Subject: [PATCH 0/8] Add SD card and eMMC support for SpacemiT K1
Date: Fri, 12 Jun 2026 16:18:53 -0400 [thread overview]
Message-ID: <20260612201901.73657-1-raymondmaoca@gmail.com> (raw)
From: Raymond Mao <raymond.mao@riscstar.com>
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)
