4Subject: [PATCH 04/14] ARM: socfpga: stratix10: Enable SMC/PSCI calls from
5 slave CPUs
6
7Before this patch, only master CPU (CPU0) is able to
8make SMC/PSCI calls to EL3 exception handler. This patch
9allow SMC/PSCI calls from slave CPUs (CPU1/2/3) as well.

4Subject: [PATCH 06/14] ARM: socfpga: stratix10: Add Stratix10 FPGA
5 configuration PSCI services
6
7Allow PSCI layer to handle the S10 FPGA configuration (SiP) service
8calls. All these services are also known as FPGA configuration service
9layer for S10. This service layer support FPGA configuration service
10requests from OS (EL1). It acts as the middle layer between SDM
11(Secure Device Manager) and the OS. It enables OS (EL1) to invoke SMC
12call to this service layer (EL3) and pass the FPGA bit stream to SDM
13for FPGA configuration.

5
6'SET_BLOCKLEN' may occasionally fail on first attempt.
7This patch enable a small delay in dwmci_send_cmd() on
8busy, I/O or CRC error to allow the MMC controller recovers
9from the failure/error on subsequent retries.

4Subject: [PATCH 11/14] Makefile: Add target to generate hex output for
5 combined spl and dtb
6
7Stratix10 requires a hex image of the spl plus spl devicetree offset to
8the Stratix10 onchip memory located at SPL_TEXT_BASE. This patch adds
9a target to generate a hex file from the u-boot-spl binary including the
10dtb offset at SPL_TEST_BASE.
11
12Objcopy is used to convert the $(SPL_BIN).bin, which includes the spl
13dtb, to a hex file. the --change-address option is used to offset the
14hex to SPL_TEXT_BASE as objcopy on the spl binary will not result in
15a hex file appropriately offset at SPL_TEXT_BASE.

20Changes in v3:
21 -> Cleanup commit message and better describe the problem being
22 resolved
23 -> Remove extraneous hunk
24 -> use SPL_BIN instead of u-boot-spl
25Changes in v2:
26 -> Move spl hex file generation to SPL Makefile
27 -> Create hexfile from $(SPL_BIN).bin which will include the dtb

4Subject: [PATCH 12/14] ARM: socfpga: stratix10: Remove CONFIG_OF_EMBED
5
6CONFIG_OF_EMBED was primarily enabled to support the stratix10
7spl hex file requirements. Since this option now produces a
8warning during build, and the spl hex can be created using
9alternate methods, CONFIG_OF_EMBED is no longer needed.

14Changes in v3:
15 -> Revert to u-boot.img for SPL payload name
16Changes in v2:
17 -> Change CONFIG_SPL_TARGET back to u-boot-spl.hex

4Subject: [PATCH 14/14] fpga: arria10: Fix error in fpga pin configuration
5
6Pin configuration of the FPGA devicetree block should be done
7after core configuration in the arria10 fpga driver. This fix
8corrects the check of status, and ensures that the fpga pin mux
9is configured on correct configuration of the core fpga image.
