From: Raymond Mao <[email protected]> This series adds MMC support for the SpacemiT K1: an SDHCI platform driver, the SD card device-tree overlay, defconfig options, and SPL boot-device selection from the SoC strap/config registers. The SDHCI driver is usable in both SPL and U-Boot proper. It also carries two generic cmd/meminfo fixes needed on K1, whose DRAM is larger than 4 GB and split across two banks with an address hole: widen the printed addresses to phys_addr_t, and account LMB regions per bank. A flashing guide (doc/board/spacemit/k1-flash.rst) describes how to write images to eMMC. This series sits on top of three series still under review, and must be applied after them, in this order: 1. K1 clock/reset/dts migration v2 [1] (8 patches) 2. K1 SPL bring-up v4 [2] (14 patches) 3. K1 pinctrl/GPIO and SPI NOR v2 [3] (9 patches) Then this series (8 patches) [1] https://lore.kernel.org/u-boot/20260526-b4-k1-clk-reset-upstream-dts-v2-0-af815e362...@riscstar.com/ [2] https://lore.kernel.org/u-boot/[email protected]/ [3] https://lore.kernel.org/u-boot/[email protected]/ Guodong Xu (8): spacemit: k1: select boot device via config registers mmc: k1: add sdhci platform driver dts: k1: add SD card support in u-boot overlay configs: k1: enable SD and eMMC support doc: spacemit: flash on K1 SoC based boards cmd: meminfo: widen memory map addresses to phys_addr_t cmd: meminfo: fix the lmb info for large DRAM cmd: tlv_eeprom: fix accessing invalid parameter
