
ARM: EXYNOS: Kconfig: Remove dependencies on particular SoCs from DT
machines

PATCH 1/4 ARM: EXYNOS: Kconfig: Rename CPU_EXYNOS4210 to SOC_EXYNOS4210

This patch renames CONFIG_CPU_EXYNOS4210 to CONFIG_SOC_EXYNOS4210 to match the convention used by rest of Exynos SoCs and correctly represent the reality (Exynos4210 is a SoC, not a CPU).

PATCH 2/4 ARM: EXYNOS: Kconfig: Sort out dependencies between options

In reply to Tomasz Figa

This patch modifies the dependencies between Exynos-related Kconfig options to represent the real dependencies between code units more closely.

Originally it was possible to enable ARCH_EXYNOS{4,5} without any SOC_EXYNOS_{4,5}.* enabled, which could end with compilation or link errors. Now ARCH_EXYNOS{4,5} is only selected when there is a SOC_EXYNOS_{4,5}.* enabled, which requires it.

IMHO board selecting SoC selecting arch seems to represent reality the best, because a board is based on particular SoC, which is based on particular arch (family).

PATCH 3/4 ARM: EXYNOS: Kconfig: Group EXYNOS{4212,4412} into EXYNOS4X12

In reply to Tomasz Figa

This patch adds CONFIG_EXYNOS4X12, which is automatically selected whenever there is at least one SoC from Exynos4x12 line enabled. All the shared dependencies of EXYNOS{4212,4412} are moved to this new option.

This fixes build with Exynos4412 enabled and Exynos4212 and Exynos4210 disabled and also allows to simplify conditional compilation in several places.

PATCH 3/4 ARM: EXYNOS: Kconfig: Group EXYNOS{4212,4412} into EXYNOS4X12

Quoted 95 lines · Tomasz Figa

This patch adds CONFIG_EXYNOS4X12, which is automatically selected whenever there is at least one SoC from Exynos4x12 line enabled. All the shared dependencies of EXYNOS{4212,4412} are moved to this new option.

This fixes build with Exynos4412 enabled and Exynos4212 and Exynos4210 disabled and also allows to simplify conditional compilation in several places.

Well, do we _really_ need to define CONFIG_SOC_EXYNOS4X12 for supporting common part of exynos4212 and exynos4412? In my opinion, it will cause confusion rather than reducing code size. Let's just use its own name for SoC.

Thanks.

Best regards,

There are files that must be compiled if any of these SoCs is enabled, for example clock-exynos4212.o (it contains clocks for both of them regardless of the misleading name).

This common Kconfig entry would be used in Makefiles for such cases.

PATCH 4/4 ARM: EXYNOS: Kconfig: Remove dependencies on particular SoCs from DT machines

MACH_EXYNOS{4,5}_DT are used for whole SoC lines, so they should depend on ARCH_EXYNOS{4,5} rather than on particular SoCs.

Hmm...your comment is correct, but we need to think again its selecting order, between ARCH name, SoC and board. In addition, in case of MACH_XXX_DT depending on SoC is rather to be supposed...

Thanks.

With device tree the situation is a bit different than with boards, because mach-exynos4-dt does not limit the scope to a single SoC, but rather to the whole Exynos4 arch/family.

Making MACH_EXYNOS4_DT select all SOC_EXYNOS4* would remove the ability to enable/disable support for particular Exynos4 SoCs, so in my opinion it is not a good option.

Selecting ARCH_EXYNOS4 is not enough for the kernel to work, because at least one SoC must be enabled.

So I think that letting the user select the SoCs he want to be supported and making MACH_EXYNOS4_DT depend on at least one of Exynos4 SoCs (which is implied by ARCH_EXYNOS4 enabled) is the most reasonable variant.

Btw. Maybe this could go in pair with something like

static char const *exynos4_dt_compat[] __initdata = {
+#ifdef CONFIG_SOC_EXYNOS4210
"samsung,exynos4210",
+#endif
/* and so on for any Exynos4 SoCs added in future... */
NULL
};

to make the kernel reject booting DT-enabled boards with unsupported SoCs. What do you think?

Best regards,
Tomasz Figa
