+Subject: [PATCH] xtest: stats: Disable fragmentation calculation for older
+ OP-TEE OS
+
+optee-os versions prior to 4.6.0 do not provide the free2_sum field in
+struct pta_stats_alloc. xtest 4.6.0 unconditionally accesses this field,
+which breaks the build when used together with older OP-TEE OS releases
+such as 4.3.0.
+
+Disable the fragmentation calculation based on free2_sum to restore
+compatibility with older OP-TEE OS versions while keeping the remaining
+statistics intact.

+Intro
+=====
+
+AndesTech AE350 Platform with OP-TEE
+
+The AE350 prototype demonstrates the AE350 platform with OP-TEE support on
+both FPGA hardware and QEMU simulation.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+ $ make andes_ae350_45_optee_defconfig
+
+If you want to customize your configuration:
+
+ $ make menuconfig
+
+Build everything
+----------------
+Note: you will need to access to the network, since Buildroot will
+download the packages' sources.
+
+ $ make
+
+Result of the build
+-------------------
+
+After building, you should obtain the following files:
+
+ output/images/
+ |-- ax45_c1_d_dsp_noncoherent_ae350_optee.dtb
+ |-- dtb/ax45mp_c4_d_dsp_ae350_optee.dtb
+ |-- boot.vfat
+ |-- fw_dynamic.bin
+ |-- fw_dynamic.elf
+ |-- Image.gz
+ |-- rootfs.ext2
+ |-- rootfs.ext4 -> rootfs.ext2
+ |-- sdcard.img
+ |-- tee.bin
+ |-- u-boot-spl.bin
+ `-- u-boot.itb
+
+How to update the bootloader and device-tree
+============================================
+
+To update the bootloader and device tree, make sure you have
+an ICEman (Andes OpenOCD [1]) and AICE [2] connection set up
+as below:
+
+ Local Host Local/Remote Host
+ .-----------------. .--------------.
+ | buildroot images| | |
+ | | ICEman host <IP:PORT>
+ | .----------. | | .--------. |
+ | | SPI_burn |<---+--socket--+->| ICEman | |
+ | '----------' | | '--.-----' |
+ '-----------------' '-----|--------'
+ |
+ USB
+ .--------------. |
+ | target | .-----v-----.
+ | board <----JTAG---| AICE |
+ | | '-----------'
+ '--------------'
+
+[1] https://github.com/andestech/ICEman
+[2] https://www.andestech.com/en/products-solutions/andeshape-platforms/aice-micro/
+
+The Andes SPI_burn tool will be located in output/host/bin.
+Use the following commands to update the bootloader and device tree:
+
+ $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0x000000 -i u-boot-spl.bin
+ $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0x020000 -i u-boot.itb
+ $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0x1E0000 \
+ -i ax45_c1_d_dsp_noncoherent_ae350_optee.dtb
+
+Note that the --addr option specifies the offset starting from
+the flash base address 0x80000000 and set by U-Boot configurations.
+e.g.
+u-boot-spl.bin: CONFIG_SPL_TEXT_BASE=0x80000000
+u-boot.itb: CONFIG_SPL_LOAD_FIT_ADDRESS=0x80020000
+ax45_c1_d_dsp_noncoherent_ae350_optee.dtb: CONFIG_SYS_FDT_BASE=0x801E0000
+
+How to write the SD card
+========================
+
+Copy the sdcard.img to a SD card with "dd":
+
+ $ sudo dd if=sdcard.img of=/dev/sdX bs=4096
+ $ sudo sync
+
+OP-TEE OS (tee.bin)
+===================
+
+The file `tee.bin` is the OP-TEE OS secure world binary.
+It provides a Trusted Execution Environment (TEE) that runs alongside Linux in
+secure mode.
+
+The OP-TEE OS binary (`tee.bin`) is packaged inside the `u-boot.itb` image on
+the AE350 platform.
+
+OP-TEE provides the following core security services:
+
+- Secure execution of Trusted Applications (TAs)
+- Secure key storage and cryptographic operations
+- Hardware-backed isolation between Secure World and Normal World
+- Secure monitor call (SMC) interface for Linux communication
+
+Linux communicates with OP-TEE through the standard OP-TEE Linux driver using
+SMC calls. This allows normal world applications to access secure services
+without exposing sensitive data to the Linux kernel.
+
+For the quad-core configuration, switch to ax45mp_c4_d_dsp_ae350_optee.dts.
+Set the following options in menuconfig:
+
+Kernel ---> In-tree Device Tree Source file names
+BR2_LINUX_KERNEL_INTREE_DTS_NAME="andes/ax45mp_c4_d_dsp_ae350_optee"
+
+Bootloaders ---> Additional build variables
+BR2_TARGET_OPTEE_OS_ADDITIONAL_VARIABLES="CFG_TEE_CORE_NB_CORE=4 CFG_NUM_THREADS=8"
+
+OP-TEE User-space Configuration (4.3.0)
+=======================================
+
+The OP-TEE user-space components are built from custom upstream
+tarballs and provide Linux support for OP-TEE OS.
+
+They can be enabled from Buildroot menuconfig:
+ Target packages --->
+ Security --->
+
+ -*- optee-client
+ optee-client version (Custom tarball) --->
+ URL of custom optee-client tarball:
+ $(call github,OP-TEE,optee_client,4.3.0)/optee_client-4.3.0.tar.gz
+
+ [*] optee-examples
+ optee-examples version (Custom tarball) --->
+ URL of custom optee-examples tarball:
+ $(call github,linaro-swg,optee_examples,4.3.0)/optee_examples-4.3.0.tar.gz
+
+ [*] optee-test
+ optee-test version (Custom tarball) --->
+ URL of custom optee-test tarball:
+ $(call github,OP-TEE,optee_test,4.3.0)/optee_test-4.3.0.tar.gz
+
+Since the custom tarballs do not have hash files,
+disable this option to build these packages.
+
+ Build options --->
+ Advanced --->
+ [ ] Force all downloads to have a valid hash
+
+OP-TEE User-space Configuration (4.6.0)
+=======================================
+
+The OP-TEE user-space components version 4.6.0 are also supported.
+
+They can be enabled from Buildroot menuconfig:
+ Target packages --->
+ Security --->
+
+ -*- optee-client
+ optee-client version (4.6.0) --->
+
+ [*] optee-examples
+ optee-examples version (4.6.0) --->
+
+ [*] optee-test
+ optee-test version (4.6.0) --->
+
+Note:
+When using optee-test 4.6.0, xtest case 4016 is expected to fail.
+This is because optee-test 4.6.0 introduces validation for the
+TEE_ERROR_SHORT_BUFFER behavior in the ED25519 sign/verify test.
+This error code did not exist in optee-os version 4.3.0, but it is
+required and tested in version 4.6.0.
+
+QEMU (AE350 simulation)
+=======================
+
+To run the andes_ae350 machine model, use the QEMU version:
+https://github.com/andestech/qemu
+
+Boot command example:
+ qemu-system-riscv64 \
+ -nographic \
+ -M andes_ae350 \
+ -cpu andes-ax45 \
+ -m 2G -smp 1 \
+ -bios none \
