treewide: Kconfig: use bool instead of tristate

2026-07-10T21:45:57Z

U-Boot does not support modules, so having tristate options is useless. Therefore this patch does a blind replace of all tristate options to bool tree-wide.

ufs: amd-versal2: Fix missing .priv_auto in driver registration

2026-07-08T06:55:51Z

Add missing .priv_auto field to the driver. Without it, struct ufs_versal2_priv is never properly allocated and dev_get_priv() returns NULL, leading to DDR corruption at low DDR addresses.

ufs: qcom: Remove redundant POST_CHANGE clock setup call

2026-05-18T09:04:14Z

The ufs_qcom_init() function was calling ufs_qcom_setup_clocks() with POST_CHANGE twice. The first call after setting PA_TXHSADAPTTYPE correctly enables the device reference clock. The second call after ufs_qcom_advertise_quirks() is redundant as the clock is already enabled.

drivers: ufs: qcom: Initialize and enable clocks before hardware access

2026-05-18T09:04:14Z

Move UFS clock initialization and enabling before hardware setup to ensure clocks are running when accessing UFS registers. Previously, U-Boot depended on earlier bootloader stages to initialize UFS clocks. When these bootloaders failed to do so, UFS registers became inaccessible, causing initialization to fail. This change makes U-Boot initialize and enable UFS clocks early in the init sequence, removing the dependency on previous bootloaders.

ufs: core: Fix heap corruption due to out of bounds write

2026-04-22T08:06:01Z

The ufshcd_read_string_desc() can perform out of bounds write and corrupt heap in case the input utf-16 string contains code points which convert to anything more than plain 7-bit ASCII string. This occurs because utf16_to_utf8(dst, src, size) in U-Boot behaves differently than Linux utf16s_to_utf8s(..., maxlen), but the porting process did not take that into consideration. The U-Boot variant of the function converts up to $size utf-16 fixed-length 16-bit input characters into as many 1..4 Byte long variable-length utf-8 output characters. That means for 16 Byte input, the output can be up to 64 Bytes long. The Linux variant converts up utf-16 input into up to $maxlen Bytes worth of utf-8 output, but stops at the $maxlen limit. That means for 16 Byte input with maxlen=32, the processing will stop after writing 32 output Bytes. In case of U-Boot, use of utf16_to_utf8() leads to potential corruption of data past the $size Bytes and therefore corruption of surrounding content on the heap. The fix is as simple, allocate buffer that is sufficient to fit the utf-8 string. The rest of the code in ufshcd_read_string_desc() does correctly limit the buffer to fit into the DMA descriptor afterward.

Assert Rockchip UFS controller resets during initialization and HCE enable, as it is done by the Linux driver. This is required to make some UFS chips, such as Foresee FEUDNN064G-C2G0, work properly. Note that the resets were already requested in the probe function, just not used.
