Now that commit d6618d277c1a ("mmc: sdhci-pic32: update include to use pic32.h from platform_data") is merged, it's possible to compile this driver on other architectures. To avoid future breakage of this driver in the future, let's update the Kconfig so that it can be built with COMPILE_TEST enabled on all architectures.

This driver supports the DWCMSHC SDHCI controller with BST-specific enhancements including: - Custom clock management and tuning - Power management support - BST-specific register configurations - Support for eMMC and SD card interfaces - Hardware limitation workaround for 32-bit DMA addressing The driver addresses specific hardware constraints where: - System memory uses 64-bit bus, eMMC controller uses 32-bit bus - eMMC controller cannot access memory through SMMU due to hardware bug - All system DRAM is configured outside 4GB boundary (ZONE_DMA32) - Uses SRAM-based bounce buffer within 32-bit address space Signed-off-by: Ge Gordon <gordon.ge@bst.ai> Signed-off-by: Albert Yang <yangzh0906@thundersoft.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> 2025-12-17T13:14:51+00:00 Jared Kangas jkangas@redhat.com 2025-12-12T15:03:17+00:00 urn:sha1:d3ecb12e2e04ce53c95f933c462f2d8b150b965b MMC_SDHCI_ESDHC_IMX requires ARCH_MXC despite also being used on ARCH_S32, which results in unmet dependencies when compiling strictly for ARCH_S32. Resolve this by adding ARCH_S32 as an alternative to ARCH_MXC in the driver's dependencies.

This patch describes the MMC controllers on the Loongson-2K0500/2K1000, with the distinguishing feature being the use of an externally shared APBDMA engine.
