The Cadence QSPI driver is broken in version 6.12.36. It was fixed by a
subsequent patch:
https://lore.kernel.org/all/20250730093234.216392179@linuxfoundation.org/
Which was later backported to the 6.12 stable branch.
Bump the kernel version to the latest 6.12.x stable version to fix QSPI
support.

Texas Instuments SK-AM62 Test and Development Board
Description
===========
This configuration will build a complete image for the TI SK-AM62
board: https://www.ti.com/tool/SK-AM62.
How to Build
============
Select the default configuration for the target:
$ make ti_am62x_sk_defconfig
Optional: modify the configuration:
$ make menuconfig
IMPORTANT: make sure to use the tiboot3 firmware that match with the TI
K3 SoC boot ROM (tiboot3-am62x-{gp/hs-fs/hs}-*.bin) used on the board.
HS-FS should be the default for all TI AM6x devices but earlier version
of TI starter kit EVMs for AM6x was produced with a GP device.
See further details on e2e Forum [1] :
"Unfortunately with this transition any existing GP device based AM62x
(and AM64x) boards will no longer boot with MMC/SD card images generated"
For such existing GP device based AM62x boards, users have to provide the
tiboot3.bin name using BR2_TARGET_TI_K3_R5_LOADER_TIBOOT3_BIN.

Build:
$ make
To copy the resultimg output image file to an SD card use dd:
$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
How to Run
==========
Insert the SD card into the SK-AM62 board, and power it up through the
USB Type-C connector. The system should come up. You can use a
micro-USB cable to connect to the connector labeled UART to
communicate with the board.
