ARM: brcmstb: Add debug UART entry for 74165

2024-02-01T21:51:35+00:00

BCM74165 uses the same address map as the 7278 family (v7 memory map) therefore re-use that constant and shift down the other labels to keep numerical ordering. Link: https://lore.kernel.org/r/20240129184651.2405485-1-florian.fainelli@broadcom.com Signed-off-by: Florian Fainelli

ARM: s3c: remove s3c24xx specific hacks

2023-01-16T08:26:05+00:00

A number of device drivers reference CONFIG_ARM_S3C24XX_CPUFREQ or similar symbols that are no longer available with the platform gone, though the drivers themselves are still used on newer platforms, so remove these hacks.

arm: remove zte zx platform left-over

2021-11-25T17:30:52+00:00

Commit 89d4f98ae90d ("ARM: remove zte zx platform") missed to remove some definitions for this platform's debug and serial, e.g., code dependent on the config DEBUG_ZTE_ZX. Fortunately, ./scripts/checkkconfigsymbols.py detects this and warns: DEBUG_ZTE_ZX Referencing files: arch/arm/include/debug/pl01x.S Further review by Arnd Bergmann identified even more dead code in the amba serial driver. Remove all this left-over from the zte zx platform.

ARM: imx: rename DEBUG_IMX21_IMX27_UART to DEBUG_IMX27_UART

2021-11-21T08:45:16+00:00

Since commit 4b563a066611 ("ARM: imx: Remove imx21 support"), the config DEBUG_IMX21_IMX27_UART is really only debug support for IMX27. So, rename this option to DEBUG_IMX27_UART and adjust dependencies in Kconfig and rename the definitions to IMX27 as further clean-up. This issue was discovered with ./scripts/checkkconfigsymbols.py, which reported that DEBUG_IMX21_IMX27_UART depends on the non-existing config SOC_IMX21.
