[Buildroot] [PATCH v1 1/2] board/versal: increase vfat partition to 64M

[Buildroot] [PATCH v1 1/2] board/versal: increase vfat partition to 64M

[Neal Frager via buildroot]

In the process of bumping Linux kernel 6.12.10 to 6.12.40, the size of the
default Linux kernel Image file for versal products is increasing from 23.4M
to 26.9M. This is leaving limited free space in the vfat partition meaning
users may unknowingly exceed the 32M size by just adding Linux kernel configs.

To avoid potential problems, this patch doubles the size of the vfat partition
to 64M, which should be plenty of space for any configuration.

[Buildroot] [PATCH v1 2/2] configs/versal_*: bump to Linux 6.12.40

[Neal Frager via buildroot]

The memory leak patch is included with the Linux 6.12.40 release tag, so it no
longer needs to be applied to these defconfigs:
https://github.com/Xilinx/linux-xlnx/commit/9691533f6e6fd0a596ac7688e82eeea53f22c434

Also, since all Xilinx defconfigs have been bumped to Linux 6.12.40 with this
patch, the Linux 6.12.10 (2025.1) hash can be removed along with the
Linux 6.12.10 memory leak patch.

This patch has been run tested on the versal vek280 evaluation board.
This patch has been run tested on the versal vck190 evaluation board.

- CONFIG_XILINX_AIE leak
-
-Linux Kconfig options should not be exposed to user space.  This patch fixes
-a Linux kernel leak of the CONFIG_XILINX_AIE option by moving the changes
-implemented by the CONFIG_XILINX_AIE from the uapi header file to the local
-Linux kernel header file.
